Hi there!
I would like to modify my the boot device on the TS-228A to exchange my old NAS326.
My first goal would be to boot Linux on a flash drive. IIRC this SoC pretty much gained mainline support for the Linux kernel in the recent years, compared to how RTD12xx was in the first years.
Specs:
* Realtek RTD1295 4-core 1.4GHz processor (ARMv8 - 64bit)
* 1GB DDR4
* 4GB eMMC
* Gbit ethernet
* 1xUSB3.0, 2xUSB2.0
* 2x 3,5" HDD bays
I've found the UART port, which is easily accessible from the top if you remove the HDD plastic cover.
--1---2---3----4----
|TX|NC|RX|GND|
-----------------------
classic 115200, 8N1, 3.3Volts.
But I couldn't get the U-Boot shell, even if there is a message in the logs:
"Hit Esc or Tab key to enter console mode or rescue linux: 0"
I tried the factory methods to mess up the image restore, but nothing really works.
I can see the active voltage on the RX pin, but it's picking up the keyboard signals trough the minicom terminal.
Do you have any ideas how to interact with U-Boot?
