[avr-chat] need help on avr-libv and winavr

[Carlo Ossanna]

Hello,

 

I am using winavr 20100110 on an atmega128 and I need to do the following :

 

1. put the interrupt vector table (including reset vector) to the base address of the boot loader section (i can define that base value with fuses)
2. The Boot section brings control after reset
3. have my application code starting at 0x0000 launched after reset by the boot loader section
4. allocate all the application ISR functions starting at the base address of the RWW section.
5. All these ISRs must be linked to the interrupt vetor table at point 1.
6. Allocate some code to update the internal flash in RWW section and call it from the application section

 

The reason of my request is to be able to execute code called from the application section to write the internal flash memory having all the interruptus working during flash update.

 

Do you think this is possibile using avr-libc and winavr ?

Could you help me ?

 

Thanks for your kimd attention,

 

Best regards,
