Dear All,

           we have designed a MPC8280 based board which has 512MB RAM,128 MB Application flash,512KB boot flash.we have ported U-boot 1.3.1 on mpc8280, cpuis running at 300MHz. we are using only one chip select for SDRAM. SDRAM has 12 rows 10 columns.

bus clock is 100MHz

scc clock is 125MHz

vco_out is 500Mhz

CPM clock is 250 MHz

U-boot is booting and working fine. but when i give mtest command from u-boot to check SDRAM working then u-boots hangs after 1 hour giving some exception error.

i have captured the log file /error file which is got in hyper terminal during testing time. please find in the attachment.

Hello Friends,

I have a custom board with MPC8548E. I am trying to port u-boot 2009.06

By modifying the MPC8548CDS Files.

The main difference between CDS and our custom board is in Flash Configuration.

Our custom board has 128MB Flash?

Which locations i have to change?

i configured the MPC8548CDS.h file (Flash location) but when i program and run, the u-boot is getting struck at 0xfff80e00 location? (this is checked using "ti" command in BDI).

What could be the problem?

How can this be debugged?
