This commit adds support for the OCEDO Koala
SOC: Qualcomm QCA9558 (Scorpion)
RAM: 128MB
FLASH: 16MiB
WLAN1: QCA9558 2.4 GHz 802.11bgn 3x3
WLAN2: QCA9880 5 GHz 802.11nac 3x3
INPUT: RESET button
LED: Power, LAN, WiFi 2.4, WiFi 5, SYS
Serial: Header Next to Black metal shield
Pinout is 3.3V - GND - TX - RX (Arrow Pad is 3.3V)
The Serial setting is 115200-8-N-1.
Tested and working:
- Ethernet
- 2.4 GHz WiFi
- 5 GHz WiFi
- TFTP boot from ramdisk image
- Installation via ramdisk image
- OpenWRT sysupgrade
- Buttons
- LEDs
Installation seems to be possible only through booting an OpenWRT
ramdisk image.
Hold down the reset button while powering on the device. It will load a
ramdisk image named 'koala-uImage-initramfs-lzma.bin' from 192.168.100.8.
Note: depending on the present software, the device might also try to
pull a file called 'koala-uimage-factory'. Only the name differs, it
is still used as a ramdisk image.
Wait for the ramdisk image to boot. OpenWRT can be written to the flash
via sysupgrade or mtd.
Due to the flip-flop bootloader which we not (yet) support, you need to
set the partition the bootloader is selecting. It is possible from the
initramfs image with
> fw_setenv bootcmd run bootcmd_1
Afterwards you can reboot the device.
