I am using bootloader to update my firmware and I am using dual bank to update code. When I working on bank 1, new code sending to bank2 after reset I am starting bank2 successfly, but I want to use Read Out Projection in my MCU.

If I use Read Out Protection I have some question about that:

1) If the read out protection enable, can I use dual bank?

2) If the read out protection enable, can I update firmware with IAP-Tftp ?

You cannot disable RDP without a full chip erase + reset, so that will be an issue.

It's possible you can use the Proprietary code readout protection (PCROP) instead if you chip supports it.

For once, can be full chip erase, this is not problem for me.

I want to protect my own code to read, after the programming.I want to be able to update the code via tftp even if the reading protection is active.

does reading protection prevent dual bank flash management ?
