RE: [microblaze-uclinux] error when compile

Yes I manually changed the sram address to 80000000 in EDK. So should I change the D/I cache to be 80000000 also is what you are saying right? Here’s my question must the SRAM address be 80000000 or can it be anything but it has to have at least a 4MB range right?

Hi Eric

I just check up your mhs file, there is one thing, i don't really get how it works.
The mhs shows the I/D cache address from 0x20100000 to 0x201FFFFF and there is no device that mapped to 0x20100000 to 0x201FFFFF. This is why you getting pipeline stalled error.

Normally D/I cache should map to memory device. The only memory device is SRAM_256Kx32 and mapped to 0x80000000 to 0x0803FFFFF. Did you manually SRAM_256Kx32's address in the mhs file? or this is generated by edk bsb?

I think it will be a good idea that you recreate your hardware platform and kernel image, both auto-config.in and mhs shows wrong mapping address for I/D cache.

Regards,

Jason

Hi John thanks,

I haven't done the cvs update yet but I took the image files that were

created and I'm still having problems getting the kernel to boot.  I've

enclosed my auto-config file which I have used to make the kernel now and

now after running dow -data image5.bin 0x80000000 and con 0x80000000, I get

this error Microblaze pipeline stalled executing instruction at >> PC:

0x80000000c. Try resetting the processor to continue.  I tried to follow

Emile's document on changing the testmem.c file and changing the microblaze

version from 4 to 3.00. Should I do that or is that unneeded.

Hi Eric,

I have no idea why this happened but I commented out in mmap.c under the

mmnomu directory this section calling for a romptr and I was able to build

the image.bin and elf files.  Any ideas on what this code was doing?

OK, so this one's beyond your control :)  There's been some work going

on in the MM part of the CVS lately, looks like microblaze got affected.

Change to uClinux-2.4.x/arch/microblaze/platforms and do

$ cvs update Rules.make

That will pick up a one-liner fix that I just committed to CVS, and you

should be back in business.

Regards,

John
