I am following the application "AN11782 LPC82x UART secondary bootloader" to build the secondary bootloader to LPC824.
If you compile the bootloader example and debug using lpcxpresso, its working well.
Even i terminate, power off and on the device, it can still working.
However, the chip is not working if i load the hex file to the chip using flash magic.
Please see if anyone has met this case before and give advise
