hello, i successfully ported the fallbackimage-principle for the elitegroup p6stp-fl (sis630)but the problem is that it only works with 64KB fallback-image (i took the calculations from "supermicro/p4dpeg2/Config")
because i need more space for the payload i need a bigger fallbackimage, but if i change the size of "FALLBACK_IMAGE_SIZE" only the fallbackimage will boot, not the normalimage (each time the normalimage should be jumped to the watchdogtimer expires and resets the board, after that the fallbackimage will boot again)
does anybody see what i made wrong? (below is a part of my config

size related stuff from my config ----------------------------------------------
option USE_FALLBACK_IMAGE=0 expr USE_NORMAL_IMAGE=!USE_FALLBACK_IMAGE
option ROM_SIZE=0x80000
#works only with exactly 0x10000, need more! <--------- option FALLBACK_IMAGE_SIZE=0x10000 option ROM_IMAGE_SIZE=43520
expr ROM_SECTION_SIZE=(USE_FALLBACK_IMAGE * FALLBACK_IMAGE_SIZE) + (USE_NORMAL_IMAGE * (ROM_SIZE - FALLBACK_IMAGE_SIZE) ) expr ROM_SECTION_OFFSET=(USE_FALLBACK_IMAGE * (ROM_SIZE - FALLBACK_IMAGE_SIZE)) + (USE_NORMAL_IMAGE * 0) expr ZKERNEL_START=(0xffffffff - ROM_SIZE + ROM_SECTION_OFFSET + 1) expr PAYLOAD_SIZE=ROM_SECTION_SIZE - ROM_IMAGE_SIZE expr _ROMBASE=ZKERNEL_START + PAYLOAD_SIZE
#cache the upper 16M of the 4G address space #or else the decompression would be so slow that #the watchdogtimer resets the board even before #decompression is done option XIP_ROM_SIZE= 0x01000000 option XIP_ROM_BASE= 0xfe000000
