I want to develop trusted apps for the board, and in order to do so apparently I need to build optee repos. The configuration for those repos is chipset/board specifc and so far I'm a bit in the dark.
It looks like the correct platform setting would be plat-sunxi with PLATFORM_FLAVOR_sunxi501-a64. Is this correct? Is there a rockpro64 configuration somewhere already set up?
Every now and then when I boot from a SD card I get the error `Ethernet not found.` during the boot sequence and then I am in some shell.
After a power off/on booting eventually works.
I experienced that with more than one Linux, so I think it is not release specific.
Last week I upgraded from Ubuntu 16.01 to Ubuntu 18.01 and am now running 4.4.132-1075-rockchip-ayufan-ga83beded8524.
While my core functions are working (SFTP and Samba) I keep getting "Errors were encountered while processing: initramfs-tools" when trying to update. I'm not particularly experienced in reading logs so below is the most recent apt-get upgrade log in the hopes some one can point me to a solution for this error. I suspect that failure to fix this will prevent future image upgrades.
Any help is greatly appreciated.
Many thanks.
Tom

line that appears next after cold boot.
mrfixit2001 kernel reboots fine as well as ayufan mainline (though the latter misses eMMC which is a showstopper).
Attaching a long log file containing normal boot and a hang after restart.
Strangely... another board (same RockPRO64 v2.1 4g) manufactured 1 month earlier doesn't have the issue. I tried swapping eMMC to make sure it's not a tainted distributive and the problem remained on the same board each time.
Is there any way I can use the Espressif's ESP32 Module as only WiFi and Bluetooth Module for Rock64 using the GPIO Pins/Interface (e.g. UART/SPI/I2C)?
I can't find any references which would allow this functionality. All I could find are code examples for using ESP32 as standalone microcontroller
My goal is to use ESP32 as WiFi and Bluetooth Module on Android
