CCSTUDIO-THEIA: Removed workspace folder is recreated on next CCStudio startup

Ernst van der Pols — Fri, 07 Aug 2026 14:42:45 GMT

Part Number: CCSTUDIO-THEIA
Other Parts Discussed in Thread: CCSTUDIO

Really a not so problematic issue observed when investigating the "related" issue in a temporary workspace.

Close CCStudio after working in workspace "temp"
Delete the workspace folder "temp" in Windows
Restart CCStudio
- It tries to reopen the removed workspace, and recreates the "temp" folder in its original location. Empty.

Fun fact: I have none of the AI agents activated that are now supported in this CCS version. They might have guessed whether the "temp" meant "temporary" and skip trying to reopen it, or "temperatureAnalysis" and not only recreate the folder, but also a reasonable contents that you might expect there.

I guess the observed behaviour is often a feature (wanted behaviour) and not a bug (unwanted behaviour). But a notification would be nice.

MSP430G2553-Q1: Code expression stuck

Nishant Gupta — Thu, 06 Aug 2026 21:20:14 GMT

Part Number: MSP430G2553-Q1
Other Parts Discussed in Thread: MSP430G2553

I am using MSP430G2553 with Code Composer Studio (CCS) 12.8.1. My project builds and runs successfully.

However, the variables in the Expressions window do not update while the program is running. The values are only refreshed after I click Pause/Halt. I have already enabled Continuous Refresh, but the behavior remains the same.

Is this a limitation of the MSP430G2553/debugger, or is there any CCS setting that enables real-time updates of the Expressions window while the CPU is running? If not, what is the recommended method to continuously monitor variable values during program execution?

Thank you.

TMS320F28379D: CCS 20.4.0 repeatedly jumps to halted code location

B R — Thu, 06 Aug 2026 14:48:55 GMT

Part Number: TMS320F28379D

Using CCS 20.4.0 with an F28379D CPU1 project, when I select Pause or Pause All, CCS repeatedly returns the editor to the halted source line. I cannot open another source file, scroll elsewhere, or inspect another function while halted.

Already tried disabling Realtime Mode and continuous refresh, using DRTM, restarting CCS.

Is this a known CCS 20.4.0 issue, and can automatic navigation to the program-counter location be disabled?

LP-MSPM0L1306: Setting up both OPAs for differential input

Joseph Bailey — Wed, 05 Aug 2026 19:37:47 GMT

Part Number: LP-MSPM0L1306

Hello,

I am currently prototyping a system that will use a sensor with a differential output. When configuring the OPA's through the system configuration, and following the given example in the techinical reference manual, my voltage across the inputs jumps from expected mV output to a voltage around 1.5V. Maybe, I am misinterpreting the reference manual that everything will be handled internally, but some help would be appreciated.

CCSTUDIO-THEIA: Once part of System Project a project's Build action no longer works in CCS Theia

Ernst van der Pols — Wed, 05 Aug 2026 15:01:05 GMT

Part Number: CCSTUDIO-THEIA
Other Parts Discussed in Thread: CCSTUDIO, TMDSCNCD28388D

Dear support team,

I am very happy with the implementation of the System Project user interface in the new CCStudio version 21.0. Unfortunately, a related issue that was already present in the previous version 20.5, where I was using a 'system.xml' project imported from the last non-Theia CCS, is still present.

When you have assigned an existing project in the workspace, e.g. for CPU1, to the corresponding core in the System Project, the Build Projects and the Re-build Projects actions on the 'child' project no longer work. That is, the Info-panel with message Building... does appear, but after a second or so disappears, and no file is compiled.

Strangely, the Clean Projects action still works, as well as Debug Project. But the build that is normally done before launching the debug session is skipped, so you might end up debugging an outdated version of the executable(s).

Once part of a System Project, the only way to make sure individual core projects are compiled is a Build via the System Project. When you disconnect the core project from the System Project, normal behaviour is restored.

I could not find a message in the ccs_theia.log that would relate to this issue.

Note: I posted this earlier in the C2000 microcontrollers forum, but this forum suits better.

Hello,

We are trying to get PX5 RTOS running on the Cortex-R5 of the AM64x Evaluation Module for a mutual customer in the industrial control space. We have found a series of examples and can build them cleanly with our CCS 12.4 tools. However, whenever we try to download them via Debug As -> Code Composer Debug Session, selecting only the MAIN_Cortex_R5_0_0 we get a series of errors, starting with:

Attempting to disconnect the XDS110 debug cable and reconnecting, followed by Retry, we get:

The board SW settings are: SW2 all on, except for 3 SW3 all off

We have spent a day fiddling with this, but we suspect we are just missing a fundamental set somewhere in the sequence. Any help would be greatly appreciated!!

CCSTUDIO-THEIA: Loss of focus when compiling and chating with CODEX in the same time

Nicolae Grigoras — Sun, 02 Aug 2026 11:21:42 GMT

Part Number: CCSTUDIO-THEIA
Other Parts Discussed in Thread: TMS320F280049C

HI guys,

A small but annoying behavior - see below a polished bug report that i asked CODEX to generate.

