The PQ1 comes out of reset with CS0 owning all of the 4Gig address space hence the flash is always normally at zero to start with. Then normally this is then reduced and relocated up to 0xfe000000 and the SDRAM then located back down to zero. Hence the boot loader starts in flash offset of 0x00000000 then runs with offset 0xfe000000 in flash then usually it copies its self into SDRAM (.. after setting this up of course.) from address offset 0x00000000. Please note: The MBX template is VERY OUT OF date Regards Frank Robbins Email: frank.robbins@analogue-micro.com web:http://www.analogue-micro.com Analogue & Micro Ltd 9 Clytha Park Road Newport NP20 4PB UK (Great Britain) Tel : 44 (0)1633 666787 Fax : 44 (0)1633 666788 Michael Dorin wrote: >Hello, > >I have an 860T based board and am trying to convert >the MBX templete.
