Peter, Thanks for additional info. I made up 26 lead ribbon cable with two IDC26F connectors tonight and did some more testing. 1. New cable did not make any difference in firmware loading or communication b/w host PC and 7i43 card. 2. Write eeprom via eepio8-2.bit(DOS) and usbio8-2.bit (USB,win2000) using both SV8S.BIT and eepio8-2.bit alternately. 3. In all cases, eepio8-2.bit was successful and card reset with W4=up W5=down (load from eeprom) the FPGA started and ran continuously. Tested FPGA operation with rpo.exe and every connection would produce 50504555 and response from test LEDs. 4. SV8S.BIT didn't respond correctly after writing via EEP or USB to eeprom. In both cases with W4=up W5=down (load from eeprom), readhmid 0378 would produce "No hm2 found". Additionally, hm2_7i43 produced the normal "invalid cookie" "-1 invalid parameters" errors. One exception: DOS (W4=down W5=down load from epp) >sc7i43p SV8S.BIT 0378 >readhmid 0378 Responded correctly, listing hm2 config for about 30 sec after epp loading. On repeat command: >readhmid 0378 "No hm2 found" It seems that with SV8S.BIT, 200K FPGA is hanging or developing a "runtime error". 5. So, has anyone got 7i43 200K board working with hostmot2 firmware, SV8S.BIT or SVST4_4S.BIT? Thought I'd dig into the xilinx webpack tonight, but wow! version 10.1 is now at 2.2GB download. Grabbed it anyhow. Read thru the cable stuff and Peter, now I understand what meant by "Parallel Cable IV or parallel cable III or Xilinx USB cable". Last March I grabbed ISE webpack 9.2, started installing to debian, got bogged down and never learned about the "cables". Thanks for the offer on the PCB. I'll try to get the webpack installed and get back to you.
