Resolved! Can I use DMA to copy data in parallel with the MCU operation to/from (1) On-chip Flash, (2)Off-chip Flash (connected via Quad-SPI), or (3) Off-chip SDRAM (connected via FMC)? If possible, which one will be the fastest?

From the datasheet diagram (attached), it seems like the DMA has access to all of above. However, it is not clear whether it is really possible to DMA data to / from those and how I should do it and I've seen negative response to similar chips, so I ...

MCO pin showing 24 MHz instead of 48 MHz while debugging

I use the MCO pin to test my clock configuration on a STM32F072RBT6 board. While I'm debugging with a ST-Link/V2 adapter the MCO output shows 24 MHz instead of the expected 48 MHz.Using the exact same software (no changes in clock configuration) and ...
