OTA firmware update error

[Baldhead]

Hi,

I am implementing the example "advanced_https_ota_example" https://github.com/espressif/esp-idf/bl ... _example.c with some particular changes.

After ota app update at new partition( 0x1010000 ), appear this error message, and ESP32-S3 boot from old partition ( 0x20000 ).

Code: Select all

I (83) boot: Partition Table:
I (87) boot: ## Label            Usage          Type ST Offset   Length

What can be the poblem ?

It looks as though something went wrong during the upload. Can you provide the logs from the point in time you are uploading the replacement firmware?


How are you flashing the firmware bin file? Probably the web interface provided by the example? Which file are you flashing?

As soon as i can i will send the logs, however, the message says "ota finish", which looks like the process went correctly.

I configured the apache server (i use xampp). The binary file i take in the project's build folder.

[Baldhead]

I downloaded the binary file through the chrome browser(through local apache server) and compared it with the file in the project's build folder and the files are identical.

I would like to compare with the file that esp32 write in the flash memory( firmware downloaded through ota ).

How do i download this partition (0x1010000) from the ESP32 flash memory ( using serial wire ) ?

Something like this:

Code: Select all

esptool.py -p PORT -b 115200 read_flash 0 0x400000 firmware.bin

EDIT:

I downloaded the file this way:

Code: Select all

I compared the file downloaded from ESP32-S3(by serial wire) with the file downloaded from the apache server through the chrome browser and the two files are the same.

Maybe the size of flash memory with 32MB is not supported ?!

Note:
I erased the entire flash memory with: idf.py erase-flash

[Baldhead]

Some suggestion espressif team ???

[Baldhead]

@ESP_Sprite,

Some suggestion ???

[Baldhead]

The problem, i think, is flash memory size ( 32MB ).

I changed the partition table to address below 16MB and it worked( csv file in annex ).

How to make it work for addresses above 16MB too ???

Code: Select all

I (83) boot: Partition Table:

Another doubt:

How do i configure ota to flash 4096 bytes (1 sector) at a time ?
Is it possible ?

Currently the ota is writing 1024 bytes at a time.

How do i configure ota to flash 4096 bytes (1 sector) at a time ?

Please try setting `buffer_size` field to 4096 value from `esp_http_client_config_t` structure during OTA updates initialization.

HTH!

Hi @ESP_Mahavir,

Worked, thank's.

I found it strange that the first write was with 1024 bytes.
All other writes were 4096 bytes, except of course the last write (if the image size is not divisible by 4096).

Hi @ESP_Mahavir,

Do you have any solution for the main problem ???

The problem, i think, is flash memory size ( 32MB ).

I changed the partition table to address below 16MB and it worked( csv file in annex ).

How to make it work for addresses above 16MB too ???
