Error in Validation on target

[THarn]

Hello,

I flashed my STM32F4-Discovery. If I want to validate on target I get the following error:

"ERROR: no connected board(s) or invalid firmware or the board should be re-started"

I think my error comes up with the firmware, but how can I solve it?

Best regards

Tim

Hi Tim,

After building and flashing the "Validation" project onto your STM32F4-Discovery board, are you able to see some output in a serial terminal application (e.g. TeraTerm)?

If not, please check you project is correctly configured with the correct UART pins and correctly programmed.

If yes, you might have another program using the com port instance. Close any opened serial terminal applications.

More information can be found in Section "10.5.1 Error: no connected board, invalid firmware, or board restart needed" of the X-CUBE-AI User Manual (UM2526): https://www.st.com/resource/en/user_manual/dm00570145.pdf

Best regards,

Guillaume
