TMS320VC5502: Troubleshooting C5502 Hardware Initialization: Seeking Expert Guidance on Persistent Memory Reading Issues

JUN-TING LIU

Tool/software:

I am encountering an issue with initializing the C5502 hardware.
When I try to execute the main.c code, CCS continuously shows 'Trouble Reading Memory' and jumps to the location in SYS_INI.asm where PLL initialization is attempted, but none of the contents in SYS_INI.asm are executed.
I have tried checking the GEL file, the VC5502.cmd file, and performing a test connection, but I can't identify any issues.
Therefore, I would like to ask for advice from all the experts:
What other approaches can I take to debug this issue?
If there are other files or details you need me to provide, please let me know!
This problem has been troubling me for weeks, and I'm very grateful for your help!

Console log:

C55xx: GEL Output: OnReset.
C55xx: GEL Output: C5502_Init Complete.
C55xx: Trouble Reading Memory Block at 0x4ed1 on Page 1 of Length 0x1: (Error -1143 @ 0x4ED0) Device core was hung. The debugger has forced the device to a ready state and recovered debug control, but your application's state is now corrupt. You should have limited access to memory and registers, but you may need to reset the device to debug further. (Emulation package 9.12.0.00150)

Hi Jun-ting,

What C5502 board are you using (custom board or C5502 EVM)? What CCS target configuration were you using (C5502 or C5502 EVM)? What GEL file are you using? What is your boot mode?

Best regards,

Ming

Hi Ming-Wei,

I am using a custom C5502 board.
My boot mode is no boot, with BOOTM2, BOOTM1, and BOOTM0 set to 0 0 0. I use external DIP switches to control them.

Additionally, I encounter trouble reading memory at address 0x4ED1, where the variable LED_state is stored. This address should be defined in DRAM within the GEL file, so I believe it should not be out of the permissible range.

Hi Jun Ting,

Can you access to this memory area using the CCS memory browser after connecting to the target, but before the program loading?

Best regards,

Ming

Hi Ming-Wei,

Are you referring to before or after pressing "debug"?
If it's before pressing "debug," I can open the memory browser, but it doesn't display anything.
If it's after pressing "debug," I have set a breakpoint at the first line of main.c, and I am able to modify the values in the memory browser,
even after encountering the "Trouble Reading memory" issue. I can still modify specific address values through the memory browser.

Best regards,

Hi Jun Ting,

With the same setting, can you try to load and run one of the C5502 example programs, like C:\ti\C55xxCSL\examples\c5502\csl\gpt\gpt1?

Best regards,

Ming

Hi Ming-Wei,

I tried to find similar files, but couldn't locate them in any version of the folders. I also searched through all the examples directories and opened each one, but didn't see any files related to the c5502. Could it be that I missed a step in the download process?

Additionally, I tried running the Hello.c sample code from CCS, which contains just a printf("hello world") statement. When I executed it, "hello world" was displayed correctly in the console.

Hi Jun Ting,

You can download the C55x CSL 1.0.0 from https://dr-download.ti.com/software-development/driver-or-library/MD-0MVQS9HBZ7/01.00.00.00/sprc133.zip

C5502 Examples are at C:\ti\C55xxCSL\examples\c5502\csl.

Hi Ming-Wei,

I attempted to use the C55xCSL you provided, but it might be because the versions of CCS I am using (V7.4 and V12.4) are too new, and they cannot import .pjt files. Therefore, I tried to adjust the Project Properties according to the .pjt file settings. Currently, I am encountering an issue (as shown in the image), where even though I have set the General to C5502, it still displays "Chip not defined".

I also tried downloading a new version of CXL-Lowpower (03.08.01.00), but it seems that the examples included do not support the C5502. Do you have any suggestions?

Best regards,

Jun Ting

Hi Jun Ting,

Since the C55XXCSL uses the CCS 3.3 project format, please import the CCS project from "Import Legacy CCSv3.3 Project". I have tested it, it works.

I attempted to import the "Import Legacy CCSv3.3 Project" using CCS versions 7.4 and 12.4. However, after importing, I discovered that the project requires the installation of "XDAIS 1.0". The oldest version available on the official website is V6.23.

I tried to find a solution on forums, and it seems that the last person who encountered this issue resolved it by deselecting "XDAIS 1.0". I attempted the same, but it led to a series of errors (as shown in the attached image). I have been trying to resolve this for a few days but seem unable to circumvent the need for "XDAIS 1.0".

Additionally, there were errors during the import which generated a log file, which I have also attached for your reference. My operating system is Windows 11, and I typically use CCS versions 7.4 and 12.4. Do you have any suggestions?

Best regards,

Jun Ting

Hi Jun-ting,

The main build errors are not due to the missing XDAIS. It is due to missing csl5502.lib. You may need to check the library include paths and names in you CCS project settings and the environment variables.

If you absolutely need XDAIS, please download and install XDAIS 7.24.00.04 and hope it will work backward compatible with your CCS project.

Best regards,

Ming

Hi Ming-Wei,

I've attempted to correctly link all the include folders as shown in the attached image, and I have also downloaded the XDAIS version 7.24.00.04 that you mentioned. However, it seems that CCS is unable to recognize the newer version of XDAIS and continues to prompt me for XDAIS 1.0.0.

