ESP32C3: TWAI_ALERT_RX_FIFO_OVERRUN
Posted: Thu Apr 20, 2023 2:02 pm
Using an ESP32C3 for ECU reprogramming. Everything works fine in testing mode where I have a bunch of milliseconds delay between frames. When I let the ECUs go "full throttle", the ESP32C3 TWAI chokes with "TWAI_ALERT_RX_FIFO_OVERRUN". Since this is NOT queue-based (my rx queue length is 600 and thus should accomodate a full ISOTP PDU), I wonder what the problem is and what are my options?
