Remote update controller issue

Hi everyone, I'm using the remote update controller (cyclone III) on my Cyclone IV GX dev board with a EPCS128 flash memory. I wish to have two firmwares in my EPCS (factory and application)....

Hello,

I've tried to implement the new bootloader on a Cyclone IV and I found a bug in "boot_loader_epcs_bits_sii_siii_ciii.S" writed by hallodu.

To have a full compatibility with all address you must write this code before "fp_short_circuit:" label:

movhi r24, %hi(IMAGE_START)

add r_flash_ptr, r_flash_ptr, r24

//orhi r_flash_ptr, r_flash_ptr, %hi(IMAGE_START)

best regards
