RE: [ECOS] Redboot on IXDPG425 using P30 Flash

["Abraham Celik" <abrahamc at emtec dot com dot au>]

Hi Mark,

Thanks for that.

Do you know where/how the unlock code for the flash in redboot is? I search
around everywhere and could find anywhere? I can see that the P30 has some
weird locking systems (we used the P30 cause Intel are pushing to phase out
the J series). I can ensure you there is not external locking mechanisms.

Also how do I hardcode the MAC before I compile the binary image? I tried to
hardcode the IP settings but this didn't seem to work (as I image it wont
until I program the MAC).

Regards, 

Abraham Celik

I'm pretty sure the a2 error code is a write protect error. So either the
unlock code is not working or there is some external write-protect circuitry
getting in the way.

The mac address (depending on configuration) can be hard-coded in RedBoot,
stored in an EEPROM, or stored in FLASH. If you don't have the command to
set the MAC, most likely it is being stored in FLASH and you'll have to sort
out that problem first.
