Error while Flashing imX95 board

Abhishek05 — Mon, 05 May 2025 09:35:11 GMT

I am using the NXP i.MX 95 Eval Kit. I have migrated a custom application to FreeRTOS. The migration is completed, and the code is compiling. But while flashing, I am getting the error [HID(W): LIBUSB_ERROR_PIPE] using uuu tool.

Wait for Known USB Device Appear...
New USB Device Attached at 2:2-A027376C1F1041DB
2:2-A027376C1F1041DB>Start Cmd:SDPS: boot -f flash.bin
49%2:2-A027376C1F1041DB>Fail HID(W): LIBUSB_ERROR_PIPE (-9)(5.698s)

For adding my custom files into project, I have used the below methods, there are around 50 files to be added to the project.

file(GLOB ADDITIONAL_SOURCES1 "${ProjDirPath}/../HLAC_Proteus/Source/*.cpp")
set(ADDITIONAL_SOURCES
${ADDITIONAL_SOURCES1}
${ADDITIONAL_SOURCES2}
${ADDITIONAL_SOURCES3}
list(APPEND ADDITIONAL_SOURCES
"${ProjDirPath}/../freertos_hello.cpp"
"${ProjDirPath}/../board.h"
"${ProjDirPath}/../board.cpp"
"${ProjDirPath}/../hal_config.h"
"${ProjDirPath}/../clock_config.h"
"${ProjDirPath}/../clock_config.cpp"
"${ProjDirPath}/../pin_mux.cpp"
"${ProjDirPath}/../pin_mux.h"
"${ProjDirPath}/../hardware_init.cpp"
"${ProjDirPath}/../app.h"
"${ProjDirPath}/../FreeRTOSConfig_Gen.h"
"${ProjDirPath}/../mcux_config.h"
)
If not using the additional files, the bin file is flashing, but with this additional file the code is compiling but not flashing on the board.
Please Help

Hello,

We do not have documentation regarding FreeRTOS porting. I strongly suggest you confirm the steps you are following with software provider, here some steps you can use to troubleshoot and solve your issue:

- Update UUU to the last version.

- Verify the files paths of additional software added.

- Add additional files incrementally to verify what could be causing the issue.

Best regards.

Hello JorgeCas,
1. Which is the latest version of UUU? If uuu is fine, as basic hello world programs are running fine.
2. Additional paths are perfect.
3. I can't add additional files incrementally, as all files are interdependent. So all files need to be there for proper compilation.
For normal FreeRTOS Hello World Code M7 partition size is
22528 bytes (23 kB, 22 KiB) copied, 0.000158571 s, 142 MB/s
42+1 records in
42+1 records out
21844 bytes (22 kB, 21 KiB) copied, 0.000219649 s, 99.4 MB/s
M7 file_offset = 0xbbc00 size = 0x5800

For my Application, when compiled and made flash.bin M7 partition is
604160 bytes (604 kB, 590 KiB) copied, 0.00161078 s, 375 MB/s
1179+1 records in
1179+1 records out
603808 bytes (604 kB, 590 KiB) copied, 0.00341523 s, 177 MB/s
M7 file_offset = 0xbbc00 size = 0x93800

Are there some restrictions here?

Re: Error while Flashing imX95 board

JorgeCas — Wed, 07 May 2025 18:52:26 GMT

Hello,

1. The latest UUU version is uuu_1.5.201.

2. Got it.

3. There is not a limitation in file size, but I suggest you check with software provider.

Could you please share the UUU command/script you are using?

Best regards

1. Got it Thanks. I am using this on only
3. uuu -b sd flash.bin

Hello,

I asked internally and this issue is caused by TCM space dedicated to Cortex-M, which is 256 kB / 512 kB.

Your application exceeds this limit.

Best regards.

Re: Error while Flashing imX95 board

Abhishek05 — Tue, 13 May 2025 16:43:23 GMT

Thanks a lot for your help. Is there any way to increase this limit?
Also one more thing how you concluded that my application exceeds this limit? By which parameter you judged it ?

Re: Error while Flashing imX95 board

JorgeCas — Tue, 13 May 2025 18:48:48 GMT

Hello,

This memory cannot be increased.

This can be verified in table 1 "Arm Cortex-M33 and Cortex-M7 platform" of datasheet.

Best regards.

Thanks a lot for letting me know this.
I just want to know how did you infer this issue from below data
604160 bytes (604 kB, 590 KiB) copied, 0.00161078 s, 375 MB/s
1179+1 records in
1179+1 records out
603808 bytes (604 kB, 590 KiB) copied, 0.00341523 s, 177 MB/s
M7 file_offset = 0xbbc00 size = 0x93800
or any other method you used to infer this. As i need to document this thing.
Thanks

Re: Error while Flashing imX95 board

JorgeCas — Wed, 14 May 2025 18:58:29 GMT

Hello,

I just inferred this by the size of your application. We saw a similar issue in an i.MX93 but it is limited to 256K in that case.

Best regards.

Hello,
Got it thanks a lot. Is there any way to resolve the issue? I cant reduce the size of application in my case?
Thanks

Re: Error while Flashing imX95 board

JorgeCas — Mon, 19 May 2025 18:49:46 GMT

Hello,

Since it is not possible to expand this capacity, I suggest you take a look in optimization side for your application.

Best regards.
