Hmm, could you send me the output of your debug build ?

The fact, it does not go into the boot manager looks strange to me.

 

Thanks,

Olivier

Hi Olivier,

 

UEFI booted properly and also detecting FAT partition I made on SD card,
where zImage is present. At boot time it doesn't ask any boot options,
instead it goes directly to EBL prompt. I have taken FAT partition path
using command 'devicepaths' and copied in dsc file as 

 

gArmPlatformTokenSpaceGuid.PcdDefaultBootDevicePath|L"VenHw(3A02E7FE-0649-4F
B4-BE4F-A862CA1872A9)/HD(1,MBR,0x13883578,0x2800,0x1DAA400)/zImage"

 

But, UEFI is not booting zImage. Do I need to do anything else or any
command is there in EBL which can boot zImage.

Thanks and Regards,

Shiva.

Hi Shiva,

Could you tell a bit more about 'But, UEFI is not even checking zImage
presented in the partition.' ?

One common mistake is a misspell error in the device path. One way to check
it is to start EBL and type the command 'devicepath'. It will print all the
EFI Device Paths expose by your UEFI firmware.

Olivier

Hi,

 

I am working on some samsung board, I am new to this UEFI. I got the FD of
the image and I am trying run UEFI on the board.

UEFI is getting started without any problem. I am getting directly EBL shell
prompt. Now, I need to boot linux kernel on that.

 

Meanwhile, I created FAT partition on SD card and UEFI is detecting that. I
have added below line in dsc file.

 

gArmPlatformTokenSpaceGuid.PcdDefaultBootDevicePath|L"VenHw(3A02E7FE-0649-4F
B4-BE4F-A862CA1872A9)/HD(1,MBR,0x13883578,0x2800,0x1DAA400)/zImage"

 

But, UEFI is not even checking zImage presented in the partition.

Please any one tell me how to go ahead after this.

Shiva.
