I use lpc2378 and can write to flash with IAP, but if I have working ethernet (based on easyweb sample) then... then a number of things occure exept normal work.
Anybody uses write data to flash with ethernet ?
Be sure that you are disabling interrupts before you call an IAP function.
ups.... right text should be Be sure that you are disabling interrupts not with __diable_irq() before you call an IAP function.
