I cannot find some details about how this dual bank mode works. Can anybody make my questions clear?
If DB1M is enabled, does sectors numbering change also for WRP and/or PCROP protection setting? If DB1M is enabled, can 1MByte device boot from bank 2 (bit BFB2)? What will happen if DB1M will be enabled on device with different density (2MByte)? Thanks a lot for your help. Jozef #stm32f4 #flash-dual-bank2014-09-01 05:39 AM
I've only ever seen One Bank 1MB devices, and Two Bank 2MB devices.
You might have to do some of your own experimentation, and review the System Loader ROM I would imagine that it would behave similarly to the Two Bank 2MB devices, that the sector numbering would be discontinuous, and the memory perhaps also.
