Is setup on these more like ST's Cortex-M (wire debugger to SWD lines; connect the debugger to PC, flash a bare-metal program that interacts with peripherals using MMIO and prints to CLI using RTT), like a PC or Raspberry Pi (Plug in GPOS installation USB stick, but maybe it's on a custom PCB), or neither/a mix?
It sounds like maybe the flash/RAM is offboard? Q/OctoSPI or something else?
