UNIFLASH: Using CLI interface to read device's unique id back

Sal Ye — Mon, 11 May 2026 09:56:29 GMT

Part Number: UNIFLASH

Hi expert,

We now have a customer request to use UNIFLASH Command Line Interface to read back the device unique id for datalog.

Is there any method to read a certain value from flash address and overwrite to a certain file (like .txt file)?

I see there supports to use read command with certain flash address range, while this can only been used to create a firmware.bin file.

I would like to ask if there any other method to achieve this customer request with CLI interface.

Thanks for your support!

B.R.

CODECOMPOSER: CCSTUDIO-THEIA: Clean step uses forward slashes in DEL commands on Windows, leaving .lst files undeleted

V Stoltz — Thu, 07 May 2026 11:08:18 GMT

Part Number: CODECOMPOSER

Hello,

I'm reporting an inconsistency in the Clean step on Windows hosts that
leaves some build artifacts behind.

Environment
-----------
- CCS Theia version: 20.5.1 (not working either with 20.4.1)
- Host OS: Windows 11 Home, 25H2
- Compiler: TI v21.6.1 LTS
- Target device: CC430F5137 (probably no related)
- Project type: standard CCS project, managed make build

Issue
-----
When running Project -> Clean (or Rebuild), the generated DEL commands
in the build console use inconsistent path separators. Specifically:

DEL /F "Internal/Analysis.lst" <-- forward slash, NOT executed by cmd.exe
DEL /F "Internal\Analysis.obj" <-- backslash, executed correctly

As a result, .lst files accumulate in the build configuration folder
across rebuilds, while .obj files are correctly removed. The build
output itself is unaffected (binaries are correct), but "clean" no
longer means clean, and disk usage grows over time.

The root cause appears to be that Windows cmd.exe interprets a
forward-slash path argument as a command-line option rather than a
file path under some conditions, causing the DEL to silently no-op.

Steps to reproduce
------------------
1. Create or import any CCS project on a Windows host
2. Build the project (any configuration)
3. Run Project -> Clean
4. Observe the build console: DEL commands targeting .lst files use
forward slashes; DEL commands targeting .obj files use backslashes
5. Check the build folder: .lst files remain on disk after clean

Expected behavior
-----------------
All DEL commands generated by the clean step should use the native
Windows path separator (backslash) consistently, so that all listed
files are actually removed.

Workaround
----------
Disabling .lst generation (Properties -> Build -> MSP430 Compiler ->
Assembler Options -> uncheck listing file generation) avoids the
issue by ensuring no .lst files exist to be cleaned. This is a
workaround, not a fix.

This is just for you, I can live with it.

Thank you.

RE: C2000WARE: Runtime object view(ROV) is unable to connect to target due to Error ie unable to find method(setOFReader)

It does not support COFF, so I think you will need to use ROV Classic instead of the regular ROV.

TMS320F28034: Tool to visualize memory fragmentation due to DP alignment

Jason Wiseman — Fri, 08 May 2026 18:26:16 GMT

Part Number: TMS320F28034

I am looking for a tool to visualize memory usage in the ebss section that accounts for unusable sections due to data page alignment. We are running out of RAM but not 100% of the RAM is being used due to these gaps/holes. I understand that the linker is doing a good job at minimizing code space and execution time via DP loads. I image a suitable tool would calculate the percentage of wasted RAM and help us better organize our global variables by help us visualize where these gaps are.

Note this is for a legacy code base with a mix of global variables (int, long) as well as global structs and arrays.

Regards,

Jason

Jason Wiseman — Thu, 14 May 2026 14:32:48 GMT

Thanks Matthew,

The Memory Allocation view shows bar graphs and a % of resources used along with a breakdown of which section use what percentage. I think your python tool would be exactly what I need. What version of ofd2000.exe are you using that has a -t option? Is there another format (.xml?) that the python script will accept?

AM6442: AM64x: Understanding EHRPWM_SOCA vs physical pin output and 40 MHz requirement on custom board.

Ravilla Dinesh — Tue, 21 Apr 2026 16:21:51 GMT

Part Number: AM6442

Hi TI Team,

I am working on an AM64x-based custom board using RT- Linux SDK, and I have a question regarding ePWM configuration, pin availability, and EHRPWM_SOCA usage.

In the SoC-level DTSI (main dtsi), I see that ePWM instances EPWM0 to EPWM8 are defined and enabled. When I tested the same software on the TI EVM board, I was able to configure and run the ePWM modules successfully.

However, on my custom board, only a limited number of pins are routed out, and no EPWM0 to EPWM8 pins are physically available.

My requirement is as follows:

I need to use EHRPWM_SOCA.
The signal frequency requirement is ~40 MHz
I initially expected to drive this as a pin signal, similar to EPWM outputs

custom board pins:

TRM AM64x Sitara™ Processors :

Can we use EHRPWM_SOCA to drive a 40 MHz external signal?

Thanks & Regards,
Ravilla Dinesh.

Hi Vinu,

Based on your inputs, the issue is now resolved. We are able to generate ~41 MHz on ECAP1_IN_APWM_OUT pin C17 in AM6442 with the given configuration.

&main_pmx0 {
    main_ecap1_pins_default: main-ecap1-pins-default {
        pinctrl-single,pins = <
            AM64X_IOPAD(0x0258, PIN_OUTPUT, 2) /* (C17) MCAN1_TX.ECAP1_IN_APWM_OUT */
        >;
    };
};

&ecap1 {
    status = "okay";
    pinctrl-names = "default";
    pinctrl-0 = <&main_ecap1_pins_default>;
};

Thanks & Regards,

Ravilla Dinesh.

