[MC60]-Boot failed, reset

i am newbie with mc60. After flash file bin, I want to see how app_debug has to do, I got the following error:

Dear Sir,
Please check which bin file you have flash to module ? what is the base FW version, and the SDK FW version ? whether they are match with each other ?
By the way, please confirm which part of the SDK code you have modified, if you flash back to the standard FW, whether the module can work normally.
Please help to provide more information, then we can help you to solve the issue. Thanks!

Thank you, Mr Ky Son
