[U-Boot-Users] Uboot for ppc 405GP with vision probe

[Thanh Nguyen]

Hi all, 

I'm in internship. It is the first time I use Uboot. I have to load the
uboot binary in the flash (AMD 29VL461DH - 8MB - PPC 405GP) with vision
Probe. But I got this error message from vision probe each time it tried
to load the binary :  
"Unable to communicate with the emulator. Please check the physical
connection and use the terminal windows..."

I use the lastest version of Uboot : 1.1.4.  With the old binary (uboot
0.4.0), it works correctly. Thats why I think there is something wrong
in my configuration walnut.h. I will appreciate a lot if anybody can
give me a solution of this issue. 

Thanks a lot.

Please contact WindRiver technical support. This is off topic here.

Yes, it's a technical challenge, and  you  have  to  kind  of  admire
people  who go to the lengths of actually implementing it, but at the
same time you wonder about their IQ...

If it truly works with 0.4.0 and not with 1.1.4, I would speculate that 
your memory map with 1.1.4 is not compatible with your hardware... 
either your 1.1.4 image is in a different location or it is bigger.

Check your image sizes and locations (objdump for elf, less (the program 
;-) for S-record files, xxd and some luck if all you have is a 
VisionProbe binary lump).
