STM32L476 Error: failed to download Segment[0]

[HLi.1047]

Hi

I'm using Atollic TrueSTUDIO® for STM32, Built on Eclipse Neon.1a. Version: 9.3.0 Build id: 20190212-0734

I get the following error when I try to debug:

everything was fine before I wrote a few extra functions that pushed from 127 sectors into 128 sectors.

Here is the 127 sector message shows that it was fine before:

STM32 ST-LINK Utility loaded the same bin file without error.

The STM32L476 should have 1MB flash, and I've used just over1/4 of it.

I was using no optimization (-O0) when the error occurs. And I have confirmed that with the same code, if I optimize for size (-Os) then the error goes away.

Eventually, my code size will grow and hit this error again.

Please help me get over this limit.

Cheers

Harry

Hello @HLi.1047​ ,

Try to upgrade firmware version using STM32 ST-LINK Utility: go to ST-LINK>firmware update,

 Then disconnect and connect your board.

I also advise you to update the STM32Cubeprogrammer and use the latest release.

Keep us informed about your update.

Hi​ Imen

Thank you so much. Your instructions fixed it.

STM32 ST-LINK Utility showed that I had:

STM32+STM8 Debugger

V2.J37.S7

I reflashed my st-link V2 even though it was the newest firmware.

Then download the newest STM32CubeProgrammer 2.10, installed it, and followed the following instructions to integrate it into TrueStudio:

https://www.st.com/resource/en/application_note/an1801_stm32cubeprogrammer_in_truestudio-installing-stm32cubeprogrammer-in-truestudio-stmicroelectronics.pdf

I had:

STM32CubeProgrammer v1.3.0  

Which is very old, I assume it came with TrueStudio, because I never integrated into TrueStudio.

Then everything just worked without optimization.

Cheers

Harry
