Hi Bin,
Please find my response inline.
root@saket-HP-PC:# /u-boot-x86/tools/ifdtool -x BayleyBay/SPI.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): 00fff000 - 00000fff (unused) Error while writing: Bad address Flash Region 4 (Platform Data): 00fff000 - 00000fff (unused) Error while writing: Bad address
a)./tools/ifdtool -x MNW2MAX1.X64.0073.R02.1409160934.bin From the generted files, copying flashregion_0_flashdescriptor.bin as board/intel/minnowmax/descriptor.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.
