Hello,

I am trying to read the data0/data1 fields from the flash option byte register.

When the flash read protection level is 0 - I can do that no problem, but when the read protection is set to 1 it fails.

According to the reference manual there should be no problem to read the option bytes under protection level 1.

Any help is highly appreciated

Thanks,

ron

Read it from where, and with what?

Code in the F3 should be able read and display the state of the option bytes whatever the protection level externally.
