I have a st32f407vet6 card that I was connected to with the st link utility, but then when I connected with the st cube programmer, the card was blocked. Please help how to unblock

It would help if you can provide more information. I don't believe a simple connection of the board to the cube programmer IDE could harm or block it, unless you did modify some parameters especially the option bytes...Is this the case here? and if so could you detail the steps you followed in order to help you unblock the board?

Also it will be good if you can precise what kind of message error you receive when connecting the board ( like is target not detected or halted etc...)

Hi Imen,

I use ST_Link V2 for programming an debuging. So you can use STMCubeIDE or IAR to communicate with the VET6.

In configuration select ST-Link V2, SWD mode and not JTAG mode.

Hope this will help.

Blocked? Bricked?

Do you connect NRST pin? Needed for "Connect Under Reset"

Can you connect with BOOT0 pulled HIGH?
