Re: Redboot - Cirrus EP9315 and Spansion S29GL512N problem


hi !

i have worked for a company where ep93xx and spansion flashes are used, please 
look at http://dev.contec.at, there i have made a redboot bootloader which 
can handle such flashes, but i have used flash_v2 branche, so it will not 
help u.

this things i have only seen if the mmu is set up wrong, so maybe it helps 
check your mmu settings in redboot. maybe the 512 chip adresses obverlap 
somewhere...
