Hi, I am running armv7/7.2 on this board. This is how I got it to run: from one of the images at
https://images.olimex.com/release/a20/ you extract /usr/lib/linux-image-5.10.105-olimex/sun7i-a20-olinuxino-lime2.dtb (or the other one if your board is that way) I put it in the root of the EFI (dos) partition, which is 'p1' on my image. and you extract /usr/lib/u-boot-olinuxino/a20-olinuxino/u-boot-sunxi-with-spl.bin it must go onto the image you created for bsd, in the usual place. This fixes the ethernet problem. The daily build Debian u-boot for this board did not do the trick. ------------- But I have one problem that defies me: I want to run from the sata disk. So I made an identical copy of the installation on the sata disk. However, the system needs the mmc card to boot u-boot, so I leave that in place. sd0 is the hard-disk. sd1 is the mmc device. Now the following happens: 1. u-boot is read from sd1, obviously. 2. the kernel used is sd0a:/bsd 3. but root is on sd1 ! I tried to fix it in u-boot, but bsd is obviously different from the linux kernel. And I studied the config options for the boot kernel but I do not seem to find a way to change the root, swap and dump settings. Is there any help for this? Here is the boot log as captured from the tty0 connection: ---------------- U-Boot SPL 2021.04+olimex-1-20220413.080758 (Apr 13 2022 - 08:09:11 +0000) DRAM: 1024 MiB CPU: 912000000Hz, AXI/AHB/APB: 3/2/2 Loading configuration from EEPROM: OK Verifying data: OK Trying to boot from MMC1 U-Boot 2021.04+olimex-1-20220413.080758 (Apr 13 2022 - 08:09:11 +0000) Allwinner Technology CPU: Allwinner A20 (SUN7I) ID: A20-OLinuXino-LIME2 Rev.K SN: 00011B6E MAC: 30:1F:9A:D0:8E:8A I2C: ready DRAM: 1 GiB MMC: mmc@1c0f000: 0 Loading Environment from EXT4... ** Unable to use mmc 0:auto for loading the env ** Loading Environment from FAT... ** No device specified ** HDMI connected: Setting up a 1920x1080 hdmi console (overscan 0x0) In: serial Out: vga Err: vga Allwinner mUSB OTG (Peripheral) Net: eth0: ethernet@1c50000, eth1: usb_ether starting USB...
