Hi Mark
I made some changes in my own link_uc3b0256.lds script and add some linker flags, but still not working.
With the changes I made in the linker script, my program is not overlapping the bootloader (only shows . during the charge and not appears !). But my application is not working. Finalize the charge of the program and the bootloader write: Starting Application, but the application seems not start. When I press PBO button in my EVK1101 board, appears the bootloader, but when I write go, occurs the same problem.
i'm using the "avr32-objcopy.exe -O srec original.elf final.srec command to convert elf file to srec
Any ideas?
Thanks in advanced.
This is my linker script:
