Hi, I’m sorry but I’m not the
correct person to ask if uclinux fails during booting. Insight into uclinux is not my strong part.
I don’t have time for learning that. I’m too busy designing new
MicroBlaze versions. There must be others on this mailing list
who can give more insight into the cause of your problem. Göran From:

[mailto:owner-microblaze-uclinux@xxxxxxxxxxxxxx] On Behalf Of Goran Bilski 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. Göran From:

[mailto:owner-microblaze-uclinux@xxxxxxxxxxxxxx] On Behalf Of Venkatesha 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 |
