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.

It can't work so far, but 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
