Hi,
I'm trying to test out a new ML605 (rev D) evaluation kit and the BIST demos that came with the compact flash card to verify board functionality. None of the demos have worked at all so far. I followed the instructions when first starting up the board - setting DIP switches, installing + configuring the USB-to-UART bridge/Tera Term - in the Getting Started guide UG533. I set my port to COM2, and TeraTerm can connect to it, but no output shows up. I have a VGA monitor connected to the board as well to test DVI/VGA output, but that's always blank.
I tried reloading the compact flash card with contents of cf_image from the design files (rdf0017_13.1_c.zip), but no luck. I also used Impact to "download.bit" from the ready_for_download folder. Impact programmed the FPGA successfully, but still the demos didn't work.
After that, I followed the ML605 BIST guide (xtp056_13.1_c.pdf). I used SDK to program the FPGA with the system.bit file, the system_bd.bmm file, and initialized "bootloader" as the ELF in BRAM. It loaded successfully but still nothing. I tried connecting with xmd:
XMD% connect mb mdm

ERROR: MicroBlaze is under RESET. Check if the Reset input to MicroBlaze and its Bus Interfaces are connected properly
UNABLE to STOP MicroBlaze
The RESET error worries me. But when I try to connect a second time, I get:
XMD% connect mb mdm

ERROR: Could not detect MDM peripheral on hardware. Please check:
1. If FPGA is configured correctly
2. MDM Core is instantiated in the design
The mdm shows up in the system.mhs file connected to the plb and microblaze debug buses. I'm not sure what the deal is with the RESET error, or why it doesn't show up the second time. I checked the system.ucf file, it has
Net sys_rst_pin PULLUP;
Net sys_rst_pin LOC= H10 | IOSTANDARD=SSTL15;
## System level constraints
Net sys_rst_pin TIG;
and the active high reset agrees with the ML605 Hardware User Guide (UG534, pp 49-50).
I'm using all 13.1 tools on Vista 64-bit machine. I'm assuming the TeraTerm is connected to UART properly because 1) the SiLab USB-UART bridge shows up in my device manager and 2) TeraTerm doesn't complain about connecting to the COM port. I'm also fairly sure the CF is loading properly (the SystemACE status LED blinks at startup and then stays solid green). It's a 2 GB card by Transcend with FAT format (came with kit). Also I have Production version Virtex 6 FPGA (Manufacturer's ID = Xilinx xc6vlx240t, Version : 6) so I'm using the right design files ("C" and not "CES").
Any help on this would be great, I'd really appreciate it. Just running the startup demos is eating up design time...
Thanks!
