Hi I'm studying with FRDM-KV31F EVM Board.
After I updated bootloader in OpenSDA Bootloader mode, EVM worked only OpenSDA Bootloader mode.
So i have tried to update bootloader several times.
Finally, My EVM seems doesn't work any more and BOOTLOADER drive disappeared in host PC's file system.
How can i recover my EVM board with PEmicro's 'Multilink Universal' device ?
