Hi NXPs,
Refer to AN10995 LPC1100 secondary bootloader(http://www.nxp.com/documents/application_note/AN10995.zip)
Using NVIC_SystemReset() to return secondary bootloader from user application code.
Are there any other way to do this?
I use LPC1114 for power control in design(LPC1114 will power on our master cpu via GPIO, LPC1114 is connected gpio and uart pin with our master cpu)
If we want to upgrade LPC1114 application firmware via  uart command from master cpu. In such case, LPC1114 should not be reset because it will cause power off our master cpu.
How could I do ?
Thanks!

Best regards,
Steven
