UEFI ARM Linux boot
by Wenwei Weng
For the last few days, I have been working on switching u-boot based bootloader to UEFI based boot loader for a new platform at work. I found out it is useful to able to boot manually with kernel, dtb, initramfs. By doing this, if the thing doesn’t work, we can change any one of them to identify which one has issue.
First you need prepare kernel image as “Image” format, device tree blob (dtb file), and initramfs.
- Linux kernel image: The Linux Kernel (linux>=3.3) supports EFISTUB (EFI BOOT STUB) booting. This feature allows EFI firmware to load the kernel as an EFI executable from EFI shell. The option is enabled by default on Arch Linux kernels or can be activated by setting CONFIG_EFI_STUB=y in the Kernel configuration.
- Make an initramfs file in cpio.gz format.
- Build a dtb file from DTS file using "dtc": e.g. dtc -O dtb -I dts -o myboard.dtb myboard.dts
When all three images are ready, and loaded them into USB pendrive, which needs to be in FAT file system.
Cautions: The board needs to have UEFI boot loader image flashed in SPI flash.
- If it is running u-boot, then the bootloader image (ATF + UEFI shell + any UEFI Applications) can be burn into SPI flash using u-boot command "bubt". Typically you want to first verify the new UEFI bootloader is working ok before burn into flash, this can be done by running from DRAM, here is an example: (*.fd file is UEFI binary to run, *.bin is ATF+UEFI binary)
- If it is running an old version UEFI boot loader and needs to be upgraded, using "fupdate" command.
