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) >> anybody has ever thought anything similar for akita ?

There is just a serial IOPORT and few other wires. > I am not sure what is the purpose of connector under the battery cover. 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) _______________________________________________ Zaurus-devel mailing list Zaurusfirstname.lastname@example.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/zaurus-devel
