Re: [microblaze-uclinux] Spartan3E 1600E u-boot problem

["Tommy Kamps" <tommy.kamps@xxxxxxxxx>]

Hi Giulio,

I have had similar problems with the Spartan 500 starter kit, which I
have managed to solve in the following manner:

1. Do you actually have the buttons enabled in your hardware design?
If not, you have to turn it off manually in your uClinux
configuration. In 'make menuconfig', go to 'Device Drivers ->
Character devices' and turn of 'Xilinx OPB GPIO Support' This will
disable GPIO support in uClinux for all GPIO devices in your design.
If you do have them enabled, it is caused by a #define mismatch in the
driver. Read section 3.1 from this document
(http://www.google.nl/url?sa=t&ct=res&cd=1&url=http%3A%2F%2Fwww.tramhungchau.com%2FELS%2FPetaLinux_v4.pdf&ei=s83gR_7LHov2wwG_7-nJCA&usg=AFQjCNHTrHfjR3O2Owe1nePnRKFMAvMArg&sig2=DE8PBJ3OLovS2fWQ8uzwXg)
for a solution.

2. For this problem, I will probably need some more information, but I
am not sure that the way you try to load the kernel is correct. I
recommend starting by loading the kernel through the XMD debugger.
Start XMD and connect to the microblaze. Then download the image.bin
to the start address of the DDR_SDRAM memory. (dow -data image.bin
$SDRAM_BASEADDR). When this is done, tell XMD to continue from that
address (con #SDRAM_BASEADDR).
If you want to boot your kernel from flash, I think you will have to
follow the steps described in the tutorial, rather than just sending
the srec image to the terminal.

Regards,

Tommy Kamps
