yeah, what the PXA270 first fetch is on prom, and prom is ReeadOnly
... so i mean if you erase/damage the "flash" (which should be "Write
Protected" by CPLD) contents
what happens, so ? supposing you have erased (stuffing 0x00) the whole
flash, could you repair your akita in order to reprogram the flash and
make it still booting into something useful ?
(i was supposing you can repair with a jtag)

only jtag should have sense: (speculative ideas) sharp could have put
the prom on akita with a soldered empty flash, than assembled the
whole, and finally plugged a jtag on the back to program the flash
isn't reasonable ?
(this schema is exactly what has been done on my ppc board: flash has
been programmed by jtage after it was soldered on board)
