Programming to external flash on STM32U5A9J-DK fails after around 2.5 MByte. How to fix this?

[JWill.11]

I'm using a STM32U5A9J-DK with TouchGFX. Smaller projects work just fine. But aufter integrating an Animated Image (approx. 37 MBytes of assets), the programming fails. The console log is as follows:

In the debug configuration, following external loader is specified:

MX25LM51245G_STM32U599J-DK.stldr

I tried to read out the memory using a J-Link with the JMem tool. There, I noticed, that after around 2.5 MByte, the content is filled with FFFF... The external flash should have 64 MByte.

Is there a way to fix this issue?

The memory location, where it stops flashing, is always the same (0x9026 BC00).

Hello @JWill.11​ ,

Thank you for reporting this issue.

I confirm the issue: External memory programming failed using a file with size bigger than 2.4MB using STM32CubeProgrammer v2.13.0.

Hi @JWill.11​ ,

Waiting for the next STM32Cubeprogrammer release, could you please use the STM32CubeProgrammer v2.12.0 version and check if the issue is solved.

I hope this help you!

Thanks. Can you provide me with a link to this version, as through the official ST page, one can't download version 2.11 and 2.12.

[JWill.11 · Accepted solution]

I tried version 2.10 of the STM32CubeProgrammer, which worked now.

Hi @JWill.11​ ,

Glad to know that the issue is already fixed.

I will let you know when the issue is fixed in the next version.

Sorry for this inconvenience.

I use TouchGFX 4.22.0 to generate the UI code, use STM32CubeIDE 1.13.0 STM32CubeProgrammer v2.14.0 to flash my program into STM32u5a9j-dk, the issue still exists.

How did you switch back to STM32CubeProgrammer v2.10 from v2.13? Thanks.
