I have not tried it, so I do not know yet if QMI is accessible from SWD when the MCU is in bootloader mode.Do you have access to QMI registers ?
You could use QSPI direct-mode interface.
I did use QSPI direct mode (memory mapping) with STM32H7 and external flash, and while it is working well, the amount of code is much much more than when using BOOTROM in RP2040/RP2350. I think I will also need to access the OSC registers to switch to faster clock.
I think QSPI in RP2350 will be a fun project to do in the near future. But for now, I still wonder what is missing from the datasheet to work properly with RP-AP and other "weird" things in RP2350.
