STLINK-V3MINI is not doing the full erasing the memory in the second programming cycle. In the test system, we have two steps of full erase the flash memory. In the first it works well, but in the second it isn't able to do the flash erase.

After this second trial, the only way that I'm able to program the MCU is using the JLINK, but I would really need the STLINK-V3MINI working as expect.

Hello @RBitt.1​ 

Are you able to test is with a STLINK V2 ? Can you give me the version of STMCubeProgrammer you are using ( STM32_Programmer_CLI.exe -version) ?

[RBitt.1]

Hi Bruno,

tested with STLINKv2 -> same issue

Cube updated to 2.10.0, tested with 2.9 as well, same issue.

Hi Bruno,

Is there any news/suggestion to test?

Thank you!

As always - use "connect under reset" and "hardware reset" modes.

Ciao @RBitt.1​ 

Sorry about the delay, it took me some time to find a STMF board.

I confirm that the right way to program is to execute the following command :

STM32_Programmer_CLI.exe -c port=SWD mode=UR -d <file_to_program> -ob rdp=0xBB

That should download the file and lock the device in RDP level 1. If you want to verify the download just, add -v just before -ob.

To unlock the part, (mass erase will be performed automatically), execute

STM32_Programmer_CLI.exe -c port=SWD mode=UR -ob rdp=0xAA

Is it ok for you ?

BR,

Bruno
