That's even better and was the solution that I was looking for.
The question is how, from the OS, can I update the FIS. Obviously
I need to know the structure of the "FIS directory" partition and
find the offset of that checksum and insert a '0' there by
- reading the whole partition into ram,
- changing the bit, erasing the partition on the flash,
- and finally flashing the modified partition in the ram back.
Any suggestions as to where to start?
Thanks!
