Manual build
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

Sunxi/Legacy U-Boot
Use the  build target.

Mainline U-Boot
Use the Nintendo_NES_Classic_Edition_defconfig build target.

Sunxi/Legacy Kernel
Use the nintendo_nes_classic_edition.fex file.

Mainline kernel
Use the 'sun8i-r16-nintendo-nes-classic.dtb' device-tree binary.

Use the 'sun8i-r16-nintendo-super-nes-classic.dtb' device-tree binary.

= Tips, Tricks, Caveats =

FEL mode
The RESET button triggers FEL mode. Alternatively, send the character '2' to UART (DRAM is NOT initialized), or run 'fastboot' command on stock U-Boot (DRAM is initialized).

To verify you have successfully entered FEL mode, check the output of. For the Nintendo NES Classic Edition, it should look like: AWUSBFEX soc=00001667(A33) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000

Stock U-Boot
To enable boot0 debug mode (it gives command prompt on U-Boot), send the character 's' to UART.

HDMI
EPMI EP952 bridge chip is used.

Gamepad
compatible with Wii Classic Controller. (i.e. I2C)

PG3/PG2 are used to detect controllers. (HIGH: connected)

PF0-PF5 (SDC0)


There are PF0-PF5 and DCDC1 on SIDE-B. They can be used for SDC0.

= Adding a serial port (voids warranty) =

Locating the UART


There are PB0/PB1 (for mainline) and PF2/PF4 (for stock firmware) on SIDE-A.

If you want to use the PF2/PF4 pins using the mainline U-Boot, you'll need to change CONS_INDEX to 1, and set UART0_PORT_F in menuconfig.
