Hello All,
I have downloaded new u-boot (u-boot -2009.06) I am using PQ3 - 8548
processor.
Our custom board is with 128Mbyte Flash, but MPC8548CDS and SBC8548 are
with different configurations.
How can i customize this to my custom board, which has 128Mbyte flash
interface.
I changed the Flash Base location to 0xf8000000 and Banks, Sector
informations. But still not booting. The clock configuration is fine
(33.33MHz)
When i debugged using JTAG, i could notice, when Program Counter is at
0xfff80e00 - its stoping further execution?
how can i proceed?
regards
raghavendra

What is at 0xfff80e00?
This sounds suspiciously like your processor is taking exception (trap)
0xe00. What is trap 0xe00 on the 8548? Why might it get triggered?
