The software is copied to DRAM, same memory situation in both cases.
In principle it is possible to run directly from flash (and save memory), my
bootloader is prepared to do so, but we haven't tried yet. Flash access is
slower than DRAM.

Yes, me for example. Irony had it that my box wasn't flashable. I exchanged
the chip and programmed it with the UART boot mod. You should be able to find
postings about it. A few other people followed that, I send them my spare
chips. But now I'm out of those.
The surgery is not so easy, you need SMT soldering equipment and skills:
