General • Small clarifications on programming the internal flash on 2354.

The manual says:

The internal flash die can also be programmed externally by holding the RP2350 die in reset via the RUN pin (active-low
reset), and driving QSPI signals into the chip from an external programmer

I assume you can drive single-pin SPI to program the flash, just more slowly, right ?

And does the UART boot loader allow you to program the flash via serial ? Or is it just SPI that has write access ?
