Hi Edvin,

Thanks! This works. What about storing a hex value, and not a string?

Additionally, on my second point above, do you have any idea why I am only able to see some log messages on running the example?

Hello,

It is correct as you say, you can only write from 1 to 0, and need to erase in between.

Try to write "write -h". It says that you write ASCII bytes to the flash. In hex values, the ASCII string DEADBEEF is 0x44:45:41:44:42:45:45:46. You can find the ASCII table e.g. here.

If you write the commands:

erase 0x3E000 1
write 0x3E000 DEADBEEF
read str 0x3E000 8

It will print DEADBEEF, because it reads the string, and prints ascii symbols.
