Hi
I am downloading my application using LPC2000 v2.2.1 on to lpc2138 board with flash 512k.And insted of deleting entire device(flash) i am selecting particular sectors to be deleted(for example 0-14)but it is not allowing me to do and it is throwing an error "cannot communicate with test board" and at the down it is displaying "lpc2000 flash erase failed".
Please suggest me how to solve this problem
Thanks Reddy
ok and now code read protection is enabled by programming the flash adress location 0x1fc(sector 0) with value 0x87654321.
Who writes this value to flash initially ? How do I re program to remove this one permenantly?
