Building TangCore

Here's how to build the TangCore distribution, including the firmware, the monitor core and 4 game cores.

Setting up the environment

  • Windows 10 or 11
  • Install Gowin IDE 1.9.10.3 (used by all cores) and 1.9.11 (for GBATang).
  • Install git for windows.
  • Checkout tangcore and BL616 SDK/toolchain. 
    mkdir \Gowin\dev
cd \Gowin\dev
git clone --recursive https://github.com/nand2mario/tangcore.git
cd tangcore
git clone --recurse-submodules https://github.com/vossstef/bouffalo_sdk.git
git clone https://github.com/bouffalolab/toolchain_gcc_t-head_windows.git
  • Add the following dirs to path: toolchain_gcc_t-head_windows\bin, bouffalo_sdk\tools\make, bouffalo_sdk\tools\cmake\bin, bouffalo_sdk\tools\ninja

Build the firmware

First, obtain Sipeed official firmware here and save in tangcore\firmware-bl616.

cd tangcore\firmware-bl616

buildall         # build for all boards

set TANG_BOARD=mega60k
make             # build for one board

Build the cores

cd tangcore\nestang
buildall         # build for all boards

# the same for snestang, gbatang, mdtang and monitor

Collect building results

cd tangcore
build package
This will collect all built artifacts and put them in build/.
