this looks like a useful adaptor for debugging a compact flash interface |

how will you program the initial boot loader - jtag? or will you have a tiny in-system-programmable qfp flash memory and a programmer?
when debugging the cpu board, it can help to put the cpu into an adaptor so you can probe the pins more easily, essential if the CPU is BGA. might want/need a logic analyser to check the memory interface timings, although these days the "heisenberg uncertainty effect" means that simply probing the bus can introduce more clock skew and make a broken system worse! |
