Mainline support is WIP.
Manual build
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
U-Boot
Mainline U-Boot
Still being done. To try out the working-in-progress code, retrieve the code at [1] and use the sipeed_maixsense_defconfig build target.
Linux Kernel
Mainline kernel
Still being done. To try out the working-in-progress code, retrieve the code at [2] and use the sun50i-r329-maixsense.dtb device-tree binary.
Tips, Tricks, Caveats
FEL mode
By default no SPI Flash is soldered, that means just removing SD card makes the SoC to enter FEL.
Adding a serial port
Just plug a cable connected to your PC to the port at the down side (next to the 4-pin connector, which provides another UART, not the debug one). An onboard CH340 USB-UART bridge is available for accessing the debug UART.
