dspic33f bootloaded firmware not working - tester - 2014-02-12
Hi there,
I have a hardware at hand, which i want to implement a bootloader. I modified the ds30 bootloader and flashed it to my microcontroller(dspic33f64mc710). then, i used the gui in order to flash my firmware to my microcontroller. everthing is fine to this point. gui verified that there is a bootloader, it flashed the firmware and verified. Everything seems ok. Then closed gui and open a terminal software and send a command to my hardware, there is no reply from hardware. Normally, it should replay with an answer. When i load the firware without bootloader, it works normally and answers to my command. I have a led on the hardware which is working normaly in either case. so, i suspect that there is a problem with uart. both bootloader and my firware uses same uart (uart1). I think there should not be any problem. any insights?

Hi,
Are you using the application config bits and oscillator configuration in the boot loader?
