532910 Posted June 27, 2017 Posted June 27, 2017 Am I right, that there are no wifi support at uboot level for sunxi boards? And the only similar solution to use wifi at early level is to boot linux kernel with wifi support from SPI flash.

No support for any board. 2 minutes ago, &ergio said: And the only similar solution to use wifi at early level is to boot linux kernel with wifi support from SPI flash. Only kernel is not enough, you'll need userspace programs like wpa_supplicant (and a lot of shared libraries that they depend on) if you want to connect to an encrypted wireless network, so you'll have to use an initrd with custom premount scripts, possibly changing initrd and kernel compression to LZMA and hope that everything fits on the SPI flash. And your main immediate problem will be that even if you put kernel and initrd to the SPI flash, you can't read it back from the u-boot yet (unless you utilize SPL FIT support which will require some changes to the boot sequence too).

It is possible but require support from hardware manufacturers like pxe does. At this moment what you can do is, load kernel along with initramfs from local medium, and mount root partition via NFS or something similar.
