I'm using HC912B32 EVB, I need to program to use the IRQ interrupt.
But I can't program the EEPROM to point the IRQ interrupt vector to
my IRQ isr (in EVB mode). Is it that using bootloader to program the
EEPROM is the only way I can do this. I've never tried with the
bootloader n find that its procedure is quite troublesome. If
bootloader is a must, is there any tool I can do this easefully?!
