I am using a secondary Ethernet boot loader for lpc1769.My bootloader located at 0x0 and it uses a first three sectors.Remaining sectors in flash are used for application code. When I am downloading application code for led blinking using timer in interrupt it is working fine. During the timer interrupt, execution comes in the timer isr in bootloader, from where I relocate to the application timer isr. It is working perfectly.
The problem occurs when I downloading the led blinking program using uart interrupt. While interrupting the uart execution doesn't come in the bootloader uart isr. so that I couldn't able to relocate the bootloader isr to application uart isr.
What cold be the problem? please help me to solve this problem.
