there is not much I can share (yet) but:



the impact/xps download to ML300 freezes some times, problem has been fixed by restarting rebooting, sometimes pressing the "fpga prog" button.



the fpga prog button I guess simply forces the fpga to not-init state waiting for config, as sysace is not reset, it stays in non-configured state until you configure with impact.



there are no settings on ML300 that could prevent the jtag re-config it should always work (but does not)



in my case I had started v2pdk shells, debug server debugger, killed them and then tryied impact, and was freeting, not sure why.

Please make sure that you are using the latest Xilinx Implementation tools. From the previous message I can see that you are using 5.1. The latest tools are 5.2i with service pack 3.

When looking at the schematics for the ML300 you will see that the FPGA PROG button goes to the corresponding pin on the FPGA, i.e. pushing the button will clear out the contents of the FPGA.
