I can get the messages to stop with the following, does it look good to you? case EC_CMD_ENTERING_MODE: len = 0; break; + case EC_CMD_GET_NEXT_EVENT: { + struct ec_response_get_next_event *resp = resp_data; + resp->event_type = EC_MKBP_EVENT_KEY_MATRIX; + cros_ec_keyscan(ec, resp->data.key_matrix); + len = sizeof(*resp); + break; + } default: printf(" ** Unknown EC command %#02x\n", req_hdr->command); return -1; That's more or less only what the cros-ec-keyb counterpart expects. But it doesn't test the -EC_RES_UNAVAILABLE thing or the fallback to the old method.
