Re: Kerenel crashes every other Boot..

Hi Ravi,

my first guess would be that there is a problem with your RAM. Could be
the RAM timing or just a bad RAM chip.

Try to run the image on another board, see if it works there. If not you
can check the RAM timing. Given that you have a custom board there could
be some design issues.

Where are you loading the image from? Maybe there is a problem in
transferring the image into RAM so the image download corrupts the data?

Cheers,
   Wolfgang

Hi Ravi,

you need to provide more information, for example, where does the kernel
crash, any serial console output that you see when it crashes, etc.

Cheers,

Hi All,
    I have a PPC 405EP custom target. I based most of my software on the
EP405 Taihu reference and now I am able to load the 2.6.21 kernel and
with a minimum initramfs I also get the busy box prompt. I see a strange
poblem it fails(linux crashes) every other boot. Can any one please tell

Hi Wolfgang,
     The image is getting loaded from the flash. I am able to hook up 
BDI2000 and dump various locations.
I dumped first few kilo byte locations of the image and looks no 
corruption.
I also tried this on another board and l see the same behaviour.

Also the board I am using is an existing product but it is running 2.4.18 
kernel.
Hardware of our next gen product will be based on the existing board but 
it will run 2.6.21 kernel.
So to speed software development I am using the existing product as the 
refernce and trying to put 2.6.21.

Other paculiar thing that I have seen is Once I reset the power to chasis 
or pull the card out and put it back in  it gets stuck at "Now booting the 
kernel" stage and upon hooking BDI2000 it looks like it hangs in 
early_init function at the call to memset_io(PTRRELOC(&__bss_start), 0, 
_end - __bss_start). Only way to get it back working is by burning a 2.4 
kernel rebooting the card and again burning the 2.6 one..Any idea what may 
be happening.....

The only difference i see in 2.4.x initial code and 2.6.x init code is the 
wired tlb setup in head_4xx.S. Do you know why the wired tlb setup code 
got removed from 2.6 ??

I don't have a config file for the Taihu, but I attached one for a board 
that's quite similar to the AMCC Taihu. Needs some small changes perhaps. 
Just give it a try.
