Cannot flash chip after sectors erasing

[TAKSO]

Hello, I want to flash my program in STM32 chip after sectors erasing. I cannot upload my soft and I need help from you.

I tried to upload my ST-link V2 debbuger but since it seems to not work fine. Any idea ?

Thanks in advance.

Check your setup and procedures. Flashing works for many people, so probably the problem is on your side. Did you tyr with a "known-good" setup first. e.g. a nucleo board?
