Hi everyone, I have Ender 3 Pro and recently i have gotten a new BIGTHREE SKR 1.4 TURBO ,After firmware flash changing some configuration options in Marlin the borad seems to be dead.
The SKR 1.4 doesn’t show up in my Device Manager on Windows and the bootloader also doesn’t flash/load the binary from the Sd card.
After searching and reading few articles I mange to connect to the board via OpenOCD using STLink and this is the result :

I tried to program the chip but i got this error :

Warn : Boot verification checksum in image (0x00000000) to be written to flash is different from calculated vector checksum (0xeffc285a).
Warn : OpenOCD will write the correct checksum. To remove this warning modify build tools on developer PC to inject correct LPC vector checksum.

Appreciate all the help, thanks!
