Hi
don't know in detail.
talking about reflashing. I am not understand the detail about those commands:
cable milkymist
detect
(I maybe can guess those two commands do)
instruction CFG_OUT 000100 BYPASS
instruction CFG_IN 000101 BYPASS
(what are those two doing??
pld load fjmem.bit
(send fjmem.bit to fpga?, what fjmem doing after load?)
initbus fjmem opcode=000010
frequency 6000000
(don't understand)
detectflash 0
endian big
flashmem 0xD20000 mm1.yaffs.flash5.bin noverify
(how flashmem working in detail?)
thanks
