Hi ,

I was debugging a SDRAM test application on my board from LPCXpresso v7.9.2 and found some issues with code. Stopped the current debug session and when started the next session, all of sudden I am not able to download code to micro. Until the problem occurred I was able to debug completely.


I get below errors
