Error during flashing with STM32_Programmer_CLI.exe, and how to fix it.

ADiet.1 · ‎2023-03-14

On windows 10 I am using STM32_Programmer_CLI.exe (2.13.0) to flash bytes to memory using the following command line

but then I do so I get a very strange output:

ST-LINK SN  : 53FF71065056705420540981
ST-LINK FW  : V2J29S7

Now has the flash succeeded or not? Because I get an error and then some green bars. How to get rid of this error?

Also, the command did NOT succeed. Checking with the UI version of the programmer at least I see that the address 0x08080000 has not been changed. How to fix this problem?

Hello @ADiet.1 ,

The part number is written on top of the MCU as shown in the picture below. Please check your board and send it to me.

The device that you referred to in your last comment is the STLink-V2 and it is a debugger and a programmer.

About the binary file, you can send it to me in private.

Thanks in advance,

Sara.

Ah I see, - I cannot see that anymore as the chip is built into a housing. It is impossible to get this number. But as far as I know it is of type STM32L071.