LP-AM261: LP-AM261: Secure Boot

Payal Deshmukh — Thu, 14 May 2026 09:42:24 GMT

Part Number: LP-AM261

Hello everyone,

I am currently working on the AM261x-LP platform and trying to enable and understand the secure boot flow on my system.

I have been referring to the official documentation: https://software-dl.ti.com/mcu-plus-sdk/esd/AM261X/latest/exports/docs/api_guide_am261x/SECURE_BOOT.html

Here is what I have done so far:

I built the SBL image using the following make command:
make -s -C examples/drivers/boot/sbl_ospi_multicore_elf/am261x-lp/r5fss0-0_nortos/ti-arm-clang all DEVICE=am261x DEVICE_TYPE=HS
This produced the file: sbl_ospi_multicore_elf.Release.hs.tiimage
1. Similarly, I built the application image using the command:
  make -s -C examples/drivers/gpio/gpio_led_blink/am261x-lp/r5fss0-0_freertos/ti-arm-clang all DEVICE=am261x DEVICE_TYPE=HS
  This produced the file: gpio_led_blink.mcelf.hs
I successfully flashed (non-secure images) sbl_ospi_multicore_elf.tiimage and gpio_led_blink.mcelf. Both the OSPI bootloader and the application boot and print output on the serial console correctly.
However, when I flash (secure images) sbl_ospi_multicore_elf.Release.hs.tiimage and gpio_led_blink.mcelf.hs, I do not see any output on the serial console.
I have not converted the device to HS-SE device yet. Do I need to convert the device to HS-SE?
Is there any way to test the secure boot without converting the device to HS-SE? (Secure boot on HS-FS / GP device).
How to convert device to HS-SE type? I have requested for AM261X-TIFS-SDK, but not received yet.
Is there any way, to test secure boot without burning the keys?

In one post on TI forum, I read about the trial run mode. Does this also need the burning of the keys? How to execute trial mode?

I have read about enabling secure boot and understand that when building the SBL and application using the make commands, the generated binaries (with the extension .hs) are already signed. From what I gather, these images use a TI-dummy key for signing by default. Is that correct?

Could anyone please help me understand the process to test and verify secure boot process?

Also I want to understand the following topics:

What is the difference between device type HS-FS and GP?
When I build the example code or SBL without setting DEVICE_TYPE=HS, gpio_led_blink.mcelf and sbl_ospi_multicore_elf.tiimage are generated. Are these images unsigned? and thse images are generated for which device type HS_FS or GP?
How to identify the device type (GP/HS-FS/HS-SE) and the generated imgage is for which device type?

Thanks,

Payal

AM6442: XDS200 left LED not blinking after connecting to different host PC

Ravilla Dinesh — Thu, 14 May 2026 07:08:01 GMT

Part Number: AM6442

Hi Team,

I am using an XDS200 external debug probe with an AM64x EVM on a Linux host machine (Ubuntu).The XDS200 was working fine initially. However, after I disconnected the USB cable from the original host PC and connected it to a different host PC, the left LED on the XDS200 stopped blinking and the device is no longer detected.

Symptoms:
- XDS200 left LED is not blinking.
- Device not visible in lsusb (no Texas Instruments entry).
- Running update_xds2xx.sh xds200 gives: Error: Failed to open port connection: xds2xxu: 0x0.
- No USB enumeration in dmesg when plugging in.

Thanks & Regards,

Ravilla Dinesh.

Hi Whitney,
thanks for the reply.

Our project is not built with EABI , it is --abi=coffabi.

The issue with XDC tool (xdctools_3_62_01_16_core)

ROV is expecting :: xdc.rta.Formatter.setOFReader(ofReader)

but in file(Model.xs ) it is :: xdc.jre.xdc.rta.Formatter.setOFReader(ofReader);

path :: C:\ti\ccs1210\xdctools_3_62_01_16_core\packages\xdc\rov

Can you please share the link for XDC((Model.xs) tool or driver that support or compatible with ROV

Regards

I am using CCS 12.8.1 with a TMS320F28388S and trying to attach to both CPU1 and its CLA without disturbing the system. Both have the “Halt the target on a connect” option unchecked. When I attach to the running system, CPU1 continues running as expected. But CPU1_CLA1 halts. Is there any way to prevent that?

Jason,

Have you tried the memory allocation viewer in CCS, under view in the tool bar,

Another thing to try would be to optimize for size vs speed in the project properties

I'll also ask some of my co-workers in our SW tools team if they have any ideas based on their experience.

CCSTUDIO-THEIA: Cannot change project settings

Scott Specker — Mon, 11 May 2026 23:32:19 GMT

Part Number: CCSTUDIO-THEIA

I have been unable to change project settings in CCS. For example, I open up project properties, go to the compiler and change the optimization from level 2 to level 0. But when I click "Save and Close" nothing happens.

If I close the dialog by clicking the X in the corner of the dialog, nothing changes.

The only way I've found to change settings is to change my .projectspec file and reimport the project.

Is this a known bug in CCSv20.5.0 and 20.5.1. I've tried this with different targets and different settings with similar results.

Thanks,
Scott

Whitney Dewey — Wed, 13 May 2026 14:51:18 GMT

Is your project built for EABI output format? I believe this version of ROV only supports elf. You can also try using ROV Classic if this version isn't working.

Unfortunately we don't support SYS/BIOS anymore, so we might be limited in what help we can provide and compatibility with the latest versions of CCS.
