OTA Problems

Postby Bartosz » Tue Jul 09, 2019 8:40 pm

mesh config:
routerless, one device configured as MESH_ROOT another as MESH_NODE, root communicate with PC via UART

problem conditions:
OTA data is transfered to ROOT, then mlink_ota_send_task is started to program another NODE

1) NODE random crashes during OAT transfer from ROOT to NODE (approximately 1 of 3 OTA transfer fails), after NODE reebots it enter upgrade mode again and crash again in infinite loop, it stops after ROOT mupgrade_firmware_stop():
I (17371) mesh: 1888<arm>parent monitor, my layer:2(cap:16), interval:12560ms, retries:2<>

Rebooting...

2) after NODE enters upgrade mode always watchdog warnings appears (OTA ends with success):

This problem is caused by insufficient memory.

```
E (23801) [mwifi, 815]: <ESP_ERR_NO_MEM> Realloc size: 1456, new_ptr: 0x0, heap free: 10816
```

1. Check if your configuration is as follows:
Image

2. If you can't provide a complete log of your child nodes, check the memory usage.

Thanks for advice, surprisingly my number of mesh buffer queues was set to 64, after change to 32 there's no more crashes.
Watchdog warnings still happens.

Please provide the code of `node_handle_task`

It's looks like during OTA root transfers data with maximum bandwidth - node generates watchdog warning and there is also no communication with node during OTA. Adding delay in mupgrade_firmware_send() loop resolves all problems.

mupgrade_root.c function mupgrade_firmware_send:
....
/**
* @brief Send firmware data to unfinished devide.
*/
if ((MWIFI_ADDR_IS_ANY(addrs_list) || MWIFI_ADDR_IS_BROADCAST(addrs_list))
&& result->successed_num < 2 && addrs_num == 1) {
MDF_LOGD("seq: %d, size: %d, addrs_num: %d", packet->seq, packet->size, addrs_num);

if (MWIFI_ADDR_IS_ANY(addrs_list) && result->successed_num == 1) {
uint8_t broadcast_addr[] = MWIFI_ADDR_BROADCAST;
ret = mwifi_root_write(broadcast_addr, addrs_num, &type,
packet, sizeof(mupgrade_packet_t), true);
} else {
ret = mwifi_root_write(addrs_list, addrs_num, &type,
packet, sizeof(mupgrade_packet_t), true);
}
} else {
MDF_LOGD("seq: %d, size: %d, addrs_num: %d", packet->seq, packet->size, result->requested_num);
ret = mwifi_root_write(result->requested_addr, result->requested_num, &type,
packet, sizeof(mupgrade_packet_t), true);
}

//slow down
vTaskDelay(100 / portTICK_PERIOD_MS); //!!!!!!!!!!!!!!!

MDF_ERROR_CONTINUE(ret != ESP_OK, "<%s> Mwifi root write", mdf_err_to_name(ret));
...

1. I hope to provide a complete log of the problem.https://docs.espressif.com/projects/esp ... l#feedback
2. Set the mupgrade log level to reduce log output

Code: Select all

     
     Esp_log_level_set("*", ESP_LOG_INFO);
     Esp_log_level_set("mupgrade_node", ESP_LOG_INFO);
     Esp_log_level_set("mupgrade_root", ESP_LOG_INFO);

I've upgrade MDF to v1.0-beta1-2-gc1cc50f and recreate my project - now everything is ok.
I was basing on examples\development_kit\light but I've mess with sdkconfig.defaults, now I notice that there are many overrides of standard settings - I suppose that it was source of all my problems.
