How to use linux kernel I compiled?

I compiled newest linux kernel and uboot, but I don’t know how to boot with it, the kernel output file seems haven’t ‘zImage’.

Your Archlinux image for VIM appears to be using ‘Image’ file directly, can you help me, thanks.
@balbes150

You can use Image and command booti to bootup.

booti ${kernel_loadaddr} ${initrd_loadaddr} ${dtb_loadaddr}

But I don’t know how to enter uboot mode, I have serial tools.

You need to setup the serial.

Have you seen the output message from uart? If so you can hit any key to enter the uboot command line.

I tried, but finally enter the ubuntu

Can I modify this config to start from ‘Image’?

If the kernel is built with the text_ofset patch, you can simply rename the Image to zImage.

Does it mean I’m in the uboot console?

I compared ‘Image’ and ‘zImage’, they have same header info.

Yes. It is. You are in uboot console.

@numbqq

It seems need a ‘zImage’
And I want to know how to get uInitrd, I copy it from another image, is that right?

You can simply rename Image to zImage. But you need text_ofset patch for mainline kernel as @balbes150 said above.

Thank you, I’ll have a try

Could you provide a config file for linux5.x?

Are you sure that you applied the patch successfully?

Yes, I’m trying to use another config to compile now

What a mess you have in eMMC ? Restore the regular firmware Android and only after that try running your version of the kernel with external media.