I do not know if this is intended or a funtionality bug - but it's annoying.

Title

Build completion unexpectedly steals keyboard focus from Codex Chat and redirects typing into the source editor

Environment

Code Composer Studio: CCS 21.x (C:\ti\ccs2100)
Operating system: Windows
Target project: TMS320F280049C C2000 project
Active source file: C2000-MPPT02.c
Build configuration: CPU1_RAM
Codex Chat open inside CCS

Description

While a project build was running, I was typing a message in the Codex Chat input field.

When the build completed, CCS unexpectedly moved keyboard focus away from the chat input and into the source editor. The editor navigated to C2000-MPPT02.c near the main() function.

Because I was still typing, the remaining text was inserted directly into the C source file instead of the chat window.

Steps to reproduce

Open a C source file in the CCS editor.
Open Codex Chat.
Start building the active CCS project.
While the build is running, place the cursor in the Codex Chat input and begin typing.
Allow the build to finish while continuing to type.
Observe whether focus moves from Codex Chat to the source editor.

Expected behavior

Build completion should not change keyboard focus when the user is actively typing in Codex Chat.

The chat input should retain focus unless the user explicitly selects another view or editor.

Actual behavior

At build completion:

Keyboard focus moved from Codex Chat to the source editor.
CCS navigated to the main() function.
Continued keyboard input was inserted into the source file.
The source file was unintentionally modified.

Impact

Severity: Minor UI issue, but with potential data-integrity consequences.

The behavior can silently corrupt source code because the user may not immediately notice that keyboard focus changed. In embedded or safety-related projects, accidental source modification is especially undesirable.

Frequency

Observed once so far. Reproducibility has not yet been confirmed.

Suggested behavior

Never steal keyboard focus from an actively edited chat input when a build completes.
Navigation to a source location should not automatically focus the editor.
If build completion must reveal a source location, the currently focused input control should retain keyboard focus.

Workaround

After build completion, verify that Codex Chat still has focus before continuing to type. If text enters the source editor, immediately undo the unintended edit and confirm that the file was not saved with the accidental text.

Thank you.

Hi all,

CCS VERSION 20.1.x

CCS Debug Issue:

After debugging with the network disconnected, upon reconnecting to the network, a "Reconnecting to TI Cloud Agent..." prompt appears.

If attempting to start a new debug session at this point, a "Module is reconnecting" error occurs.

If "Cancel" is selected on the "Reconnecting to TI Cloud Agent..." dialog, CCS restarts. However, after reopening CCS, the "Reconnecting to TI Cloud Agent..." prompt appears again.

Hi Experts,

Customer is planning to implement F28E120SC for Instaspin FOC application with DRV8323.

Downloaded the MOTORCONTROL-SDK (version 6.00.00.00), however, unable to view them in CCS. See below transcript from customer:

I have this version of motor control SDK install but CSS is not importing. I tried in version 20.4 as well as 21 but of no use. I am attaching the image of what I have tried.

I had tried by adding proper paths where the 6.0 version of Motorcontrol SDK is present. Additionally when I check the resource explorer even in the latest ccs(21.0) it shows the version 5.04 as the latest motor control SDK.

One more thing I manually tried finding F28E12 related code for Instaspin FOC in the Motorcontrol SDK installation area, but other than some libraries, I am unable to find them.

For your further assistance. Thank you.

AM263P4-Q1: AM263P4-Q1: MCAN4 works in internal loopback on R5FSS1-0 but external CAN stays in Synchronizing state (RXPIN=0)

Wana -- — Thu, 30 Jul 2026 08:45:44 GMT

Part Number: AM263P4-Q1
Other Parts Discussed in Thread: AM263P4

Hi TI Team,

I am working with the AM263Px ControlCARD and a modified version of the mcan_external_read_write example. I am investigating an issue with MCAN4 when running on R5FSS1-0 (Cortex_R5_2). The same functionality works correctly on R5FSS0-0 (Cortex_R5_0).

I have verified that the following are identical between the working and non-working projects: MCAN4 instance and base address (0x52640000), bit timing configuration, Message RAM configuration, standard ID filter configuration, pinmux settings, and IO-expander/transceiver configuration (MCAN_SEL=0, STB=1, SPI1_SEL=0). MCAN also successfully enters Normal Mode (OPMODE=0) in both cases.

A key observation is that internal loopback mode works correctly on R5FSS1-0. In internal loopback, transmitted frames are successfully received back, RX buffers are updated, filters work correctly, and received IDs/data match transmitted values. This suggests that the MCAN peripheral, Message RAM, filters, and TX/RX paths inside the MCAN module are functioning correctly on R5FSS1-0.

