If you change the size (8A is 1Mb and 4B is 512KB right?) you will need to make an adjustment in the target/../config.lb in order to get the correct ROM size. option ROM_SIZE=1024*1024-36*1024 > The best way for me would have been to test it and find it out myself > but currently coreboot build is failing on Fedora 8 based system even > after applying the rececent patches and updates to LD. > I will take a closer look at the failure you sent. > I am just curious does CS5536 has to be initalized in a differently to > be able to boot from FWH ? You will need check cs5536 boot straps are set to FWH.