Could there be an issue with my CCS settings? How should I modify the settings in CCS versions 7.4 and 12.4?

Thank you for your assistance!

Best regards,

Jun Ting

Hi Jun-ting,

Can you deselect the XDAIS 1.0.0 to try again?

Hi Ming-Wei,

Thank you for your suggestion. I did come across similar advice on the forums. Unfortunately, implementing it on my device resulted in a series of C/C++ problems, which included 21 errors and 5 warnings, as depicted in the attached image.

Hi Jun-ting,

As I mentioned in previous post, the build errors are not due to the missing XDAIS. It is due to missing csl5502.lib. You may need to check the library include paths and names in you CCS project settings and the environment variables to make sure the csl5502.lib is actually linked to the CCS project.

Best regards,

Ming

Hi Ming-Wei,

Thank you for your guidance. I have attempted to connect most of the folders and files, and I have resolved all problems except for three remaining errors. One of these errors, Error code 16019, does not seem to have a clear solution according to my research on the internet. It appears that the remaining two issues may be caused by this as well. Do you have any suggestions on how I might address this situation?

Best regards,

Hi Jun-ting,

First of all, I can import and build the gpt3 example for c5502 with CCS 10.40.00 and XDAIS 7.40.00:

I do have to change a few things:

I do have CCS 10.40, xdais_7_24_00_04 and C55xxCSL installed at c:\ti (TI default installation folder) and the following settings for CCS --> Window --> Preferences --> Products:

Hi Ming-Wei,

After several days of attempts, I have done two things:

I tried to run various examples (gpt/mcbsp, etc.) in CCS version 10.4, and I also couldn't clean/rebuild the project. During the import, I received an error log, which is as follows:

I attempted to resolve the issue mentioned above in CCS versions 7.4 and 12.4. Following the instructions from your reply and the images, I tried to correctly link each file, particularly the csl5502.lib and various "include" folders. However, the problem seems unresolved. I have tried reinstalling different versions of CCS, but to no avail. Attached are the relevant configuration images. Is there anything else I could try to resolve this issue?

Best regards,

Hi Jun-Ting,

Here are my settings for the gpt3 under CCS 10.4.0:

I noticed that your "include library file or command file as input" is incorrect. Only the library names here, No path names.

I was able to import /build (CCS 3.3) the mcbsp1 with the following changes:

Hi Ming-Wei,

I apologize for the confusion; I couldn't quite discern the differences between the two sets of images you provided. Could you please share your variable settings? I'm having trouble finding a "library" folder and files in the XDAIS_7_24_00_04 directory, so I tried adding the folder containing csl5502.lib to the variable fields based on the error messages, but it seems to have no effect.

Additionally, I'd like to report something else. I found that if I do not specify the C5502 and USB2xx debug probe, and instead use a Custom C5500 Device, the Error I mentioned does not occur, but Warnings appear instead.

Thank you for your assistance!

Best regards,

Jun Ting

Hi Jun-Ting,

1. The first set of images are for the gpt3 project build. The second set of images are for the mcbsp1 project. I am not sure what variable settings you were asking for

2. the warnings are fine. It basically saying there those sections are not specified in the inker command file, so the linker will assign them to the default memory locations.

Best regards,

Ming

Hi Ming-Wei,

Following your suggestion, I attempted to modify the paths in the Include options and File search paths, but I am unsure if these specific paths align with yours. I believe I need the paths for the following variables:

COM_TI_XDAIS_CG_ROOT
COM_TI_XDAIS_CG_INCLUDE_PATH
COM_TI_XDAIS_LIBRARIES
COM_TI_XDAIS_LIBRARY_PATH

Here are my path variables:

Thank you for your guidance!

Hi Jun-Ting,

There are two changes needed (both showed in my above screen captures):

1. From ${C5500_CSL_CG_ROOT}/include to C:\ti\C55xxCSL\include (for compiler)

2. From ${C5500_CSL_CG_ROOT}/lib to C:\ti\C55xxCSL\lib (for Linker)

Assuming your CSL is installed at C:\ti\C55xxCSL

Best regards,

Ming

Hi Ming-Wei,

Thank you for your guidance. I deleted all projects and re-imported mcbsp1, making only the two path changes you suggested. I am pleased to inform you that I was able to build successfully.

However, I am now encountering two types of errors when I press "debug" in CCS:

An error while executing [please attach the screenshot here], followed by a "Trouble reading memory" issue when I press "continue".
An "Error -1143" appears right after establishing a debug session.

Could you please provide your insight on these issues?

Best regards,

Hi Jun-Ting,

The error message above is the GEL file c5502.gel line 202 which is part of the Init_CE0_SDRAM_5502CPUBoard() for EMIF initialization. Do you have external memory connected to the EMIF? If not, you can comment out the following lines from OnTargetConnect and OnReset:

Init_CE1_SBSRAM_5502CPUBoard();
Init_CE0_SDRAM_5502CPUBoard();

Best regards,

Hi Ming-Wei,

I have finally discussed the issue with the hardware provider. The main reason for the "Trouble Reading/Write memory problem" is that the "Watchdog Timer" on the customized board performed a hardware initialization on the DSP board.
Thank you for your assistance!
