Hi Hui Ma,

Yes, it is same version with your board version 700-27556 Rev A1 and Sch-27556 Rev F.

Now we can get 6 files after copy MSD-FRDM-KL25Z_Pemicro_v105.SDA this file into bootloader disk, after this we copy blinky_blue.srec into disk, then unplug USB, again plug usb to PC, but only see board LED D4 light green, D3 not light blue, that is the problem, we are not sure if the board already damaged or not? Please help clarify this or if can repair it.

I don't find your mentioned issue on my site. The D3 was blinked with blue light (blinky_blue.srec).

Could you using scope to check if the KL25's PTD1 pin with period GPIO toggle signals?

You also could probe at TP17 (test point).

Wish it helps.
