Unable to boot kernel with UEFI on LS1012A FRWY board.

[srinidhir]

Unable to boot kernel with UEFI on LS1012A FRWY board.

I am using LS1012A FRWY device and I have partitioned SD-Card with two partitons.
1] vfat to store efi binary , dtb and grub.cfg

2]ext4 for rootfs.

When I power on the board and enter u-boot prompt, If I give the command, "run bootcmd", u-boot loads kernel 'Image' and then kernel boots up properly as expectedand I get the login prompt.

When I run command 'run scan_dev_for_efi', EFI binary executes properly and It provides grub prompt. However, If I load the same kernel 'Image' and 'dtb' as used by u-boot by using 'linux' and 'devictree' commands, Kernel is hanging during boot-up.

Kernel starts to boot and it has parsed the dtb properly. After PCI initialization etc., It disables serial console and then It tries to load UART driver. after this, the console output is not it readable format and it is also not reaching the stage where it mounts rootfs.

I am using 4.19.6 kernel, but this kernel works properly when booted directly from u-boot. I am facing this problem only with uefi-grub. I have used the efi binary which was generated from LSDK-18.09 as well as another efi binary generated from grub git source code but I am facing the same issue with both the binaries.

Thanks & Regards,

Somehow the command 'devicetree' in grub does not pass the dtb to kernel. I had to load dtb from u-boot prompt and then boot the kernel from grub prompt.

Hello SRINIDHI RAO,

In the recent released LSDK, we use different procedure to boot UEFI from you, please refer to the section "5.4.3 LSDK distro boot with UEFI Boot" in LSDK 1812, which could be downloaded from Layerscape SDK | NXP .

If you use the previous version Linux SDK, you could refer to https://community.nxp.com/docs/DOC-333443 .

Thanks,
