Memory mapping in RM0432 Rev. 5 - STM32L4R5, R7, R9 wrong?!

Andreas Bolsch · ‎2019-06-22

Fig. 2 (Memory map) seems to be incorrect as it states

OctoSPI bank2: below 0x60000000

FMC bank1: 0x60000000 - 0x6FFFFFFF

Reserved: 0x70000000 - 0x7FFFFFFF

FMC bank3: 0x80000000 - 0x8FFFFFFF

OctoSPI bank1: 0x90000000 - 0x9FFFFFFF

But OctoSPI bank2 is certainly at 0x70000000 - 0x7FFFFFFF (verified on hardware). Probably the 'Reserved' and 'OctoSPI bank2' are swapped.

The same error appears in the corresponding datasheet for STM32L4R5xx, STM32L4R7xx, STM32L4R9xx.

Hello @Andreas Bolsch ,

You are right, we will fix this in the coming release of RM0432 and STM32L4Rxx/L4Sxx datasheets.

Here below the fixed figure:
