Dear FreedomK64,

 

 

I think the bootloader on the K20 (debugger chip) is corrupted.

I would reflash that bootloader so I can restore the drag and drop capability.

 

I found  DEBUG-FRDM-K64F_Pemicro_v108.S19 in the following KDS folder and reflashed the K20 with it but it still doesn't work.

C:\Freescale\KDS_1.1.1\pemicro\opensda

 

Regards,

 

hy

Hy,

The mbed bootloader does not take srec. Please refer to FRDM-K64F QSG. The openSDA firmware you found in KDS is only for P&E bootloader.

When you hold the reset and POR, is the board able to go into bootloader mode? A "bootloader" label will show up in windows file explorer.

Regards,

TsiChung
