Hi sir

i able to build U-boot and kernel source codes with cross compiler,
after that what are needed for sd boot. (i cant understand here the process)
could you please send the customising SD card booting documentation to my Mail.
and suggest preferable U-Boot, Kernel and cross compiler.


@harish, In that case, please feel free to use the Monthly and Weekly generated images that are linked from here:

The Monthly images are based on Debian Stretch (9.x):

While the Weekly images are based on Debian Buster (10.x):

Use to write the *.img.xz to a microSD card…
