Dear Memers, i started a new project with LPC1769. I bought a LPCExpresso LPC1769 Rev c  with based board from element 14(farnell)
OM13000 DEV BOARD, LPCXPRESSO, LPC1769             : OM13000
I am using LPCexpresso as my IDE and compiler with FRee RTOS
I import demo1 application which can build without any error, when try down load this application i got the following messa
