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.

And the stand-alone updater V3J5M2

I have the same problem, I don't know if it relates to any update.

OpenOCD from within STM32CubeIDE works.

@Nawres GHARBI @Imen DAHMEN @Amel NASRI as this seems to be a recurrent issue can we get a review/feedback as to whether this problem has been identified or reproduced.

Sorry, I gave up.

I have other things to do (just taken delivery of a new laser-cutter 🙂 and I'll come back to this some time next year. Perhaps there'll have been an update by then.

Just a reminder that the stand-alone update tool is V3J5 already (+1 month)

Maybe useful to mention that in my case, the problem seems to be intermittent and hard to track down; it could be tied to a specific binary or size of binary. Now that I developed more code, I'm not able to reproduce it anymore.

Same here, everything worked fine with STM32CubeIDE originally installed on mojave and a few weeks ago upgraded to 1.1.0 on macOS catalina. Was working fine even today, uploaded/debugged multiple times, up until the point where it forced me to update the firmware of the stlink-v2 and after that the problems started.

Error: Data mismatch found at address 0x08000188 (byte = 0x00 instead of 0xFF)

Error: Download verification failed

Downgraded the firmware to to V2J33S7 using an older st-link utility which I had installed in the vm, but then cubeIDE on OSX insists again on upgrading to V2J34S7

Downloaded stsw utility which can upgrade to an even newer version V2J35S7, but the above errors when debugging remain.

Accessing, clear, write/verify using stm3cubeprogrammer works fine within a vmware virtual machine.

Installed stm32cubeide 1.1.0 in the windows-VM and it also works, without any problems on stlink-v2 with fw V2J35S7...

stm32cubeIde on macOS seems to be unusable/broken now.

Disappointing, because I actually liked it (while it worked).

Note: Stm32cubeprogrammer also doesn't work under osx, there's other posts in the forum reporting on that, something with java - gave up on getting that to work.

Just in case people are still having problems. I've bypassed the problem by using OpenOCD on my mac. To use OpenOCD, you could refer to my example repo below

https://github.com/mofosyne/stm32h7xx-cubemx-makefile-openocd-gdbgui-example

This may not work for those who need to use an IDE, but if you are in a bind. This may help.

To program `make swd`

To debug with gdbgui `make swd-gdbgui`

To see the commands I used for `make swd` check https://github.com/mofosyne/stm32h7xx-cubemx-makefile-openocd-gdbgui-example/blob/master/Makefile#L214

Feel free to poke me if you have any issues.

Brian Khuu · ‎2019-12-03

Also take note that in Spaced Cowboy's thread, two individuals was able to switch their IDE to use OpenOCD, so you can use that option as well.

> Hey, I had the same issue and resolved it by setting Debug Configurations -> Debugger -> Debug probe = ST-LINK (OpenOCD)

> I can confirm: changing `ST-LINK (ST-LINK GBD server)` to -> `ST-LINK (OpenOCD)` does work!!!
