Summary of what changed:
- kboot stage0 is unchanged
- kboot stage1 is unchanged
- main config has changed
- backup config is unchanged, but only because it got backed-up from main config during the upgrade.
- v22.08.2 firmware is still in slot1
- v23.09.0 firmware is now in slot2
- SPIFFS has changed but I never took a look originally. It's expected with any new settings.
Hex dumping the main config which changed, and the backup config which has the original.

Main config starts at 0x4000. Backup config starts at 0x5000
Docs are https://github.com/loboris/Kboot/blob/master/Kboot.md
Each config entry is 32 bytes, an entire line above, and kboot supports 8 entries.
The first 4 bytes always start like "0x5aa5d0c*" and the last nible is a 4 bit mask called "Entry flags", they are
- 0001 = This is the ACTIVE flag, if set, this is the active configuration to use.
- 0010 = this is the CRC32 flag, if set, the app's calculated CRC32 value must match the configuration's CRC32 value.
- 0100 = This is the AES256 flag, if set, the app's calculated AES256 value must match after the application sha256 hash.
- 1000 = this is the SIZE flag, if set, the app's size must match the configuration's size value.
We can see that main configuration has Entry flags of "D"=1101 (Check SIZE, Check AES256, Ignore CRC32, Is ACTIVE) We can see its backup configuration had Entry flags of "5"=0101 (Ignore SIZE, Check AES256, Ignore CRC32, Is ACTIVE)
The next 4 bytes, as a big-endian int, are the location of the application in SPI Flash. We can see that it was at 0x80000 in the backup config and that it is now at 0x280000 in main config.
The next 4 bytes, as a big-endian int, are the application size. We can see that the backup config indicates the application size was 1744896 when up above we see that it was really 1716288, but because the configuration entry flag was "5"=0101, the highest SIZE flag was not set and there were no problems. In the new configuration which uses "D"=1101, the highest SIZE flag is set and we have a matching size in configuration of 1902592 in slot 2.
The next 4 bytes are the application's CRC32 value, in both cases above they are 0x24 0xc6 0xab 0xaa bytes, but according to the configuration, they're not used and I don't know what they mean, just that they came from config.bin within the kboot.kfpkg archive.
The next 16 bytes are the application name or description, in our case, it's "firmware" follwed by 8 null bytes.
