Could we have some guiding how to get shell by UART on SOEdge?
I experiment with that currently, no success. Same issues as for another guys at this forum.
Tried both Factory_Test_Build and BSP_Linux_ver_1.1_Build_from_SDK images from here: https://wiki.pine64.org/wiki/SOEdge
Wrote uncompressed image to SD card using just `dd`, but see nothing in UART and ethernet while booting it.
Rockchip Wiki tells that "The U-boot will make partition when first time boot up": http://rockchip.wikidot.com/linux-develop-guide#toc6
- but I don't see partitions on SD card even after boot.
Another option suggested there and here: https://forum.pine64.org/showthread.php?...#pid100414
is flashing by USB using rkflashloader, but I see only USB host described in SOEdge specs (not USB device or USB OTG). So I'm afraid to damage it or my PC if I connect two USB hosts by USB A <--> USB A cable.
As for UART, I failed to find pinout chart for SOEdge so used this info from Raspberry assuming they are same (SOEdge pins are labeled as "PI-2 GPIO"): https://www.raspberrypi.com/documentatio...pin-header
I have this USB UART adapter: https://pine64.com/product/serial-consol...er-edition
Set yellow jumper on 3.3V and connected to pins # 6,8,10 but still nothing in minicom/screen at my Linux host. Tried to swap TX/RX wires, no result.

Images seem to have custom format by Rockchip, can be unpacked by rkflashtool:
https://github.com/linux-rockchip/rkflashtool.git
https://github.com/ayufan-rock64/rkflashtool.git
There are UART-related parameters in "second" file inside boot.img (inside embedded-update.img, inside update-soedge-factory-test-2021-03-23.img)
and I see /etc/init.d/S50sshd inside rootfs.img - but still not sure if UART console and sshd are really activated at boot.
Any comments will be greatly appreciated!
