[microblaze-uclinux] Adding SPI Driver causes Kernel to Hang

[Matt Staniszewski <matt.staniszewski@xxxxxxxxx>]

Hi everyone,

I'm trying to add an SPI core to my hardware design so I can develop with an SPI DAC within uCLinux.  I'm using a S3E500 and I've added the SPI core to the default reference design using instructions provided to me by a collegue who had this booting before.  However, when I load the new download.bit file into the board, kermit shows that the board gets hung up and never boots the kernel:

At this point, it stalls.  What is wrong?  Thanks.
