21 years agoHi everyone,
I have nearly the same problems that cybdenw posted. But my design is not using the boot_loader_epcs_bit.s. It uses the boot_loader_cfi.s instead (the reset-address points to flash at 0x0). The software works fine when downloaded directly. But when I use the flash in combination with the bootloader it seems that the program-counter is not set up to the right ram-address after the program-code is transfered to sdram. After system-reset nothing is excecuted, but when I reset the cpu manually after system-reset, the program executes as expected. So, could it be that there is the same error in the cfi-boot-loader, too?
