How to debug flash download via CMSIS-DAP?
Dear sirs, I have one KL25Z chipset, and I know it can be upgraded firmware via mass storage or SWD by Keil because of CMSIS-DAP. Now I want to rework mk20d connected to other cm4 mcu, and rewrite the flash algorithm in CMSIS-DAP source code. But it can't work so far, and I don't know where the problem is, maybe flash algorithm or hardware setting. so could you please tell me how to debug this operation?
Best regards, Andy
