Did you set the jumpers for DFU mode?
I find DFU mode easier.

When I try to flash bootloader (taken from this Github), I receive the same verification errors as during flashing the firmware. image.png (view on web) https://github.com/FYSETC/FYSETC-SPIDER/assets/128132691/e7383403-434d-4d40-8fb2-b2c4df453e42
How can I finally flash my MCU?
