Antwort: Re: [microblaze-uclinux] MicroBlaze restarting


thanks Raul, but my only connections to the opb peripheral are the OPB bus, and two external ports, no possible another shared pin...

Could it be possible my opb peripheral reacts to same OPB addresses like SDRAM(which is also connected to OPB bus), and that conflict makes problems??

I will look into this...

kind regards,
Raul Camaras

Hi Raúl,
 
I had a similar problem some time ago and in my case the  problem was that in the board I was using (Xilinx’s MicroBlaze Development Kit) there was a shared pin between the SDRAM and my peripheral (one LED in fact).
 
So when I added that peripheral the SDRAM crashed. Check if one of the lines than communicate with your CAN controller is shared with the SDRAM.
 
Regards.
 
Another Raúl ;-)

Hi Michal,

thank you for your mail.

Exactly, I did a memory test and it FAILED! while in the working design it passed.

I dont know how to try u-boot.

My platform is Spartan3-4000 and EDK 9.2.

Linux Version is 2.6 from  Petalinux, but I dont think this has something to do with the problem.

Clearly this is a problem of EDK, I just added an OPB peripheral, why is it having effect on SDRAM??

Kind regards,
Raul Camaras

Hi Raul,

first of all. Please never start new message from older one. Just start new.

Have you done any tests on your design?
I mean simple EDK memory test. Is it OK?
Have you tried to run U-BOOT?
What is your devel platform?
What linux version are you using?

Any console output is helpful.

Regards,
Michal
