* Fix Tinker Board S (eMMC) boot (#650) Use Tinker Board S U-Boot configuration which is capable to boot from eMMC as well as from SD card. Note that this makes U-Boot always claiming to run on Tinker Board S: .. Model: Rockchip RK3288 Asus Tinker Board S .. It seems that there is no generic Tinker Board configuration. However, Tinker Board S configuration really seems to work well with Tinker Board as well, so just use it. Also today the U-Boot Makefile seems to generate a working idbloader.img already. Drop our special handling. * Use Tinker Board S device tree if booting from eMMC for Linux Instead of patching the Tinker Board device tree, select the device tree based on what device we are booting from. Note: This boots the non-S device tree when booting a Tinker Board S from SD card! But there is no reliable detection otherwise, so let's just live with that fact. * Document how to use our U-Boot to flash eMMC

## eMMC
|
|
|
|
eMMC support is provided with the same image. Just flash the image to the eMMC by connecting your Tinker Board S to your PC via Micro-USB. Refer to the Tinkerboard documentation how-to flash using Micro-USB and UMS.
|
|
|
|
The Home Assistant OS provided U-Boot does support UMS as well,
|
|
however manual intervention is necessary:
|
|
|
|
1. Set the jumper between Micro-USB and HDMI the maskrom mode
|
|
2. Insert SD card and connect the board via Micro-USB to your PC
|
|
3. Continusly press Ctrl+C to interrupt boot
|
|
4. Set the jumper back to the park position
|
|
5. Start UMS using:
|
|
```
|
|
ums 0 mmc 0
|
|
```
|
|
6. A mass storage device should appear. Flash Home Assistant OS to it.
|
|
|
|
## Serial console
|
|
|
|
To access the terminal over serial console, add `console=ttyS2,115200` to `cmdline.txt`. GPIO pins are: 34 = GND / 32 = UART TXD / 33 = UART RXD.
