I know this topic has been revised over and over, but still cant make it work.
Im usin mcuXpresso IDE.
Board was working fine until some code i made seem to broke it.
When trying to debug the board, it appears this message:
0 available SWD Devices detected.
Connect a device and try again.
Ive tried changing the K20 bootloader on the on the board. Tried openSDA 2.2 and also DAPLINK. None of them worked.
Also tried Mass Erase option from the GUI Flash Tool and Ressurect Locked Device. Both options returned with error.
Please find attached the console when tried the Ressurect Locked Device action.
Is there anything i can make without using another board/programmer to program it? Maybe a flash erase by using some combination of jumpers?
