Industrial A133 development board. Breaks out peripherals including serial, I2C, SPI on JST connectors, but also offers standard USB 2.0 and 100M Ethernet connectors. Different versions of the board ship with different video interfaces: LVDS on 2mm pin headers, MIPI-DSI FPC, or 40/50pin RGB FPC connectors. Ships with Android.

Mainline U-Boot

Not yet merged, but generic A133 and DRAM patches are on the list. defconfig file pending.

Mainline Linux Kernel

Not yet merged, but patches are on the list.

Tips, Tricks, Caveats

FEL mode

The FEL button triggers FEL mode.

BSP boot log

The Android version installed on the eMMC boots a BSP based Linux kernel. The firmware (boot0, TF-A, U-Boot) messages are shown on UART0, but the kernel does not output anything.

Accessing the serial port

UART0 is exposed on a 4-pin JST 2.0mm header (GND-RX-TX-VCC, as indicated on the silkscreen). It's the usual 3.3V TTL level, refer to the UART howto for more details.
