Hi,

I have also tried with custom csv partitions as well but issue remains same.

# Name, Type, SubType, Offset, Size
nvs, data, nvs, 0x9000, 0x4000
otadata, data, ota, 0xd000, 0x2000
phy_init, data, phy, 0xf000, 0x1000
factory, app, factory, 0x10000, 1M
ota_0, app, ota_0, 0x110000, 2M
ota_1, app, ota_1, 0x310000, 2M

Please let me know if anyone has any idea for this issue.

Hi All,

We are using ESP32-idf RTOS SDK of 20th December GIT Release with following last commits.

commit cca883490e3d7142457309d54ab3d692cf5c2d0d
Merge: ba08d1a d60ff9b
Author: Wu Jian Gang <wujiangang@espressif.com>
Date: Tue Dec 20 11:18:17 2016 +0800

Merge branch 'bugfix/tcpip_adapter_set_ip_info' into 'master'

Fix set static IP address issue

Set static IP address, clear current DNS servers default.

See merge request !310

So, Please let me know if this issue has been fixed into latest SDK or anyone has any idea or clue to solve this type of issue.

If the OTA partition has leftover data in it from a previous flash, it will error out in this way. Try "esptool.py --port PORT erase_flash" to erase the flash.

(On more recent esp-idf versions, ie current master, you can run "make erase_flash" for the same result.)

Thanks for reply.

It means OTA data partition has been corrupted due to some way and it can be resolved using flash erase command. But I want to know that what part of ESP32 section will write that OTA data partition?

Please let me know if you have any idea...

Running an OTA update will write to this section, as it contains metadata about which OTA partition is currently selected.

However, if you previously ran different (non-OTA) code on this module, with a different partition table, then there can be invalid data there from before OTA was even enabled.

OK. Got it. Let me check by erasing SPI flash memory and will let you know if it is working or not.

Because, I have flashed OTA as well as non OTA code multiple times on this module which causes this issue.

Thanks for support.

Hi,

I have checked with flash_erase and it works for me but it seems like if i change partition table then it is going to create problem which means that I have to finalize partition table onetime to recover this issue.

Let me know if i am wrong.

You don't necessarily have to finalize the partition table, but if you move the ota_data partition then you'll need to erase the flash in that partition. (You can do this by erasing the entire flash, or using esptool.py erase_region to erase the ota_data partition's sectors only.)

Hi,

Thanks for Reply.

I have one quick question that can I allocate more than 1 MB for OTA Factory and OTA_0 partitions as i have tried with following OTA Partition CSV file but not worked.

# Name, Type, SubType, Offset, Size
nvs, data, nvs, 0x9000, 0x4000
otadata, data, ota, 0xd000, 0x2000
phy_init, data, phy, 0xf000, 0x1000
factory, app, factory, 0x10000, 0x200000
ota_0, app, ota_0, 0x210000,0x200000

Above partition table is only working if allocated factory and ota_0 partitions as 1MB. Even if I have also tried with 1.5 MB but issue remains same.

Please let me know if there is any limitations for that.
