Hi,

 

I'm trying to install Armbian 5.20 vanilla kernel to eMMC on my Opi PC+.

After nand-sata-install finishes I shutdown the Opi PC+ and power it back on.

At least, I enable the power, I don't see anything happening in minicom on my pc.

Only when powering it with a microsd in the slot (with armbian) will the uboot show in minicom on my pc.

 

Doing a nand-sata-install with 5.14 legacy worked.

 

What am I doing wrong (especially seeing nothing after a reboot with my ttl-to-usb connected is a bit strange for this noob)?

It seems that there is a bug with improper path while trying to copy the u-boot-sunxi-with-spl.bin into the eMMC.

 

The workaround for now is booting from your sdcard and writing the u-boot manually :

dd if=/usr/lib/linux-u-boot-dev-orangepipcplus_5.20_armhf/u-boot-sunxi-with-spl.bin of=/dev/mmcblk2 bs=1024 seek=8

Then reboot without sdcard, it should work.

by the way, I wanted to know - what load faster with emmc or sdcard? there is a difference?

eMMC is faster in all cases. Check background with some tests:

@Igor

Thank you for your link.

Probably the best option eMMC

@martinayotte,

 

That worked! Thanks :-)
