* Get the [ESP-IDF v4.0](https://github.com/espressif/esp-idf/releases/tag/v4.0)
|
|
* Follow Steps 1 through 3 of the [Documentation](https://docs.espressif.com/projects/esp-idf/en/v4.0/get-started/index.html#step-1-install-prerequisites)
|
|
* Comment out line 303 of `esp-idf/components/driver/sdspi_host.c` to enable the shared SPI bus
|
|
|
|
```c
|
|
// Initialize SPI bus
|
|
esp_err_t ret = spi_bus_initialize((spi_host_device_t)slot, &buscfg,
|
|
slot_config->dma_channel);
|
|
if (ret != ESP_OK) {
|
|
ESP_LOGD(TAG, "spi_bus_initialize failed with rc=0x%x", ret);
|
|
//return ret;
|
|
}
|
|
```
|
|
|
|
* Modify the `export.sh` script in the `game` directory and fill out `IDF_PATH` and `IDF_TOOLS_PATH`
|
|
* `IDF_PATH` is the extracted ESP-IDF
|
|
* `IDF_TOOLS_PATH` is the path to the toolchain
|
|
* `source export.sh`
