OTA with esp-open-rtos

[Petar Sankovic]

Hello,

I've been trying to build ota example and run it but for some reason it's not working.

I was following OTA explanation from github wiki to the letter.

First I compiled esptool2 then rboot (with changed rboot.h) as wiki is saying.

I would like my application to be able to perform upgrade using OTA.

This is what I have done:

1. buil my app with Makefile having OTA=1 in it

2. clean flash using esptool.py -p /dev/tty.SLAB_USBtoUART erase_flash

3. load rboot.bin esptool.py -p /dev/tty.SLAB_USBtoUART --baud 115200 write_flash -fs 32m 0x0000 /esprtos/rboot/firmware/rboot.bin

4. load my bin to 0x2000 esptool.py -p /dev/tty.SLAB_USBtoUART --baud 115200 write_flash -fs 32m -fm qio -ff 40m 0x2000 mqtt_client.bin

ESP start to download new firmware from tftp but then it get stuck and get this:

TFTP client task starting...

Image will be saved in OTA slot 1.

Downloading mqtt_client.bin to slot 1...

Same thing is happening if I flash ota_basic example? What am I doing wrong? I am using esp-12e.

I'm also confused by the OTA_BASIC example. The wiki says that the example runs an tftp server and you upload from your machine using a tftp client.

But the code seems to show otherwise, like an tftp server had to run on your PC and the example would download FROM it:

        tftpclient_download_and_verify_file1(slot, &conf);

        vTaskDelay(5000 / portTICK_PERIOD_MS);

        tftpclient_download_file2(slot);

        vTaskDelay(5000 / portTICK_PERIOD_MS);

Can anyone clear this up?

TIA

Hi guys,

1) I could finally undertsand that yes, the examples was running both a client and a server. I commented the tftp server part...

2) I thought my issues with reset after update had something to do with pull-up resistors on some pins, etc - actually just pressing the Reset button once made OTA updates work now.

cheers