However, in external CAN mode, the behavior differs significantly:

Working project (R5FSS0-0):

RXPIN=1

TXPIN=0

ACT=1

Non-working project (R5FSS1-0):

RXPIN=0

TXPIN=0

ACT=0

TXPEND=0x00000001

TXDONE=0x00000000

BO=0

EP=0

LEC=7

DLEC=7

The controller appears to remain in the Synchronizing state (ACT=0), the transmit request never completes (TXPEND=1, TXDONE=0), and MCAN_getRxPinState() continuously reports RXPIN=0 (dominant). On the working project, RXPIN=1 (recessive) and the controller reaches the Idle state (ACT=1).

One additional difference between the setups is the boot flow:

Working example: Running on R5FSS0-0, loaded through CCS in DevBoot mode.
Non-working application: Running on R5FSS1-0, booted through SBL using OSPI 8S (Octal) boot mode.

Given that internal loopback works correctly on R5FSS1-0, but external mode remains stuck with RXPIN=0 and ACT=0, could there be any known MCAN4 clock, resource ownership, reset, pinmux, boot-mode, or R5FSS1-0 specific initialization requirement that differs between the DevBoot/CCS flow and the OSPI 8S + SBL boot flow?

Any guidance on why MCAN4 would continuously report a dominant RX state (RXPIN=0) in external mode on R5FSS1-0 would be greatly appreciated.

Thank you.

Hello,

I am interested in running the EtherCAT Cia402 Example on my AM263P Control Card. If i understood correctly, the on board PHY does not support EtherCAT. Hence i would like to run the example with the industrial Ethernet Add-on board. I have a few questions:

Is it possible to run EtherCAT in the configuration AM263P CC + Industrial Ethernet Add-On Board?
Do you have any Examples adapted for the CC + Industrial ETH Addon configuration? The industrial communications SDK seems to only provide Board examples for LP boards + on Board ETH. Is it possible to port the examples from LP -> CC without much effort?

As I dont have much experience with CCs or the AM263P Platform, i would be very thankful for your support.

With kind regards

MSPM33-SDK: [MSPM33C321A] : question about "eeprom_emulation_type_b" example project

Sebastien Le Diouris — Tue, 28 Jul 2026 13:14:06 GMT

Part Number: MSPM33-SDK

Hello,

I want to create a new driver for manage an EEPROM emulated, so I downloaded the example "eeprom_emulation_type_b" example project.

I have some questions, but I will ask question by question, to not mix everything

Regarding sector erase management, something is not fully clear, what is the diffrence between these functions :

DL_FlashCTL_eraseMemory

DL_FlashCTL_eraseMemoryFromRAM

Other point regarding this functions, if I want to erase one sector, I have to set this:

DL_FlashCTL_eraseMemoryFromRAM(FLASHCTL, EraseSectorAddress, DL_FLASHCTL_COMMAND_SIZE_SECTOR);

In the example, EraseSectorAddress takes the value, 0x2000, 0x2800, 0x3000, 0x3800, 0x4000 and 0x4800.

0x800 each time because a size sector is 2KB (0x800)

But the EEPROM is 32KB, so 16 sectors, here there is only 6 sectors erased, which address to erase to 10 others sectors ?

Thanks

UNIFLASH: UniFlash 9.6 / CCS DebugServer (DSLite) fails with boost::filesystem::create_directories when Windows username contains non-ASCII characters

승현 박 — Wed, 22 Jul 2026 00:39:17 GMT

Part Number: UNIFLASH
Other Parts Discussed in Thread: TMS320F280039C

Environment

OS: Windows 11 Pro (64-bit)
User account: Windows username contains Korean (non-ASCII) characters
UniFlash: 9.6.0.5764
CCS: Latest CCS (same issue)
Device: TMS320F280039C
Emulator: XDS110 (or your actual emulator)

I cannot use either CCS or UniFlash to connect to or program my F280039C device.

Both CCS and UniFlash fail before attempting to connect to the target.

The problem appears to occur inside DebugServer (DSLite).

[ Error ]

Version: 9.6.0.5764

Executing the following command:
> "...DebugServer\bin\DSLite" flash flash --config ... --list-cores

boost::filesystem::create_directories:
[system:123]:
"C:\Users\?\ti",
"C:\Users\?"

If this continues, please run fsclean or set TI_APPDATA_DIR to directory you have permissions to access

The Korean username is displayed as "?".

It appears DebugServer cannot create its working directory because the Windows user profile contains non-ASCII characters.

I verified that:

DSLite itself launches correctly.
The .ccxml file is valid.
The project path contains only ASCII characters.
The error occurs before any JTAG connection.
The same problem occurs in CCS and UniFlash.

I also tried all of the following environment variables:

TI_APPDATA_DIR
USERPROFILE
HOME
TEMP
TMP
HOMEDRIVE
HOMEPATH

But, The error remains exactly the same.

*Questions*

Is this a known limitation or bug in UniFlash 9.6 / DebugServer?
Is there any workaround without creating a new Windows account that has an ASCII-only username?
Is there a newer DebugServer or patch that correctly supports Unicode Windows usernames?
Why does TI_APPDATA_DIR appear to be ignored?

Thank you.
