Hi Bin,

Though the o/p files are generated, I get the following error after this command - root@saket-PC:# /u-boot-x86/tools/ifdtool -x MNW2MAX1.X64.0073.R02.1409160934.bin Flash Region 0 (Flash Descriptor): 00000000 - 00000fff Flash Region 1 (BIOS): 00500000 - 007fffff Flash Region 2 (Intel ME): 00001000 - 004fffff Flash Region 3 (GbE): 00000000 - 00000fff Flash Region 4 (Platform Data): 00fff000 - 00000fff (unused) Error while writing: Bad address
I've seen this error before. It is a bug of the ifdtool, but I think it can be ignored. I have a patch sent out. Please check http://patchwork.ozlabs.org/patch/478590/
Your patch fixes the Error message but still I do not get any o/p on serial with the resulting u-boot.rom
- Flashing u-boot.rom to Minnowmax by desiprog sf100
./flashrom -p dediprog -w u-boot.rom
Can you confirm that you have setup the flashrom tool correctly? I don't use flashrom on Linux as I normally do the SPI flash programming on a Windows machine. Can you dump the whole SPI flash image back after you program the u-boot.rom and compare the dumped file with the u-boot.rom you generated to see whether they are exactly the same?
I only way I have dumped SPI flash has been through flashrom only. How else can I do it on Linux?
As of now I am trying to burn u-boot.rom with SPI programmer/software on Windows to check the sanity of my flashrom setup.
- Now when I am powering Minnowmax and collecting the output on serial
Nothing appears.
Kindly let me know, if I am missing something here.
Sorry but I don't have a MinnowMax board here, so cannot try it on my side.
I'm on holiday but should be able to try this on Monday or Tuesday.
Thanks Simon.
It seems to boot OK for me. See details and download link below:
