In-System Programming with Cyclone III

Thanks for the feedback again. That is very useful to know that JTAG mode sort of overrides what MSEL has been set to and certainly saves me time from having to switch those darn jumpers every time I go to program the FPGA. Thanks also for clearing up that issue with VCCA and the 'configuration voltage'. I beleive that my configuration device is a 3.3V device but as you pointed out, this is separate from the MSEL voltage itself. I'll have a look at the nSTATUS, nCONFIG and CONF_DONE pins and get back. Unfortunately for this project, it is a home brew thing so my hours dedicated to solving these issues are minimal and my equipment at home is either broken or non-existing. Your suggestions are a great place to start once I get organized! Thanks again,
