Hello,
We have recently ported uboot1.1.2 to our propriatery mpc852T board in
50 Mhz and it works fine.
but in 100Mhz version of the same board, the linux crashes with output
below. We are only changing the CONFIG_8XX_CPUCLK_DEFAULT 50000000 to
100000000 with the mptpr value to ensure refresh cycles of the sdram.
we have adjusted the refresh timing of the sdram to 12.5 us successfully
but the linux keeps crashing. We have also tried the different versions
of the eldk but it keeps crashing at the same place. The board passes
from the dram test in uboot.
we using micron 48lc4m32b2-7 as 2 banks. Can upm ram array cause problems like these or
Where can be the problem ? If you can help we will be very appriciate.
Thank you.
Best Regards
Yiğit Can
