Hello friend, I'm new here but I might give you some light of your problem. I tried to do the reverse, use on fresh SD CARD. What I did was:
dd if=boot0_sdcard.fex of=/dev/sdd seek=8 bs=1024 dd if=boot1_sdcard.fex of=/dev/sdd seek=19096 bs=1024 This was for sun6i, Allwinner A31. When I compiled the Kernel (lichee) it compiled boot0_sdcard.fex and boot1_sdcard.fex, also for boot0 and boot1 for NAND. Those parts are on GPT area (see here: http://en.wikipedia.org/wiki/GUID_Partition_Table). >From what I understand (I might be mistaken), they are not "partitions", boot0 and boot1. After them comes U-BOOT. Look here (it is in portuguese but you can get the meaning): http://meiradarocha.jor.br/news/2013/05/02/como-fazer-backup-do-sistema-android-do-tablet-bc1003-wei-wide-pro-10/?replytocom=8118#respond I tried without success to place u-boot after boot1, but I manage to solve my problem using the PhoenixCard software from Allwinner to create a SD CARD from my image file. This program placed every file and partition where it should be. Sorry I didn't gave you the solution, but I hope those websites can help you find the solution... By the way, I'm with problem on my SD CARD. You said you did manage to load with success. Mine is with problem trying to find the NAND partiton. My original image file was made to work with NAND Flash, but the project I'm trying to do demands SD CARD. So I removed my NAND and I'm trying to load everything from SD CARD. My kernel tries to find the NAND partitions that don't exist anymore. Do you know where I can change these before compiling my Kernel? Thanks, Igor.
