Hi Bin,
If you can have a look at this issue.
I am currently stuck on this issue with u-boot.rom not giving me any output on the serial.
When I am flashing MinnowBoard.MAX.X64.080.D01.bin I get the all the UEFI prompt and the booting messages but when I flash u-boot.rom, I do not get anything on the serial port.
Let me know if I am missing out something in the build process of u-boot.rom
While running the following commands, I seem to get the errors-
c) ./tools/ifdtool -x BayleyBay/SPI.bin 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
AND
a)./tools/ifdtool -x MNW2MAX1.X64.0073.R02.1409160934.bin 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
These may be the reason for the u-boot.rom not getting built properly.
I have described the entire build process for u-boot.rom int my previous mail below -
I am building u-boot.rom for MinnowboardMax as per the steps mentioned in the README.x86.
- Downloading BAY_TRAIL_FSP_KIT_GOLD3.tgz
a) copying BAYTRAIL_FSP_GOLD_003_16-SEP-2014.fd as board/intel/minnowmax/fsp.bin
b) copying Vga.dat as board/intel/minnowmax/vga.bin
c) ./tools/ifdtool -x BayleyBay/SPI.bin
From the generted files, copying flashregion_2_intel_me.bin as board/intel/minnowmax/me.bin
Though the o/p files are generated, I get the following error after this command - 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
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/

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

- Building u-boot.rom
export BUILD_ROM=y make minnowmax_defconfig make all
Looks that your instructions are correct according to README.x86
- 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?
- 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.
Regards, Bin
