From: Mark Cave-Ayland <[email protected]> The call to esp_dma_enable() was being made with the SYSBUS_ESP type instead of the ESP type. This meant that when GPIO 1 was being used to trigger a DMA request from an external DMA controller, the setting of ESPState's dma_enabled field would clobber unknown memory whilst the dma_cb callback pointer would typically return NULL so the DMA request would never start.
