Raul, If you are referring to the Memec
Spartan-3 MB board with XC3S1500, I don’t believe there have been any
changes. The boards are all tested before customer shipment, but you can
download the functional test and test it yourself if you are suspicious about
the board itself. You can get the support files for all Avnet/Memec boards
from www.em.avnet.com/drc. The
specific link for this board is: The error below is indicative of a memory
problem. I would test the DDR on the board and then closely inspect the
timing report for the design from which your download.bit was generated.
It is possible to have a marginal design that works fine on one board and fails
on another due to the FPGA and DDR chips themselves being closer to their own
specification borderline. Regards, From: owner- Hello, I just received two new demo boards: Memec Spartan-3
development board. I download FPGA program with EDK, I launch xmd, and I
load successfully image.bin to RAM with “dow –data …”. When I make “con 0x22000000” to start
uClinux xmd gives next error: XMD%dow –data /tftpboot/image.bin 0x22000000 XMD%con 0x22000000 Processor started. Type “stop” to stop
processor. RUNNING> XMD% ERROR: MTD – MicroBlaze Pipeline Stalled
executing Instruction at >> PC: 0x2211eca4 Try Resetting the Processor to Continue.. XMD% Strangely, using the same FPGA program(download.bit)
and image.bin on our old MEMEC boards, it works! May they have changed something on the board? Some help? Thanks. Raul Camaras |
