Hi,

Are you downloading the image.elf file or the image.bin file?

I have seen the error that you are seeing when I download the image.elf.

If I download the image.bin file I don’t see the error.

The command lines I use are as follows:

dow –data image.bin 0xXXXXXXXX

con 0xXXXXXXXX

where 0xXXXXXXXX is the address of your memory.

This may help.

Cheers,

Angela

Hi,
That will happen if you try to do a memory access to an address where no slave response to or doing a blocking FSL which will never get the correct FSL status.

Dear All,

I am able to continue till configuring and generating uClinux image.
But when I tried to download the image using XMD debugger, it gave below error.
/ERROR: MDT- microblaze pipeline stalled executing instruction at >>PC: 0x00000010/ 

/Try resetting the processor to continue../

/ /
My hardware passes memory test and also I have marked bootloop for bram initialization.
I am using EDK 8.2SP2 and Microblaze version 5.00.c. Is this configuration supports uClinux 1.00.d.? 

I am attaching MHS, MSS and auto-config.in file with this mail.

/Please help me, this is the second time I am requesting/.

Thanks & regards,

Venkatesha K
