Where i can get the programming sequence of CoolRunner?

I advice you to use to remote the JTAG from SVF file or a binary file of SVF if you want to remote from an embedded processor. SVF is a nice ASCII file format. Both XILINX and ALTERA pupose this format. AND the format is supported by many ATPG for Boundary Scan (Board TEST).

NOTE: the SVF is nice for downloading FPGA and CPLD or for testing PCB, but is to heavy for debugging processor !

If your are doing a commercial product, we have build our own SVF player (actually we can remote JTAG for any XILINX FPGA/CPLD or ALTERA FPGA). Written in native C, we have tested it from a PC over EPP port and from our ARM platform. (fully used by our Chameleon POD Programmer)

Contact me for more info.

Chi, we could not get through to your e-mail address. Here is what I have been asked to forward to you through the newsgroup:

"Chi, Peter Alfke forwarded your request for help on CoolRunner programming through JTAG. Can you tell me more about what you are trying to do ( which parts, what software, cables, etc. that you have). I run the CPLD applications group and either someone on my team, the Configurations Solutions team, or the hotline can give you a hand. Tell me more and I can direct the solution. Jesse Jenkins, Xilinx snipped-for-privacy@xilinx.com "

I need to program XCR3256XL and XC2C64 CPLDs'using an embedded controller through JTAG Test Access Port. In XAPP058 application note I have seen CoolRunner Programming Algorithm, but i need more details like how to initialize the device, how to set the device in ISP mode etc.,

regards, Chi

ISP mode is enabled by the pin called PORT_EN, just read datasheet.
