Hi Boris,
When you are running the memory test make sure Data cahe and Instruction
caches are enabled.
Also check your BAT setting, there also Cache enable BIT shall be set.
As the burst transcation will happen only when cache is enabled.
How abt ECC...?

Hi,
You could call *io_block_mapping* function from your setup.c file that will
add the entry into MMU.

Hi,
All the new development is happening in arch/powerpc architecure. So it is
good to use this architecure if you are upgrading the kernel. But it might
not work with kernel 1.1.2, As arch/powerpc need a structure like open
firmware for the parameters.
If you want to stick to 1.1.2 u-boot ver
Hi,
We need to findout where is the bottlenect.
1. Run vmstat on the ML403 board and find out the percentage CPU is busy
when you are transferring the file. That will show if cpu is busy or not.
2. Run oprofile and find out which are the routines eating away the cpu
time.
Once we have data from
nction one in each trial. But in none of them it jumped to interrupt
handler.
Please let me know whether this is the one you said to try or anything
else. ?
Thanks

Hi Sudhir,
From the PCI dump it looks like IRQ PIN register is 0. During enumeration
when BIOS sees that IRQ PIN register is 0, it would not allocate any
interrupt for this card and that's why you are seeing IRQ Line register also
as 0 value.
We need to do some work around for this.

Hi Johan,
From the pci log it looks like that BAR registers are not mapped properly by
the BIOS/U-boot. Looks like you have 3 BARS which are asking for memory, But
that are not spaced apart propoerly. Mean physical address difference
between BAR0 and BAR2 shall be 512 Megabyte, but that is not
Hi Leo,
Looks like your system is unstable when the cache is enabed. It might have
nothing to do with generic RTC driver.
Can you run cachebench or another memory benchmarks tools on the system and
see if memory sub system is OK.
