Warnings while flashing OTA, no errors reported, OTA fails

Posted: Thu Mar 07, 2019 8:21 pm

I am trying to flash an OTA partition on a slave device in the network. The master chops and sends it a firmware, the slave rebuilds it and checks the CRC, then the slave tries to flash it, but fails to do so. The code that updates the OTA is identical to the code used on the master, where it has always worked. The code essentially follows the OTA example, only error-handling is different.

Below is the output from a test program, with some comments inserted. The code is simplified to a minimum: on boot it flashes the firmware. The code causes these info/warnings (see comments in between), but nevertheless completes without error.

I suspected leftover invalid otadata might cause problems, so I have tried to erase the flash using esptool. I have adjusted the partition table to the same effect. I have flashed the firmware using esptool directly, and then all is fine. Summary: I have no clue what is going on. I do not understand what the error-messages (warning really) relate to.

Any help much appreciated!

Code: Select all


// this is the result on a reboot (after boot the code will flash the OTA, again):

In other words, what (problem) do the messages below indicate? They occur during both esp_ota_end() and esp_ota_set_boot_partition(), from standard (example) code that works (and is silent) on one device (the network master) and not on another (a network slave).
The problem continues after a `make erase_flash`.

Houston we have a solution :D

Take a look at the partition table as reported above:
Code: [Select all] [Expand/Collapse]
  1. I (103) boot:  6 storage          Unknown data     01 82 002b0000 00100000
  2. I (110) boot:  7 fonts            OTA data         01 00 003b0000 00050000
  3. I (118) boot: End of partition table
GeSHi © Codebox Plus Extension
Note that partition 7, which otherwise was fully functional, is of the wrong type and subtype: "OTA data 01".

I replaced the entry in the partition table with "fonts, 0x40, 0, , 0x050000," and now the OTA update works.

The info messages produced continue, but apparently they had nothing to do with the problem. Maybe they occur when the device is in 40MHz SPI mode, whereas the other device runs it at 80Mhz.

Thanks.
