Re: Re: [jornada] Schematics

Hi,

I'am looking if it would be possible to modify the original flashboard. When starting the jornada 720 it starts looking in RomBank 0 "CS0 is enabled". I would like to see if it's possible to disable rom Bank 0 and reroute the CS0 signal to an new small reprogrammable rom at address 0x0000 which contains the bootloader of somesort to refer to the first address of the Flash. you could even put in a switch to select from which you want to load.

I don't know if it's possible anyway but thats what i am figuring out.

Cheers,

Ernest.
