You can only erase a whole sector, you can't change a single byte without doing that. Technically you can change 1's to 0's but in this case the value is already 0 and the new hash/checksum will almost certainly require setting 0's to 1's.

Let's try to keep the thread clean of guessing.

OFDM modem is just part of wifi.

To do this you would have to erase the existing partition table and if you fail to write a valid replacement for some reason like power loss the device will be bricked. And you also have to enable SPI_FLASH_DANGEROUS_WRITE

123 can_rx 1 no can_tx 1’d1
124 - - - can_bus_off_on 1’d1
125 - - - can_clkout 1’d1

Datasheet hints that it still has CAN

It is closed source. But you can look at the stub loader code in esptool. Why can't you fix the hardware issue?

You should sell bare board without firmware to use as esp32 universal IR/RF dev kit.

It is related to bugfixes that are required for certain silicon versions. If you know you will only ship v1 chips you can eliminate the workarounds for v0. If you know you will only ship v2 chips (future) you can eliminate v0 & v1 workarounds. However it isn't fully implemented yet afaict.

Is bond 2 with esp32 shipping now or still mt7688 version?
