FRDM-KL25Z Error : USB communication failed

[dhananjayankutt]

Hello friends,

I am using Freedom KL25Z.

The problem is when i am programming the MKL25Z128VLK4 chip using the tool CooCox CoIDE 1.7.2, i am getting the error "Flash: Flash program

failed" and following that i get "USB communication failed". I get this error continuously and i cannot flash and run it.

Please anyone suggest your ideas to overcome this problem. Thanks in advance.

Hi

I do not use Coocox however I feel you need to follow their instructions from the included link, the debugger should not be the PE-OSDA but CMSIS-DAP

http://www.coocox.org/downloadfile/CoIDE/How_to_use_OpenSDA.pdf

there is getting started package on Freescale pages (the link is on the box of your FRDM), where you can download the CMSIS-DAP.
