Thanks for the info.I have tftp and tried netboot.After uploading kernel, dt and init-ram-disk into ram in boot stage boots says "wrong image". I thought maybe init ram disk image is not ready for imx yet. Now that you're saying it should work, I'll investigate further to find problem.Another question is: when NBD push the ext4 rootfs, supposed everything working, how can we debug? I mean with the nfs we actually had a folder on our host and we could install and debug app with at or.... , But now what could we do with just a *.ext4 that NBD is serving to Target ?Thank you for your supportVahidOn Tue, Oct 1, 2019, 00:26 Stephane Desneux <stephane.desneux@xxxxxxx> wrote:Exactly.
And even if there's no TFTP (or no ethernet driver in uboot), it's still
possible to cheat: for example, you can build with agl-netboot feature and
you'll get a kernel image, a dtb, an initramfs and a rootfs. You can put
everything but the rootfs on a sdcard and boot from it 'as usual' then let the
initramfs mount the rootfs through NBD: set the nbd.xxx variables accordingly in
the kernel command line and don't forget to serve your rootfs ext4 file with a
nbd server).
Please keep us posted on your progress: I'm sure many people would be interested
with this netboot feature :)
