STM32CubeIDE updated stlink on a stm32H743-EVALv2 board to V3J4M2, but then is unable to program the board.

Brian Khuu · ‎2019-10-20

Was able to program the board previously, but today after updating my STM32CubeIDE, it refused to run debug until I updated the stlink on my dev board.

But upon doing so, it gave these error. Essentially meaning I cannot program my dev board.

I am running this IDE on a mac on MacOS catalina. Oh and btw I still cannot run latest STM32CubeProgrammer on mac, even after updating java to latest version.

Would probably edge back the speed from 24 MHz, and select most verbose logging.

Try setting the BOOT0 switch to 1-System Mode

The funny thing is Cube Programmer offers version V3J3M2 and ST Link Utility V3J4M2???

Anyway try Cube Programmer with a reduced speed.

hansd56 · ‎2019-10-20

Sorry, I should mention I have the poor man's version Nucleo-H743I2.

hansd56 · ‎2019-10-20

There is now a new option with ST Link Server to set SWD speed. Not sure how to use it with CubeIDE yet. There should really be a selection box like in CubeProgrammer.

--frequency <max freq kHz>

Specifies the ST-LINK communication frequency in kHz, such as 5, 25, 100, 240, 950, 1800, 4000, 8000,

24000 kHz.

Brian Khuu · ‎2019-10-20

Yeah there is a way to change the swd speed. Just tried 5Khz to no success... so not too sure what changed between the old version and this version of STLink

It would be nice if STM32CubeIDE allowed me to use an older version of STLink.

Okay just rediscovered the windows only stlink GUI utility STSW-LINK004 from:

https://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-programmers/stsw-link004.html

Turns out that the windows STSW-LINK004 utility works and was able to erase the board. However I was still not able to access the board from my mac using STM32CubeIDE. I wonder if it's to do with any change in stlink debug configuration between the old STM32CubeIDE and the new STM32CubeIDE.

Btw how did you get "STM32CubeProgrammer" working? I've already tried it on Mac, Linux, Windows with no luck. Is it requiring a specific java version?

Ok, going to try making a new STM32CubeIDE project to see if it's anything to do with the project migration.

Brian Khuu · ‎2019-10-21

Just created a new CubeMX project named `testproj` and kept it to all the default values and just ran it in STM32CubeMX on my mac. Still failed.

Looks like something is wrong with the inbuilt`STM32CubeProgrammer v2.2.0` in STM32CubeIDE for `stm32H743-EVALv2`. But the windows STSW-LINK004 stlink GUI utility works... so maybe windows STM32CubeIDE would work?

I think I'm running into this as well - see here

I have the same issue. With F303 Discovery and STM3240G-EVAL. Running mac os sierra and STM32CubeIDE Version: 1.1.0. Everything worked fine before updating
