   Yes, I suppose this would be a functional way to do this. It would take much longer (double or quadruple depending on data bus size). But none the less, it could work.

   This would work. And I have done this. You need a jtag port and the flash needs to be directly connected to the SOC/MCU/FPGA. This is similar to how EJTAG works but without ejtag, you need to specify the pins themselves. As long a

   Updated. Curious about how you wound up tying all 30+ pins on the pico (26 gpio)

   This also does work. Some devices do not have the ability to connect to a part though (no bsdl, no jtag header)

   Oh yes it is convoluted. This is for parallel nor flash though, not serial. I suppose a pi could work I am just confused how you would dump it over serial. You need to connect: D0-D15 A0-A15 CE (STATIC) OE (STATIC) WE (STATIC) WP (STATIC)

   The binwalk is more than likely not aligned for the endianess that is used. This dump was made to just be an example that magic existed and there was data that came from the flash chip using this method. Not necessarily the binary enumerati
