Hi,

I need to remotely update a device which is currently running firmware developed using IDF 2.0 to a newer firmware developed in IDF 3.3.

I'm trying out the OTA update locally to test it out but although the new firmware does boot up after the update, it seems to be crashing nearly immediately. The print out of the crash is shown in the image below.

For reference, the bootloader of the out-dated firmware is ESP-IDF v2.0-rc1-860-g2427809c-dirty 2nd stage bootloader. I've enabled the 'App compatible with bootloaders before IDF 2.1' option in sdkconfig for the updated firmware, to no effect.

Is this process possible? I shouldn't be saving any PHY configurations to the phy_init partition, so it is my understanding that just updating the app in the firmware partition shouldn't result in any issues.

Forgive me for bumping my own thread, but does anyone have an idea on why this is happening?

Im not sure it can solve your issue, but you have such option in menuconfig:

Code: Select all

COMPATIBLE_PRE_V2_1_BOOTLOADERS

Hi,

Yes, that was already enabled.

I found the issue. It was because the firmware was attempting to mount a file-system onto a partition with subtype 'spiffs' which existed in the partition table of the new firmware, but not in the old one.

I've since managed to get around this by mounting the file-system onto an appropriate partition, but have also toyed around with trying to delete and re-flash a new partition table from the firwmare itself. This may be a bit of a derail from the original topic, but I keep getting an invalid argument error when attempting to erase the flash region containing the partition table. The amount of memory I'm trying to erase and the start memory address are 4kB aligned (see code snippet below), so I can't see why I'm getting an invalid argument. I have seen reference to the config 'SPI_FLASH_WRITING_DANGEROUS_REGIONS", but I can't enable this from the configuration menu.

Does anyone know why this is happening?

err = spi_flash_erase_range(0x8000, 0x1000);
