[U-Boot] ppc-mpc8548-u-boot
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?
how can i proceed?
