Hello all,
I'm learning about u-boot these days and have a basic question about mkimage.
I saw in a pdf document (opdenacker ) this command.
mkimage -A arm -O linux -C none -T kernel \
-a 0x20008000 -e 0x20008000 \
-n "Linux-5.12.6" \
-d arch/arm/boot/zImage arch/arm/boot/uImage
1. It looks like I am supposed to run this command in the linux source director not u-boot source directory. Is it correct?
2. And in linux, by running make uImage, I can make uImage under arch/arm/boot/, buy why should we use this mkimage command?
(I'm working on arm64 so I don't need uImage and I just run 'make Image')
3. I found I can install mkimage on ubuntu by 'sudo apt install u-boot-tools' but also found mkimage is compiled under tools (in u-boot).
Then am I supposed to include the tools directory to PATH and use that version?
If anyone knows a good hands-on tutorial about u-boot (from kernel, initrd, dtb build to u-boot build and use. hopefully for arm64. I'm hope for too much..), please share it here.
Thank you!
