HCL:GeekForce

The AsiaRF Geek Force is a Single-Board Computer (SBC).

Technical data

• Mediatek MT7623 SoC
  • 4x ARM Cortex-A7 CPU @ 1.3 GHz
• 1 GB RAM
• Raspberry Pi compatible 26-pin header

The UART1 pins are GND(?), TX, RX, GND from power button towards switch 1. If connecting the pin closest to the power button to GND, U-Boot serial input on UART2 no longer works for some reason.

Manual installation

Mainline kernel

You can use mt7623-evb.dtb until a proper mk7623-geekforce.dts is ready.

cat arch/arm/boot/zImage arch/arm/boot/dts/mt7623-evb.dtb > zImage+dtb
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n Kernel -d zImage+dtb iverson_uImage

You will need to go to a U-Boot prompt and override the bootargs variable due to differing console= device names:

setenv bootargs 'console=ttyS0,115200n8'
tftpboot
bootm

As of next-20170106 still only serial is working, no MMC or network.
