Create a project for your Spartan6 in ISE, Add your code(If your code contains all modules which are required to get the expected results) in ISE ,specify all constraints in UCF ,add UCF to ISE project and then generate bit file for your device..use jtag to Program the bit file in to FPGA.
If a circuit contains more than one device that supports jtag, they can be linked together to form a 'jtag Chain'. In a jtag chain the data output from the first device becomes the data input to the second device; the control and clock signals are common to all devices in the chain. If your design uses multiple devices (...)
Hello, This typically means that there is a problem in the interface between the FlashPro and the target. Flashpro is applying both an IR (instruction Register) check and a Data register check (DR) and both are failing. It is a bit cryptic, but typically, all FFs typically would mean that one or more of the (...)
Hi I am using Chipscope 7.1 and I have a VirtexII xc2V6000 with a instruction width of 6 bits. I have a design for which I had automatically generated a jtag Controller. I can successfully sythesize the design as well as the jtag TAP. The problem is just that when I use ChipScope Pro with to connect to the device it tells (...)
NO! :( jtag is just a 5 pin interface (trst, tdi, tms, tdo,tck) . You will not come to know anything ! What I would do if I where you was this. Scan-in the data you want to send twice (whole vector not bit by bit) . Let me try explaining by example, Suppose I want to scanin 8'b01011011 . First configure the instruction register to choose the righ
jtag and Thumb are two topic, for arm. ARM internally support jtag for debug/trace purpose, such as multiICE, ETM/ETB ... THUMB was one of instruction sets(ARM-32bit, THUMB 16-bit, JAVA-8bit). When the sytem bus-width is 16bit, using thumb will be much more effective. Any way, refer to document in arm website (...)
The folowing instruction is a sample jtag for sammy9500 and for educational use only: To programm the flash in Samsung 9500 first of all you need to make a little interface, which will allow us to connect CPU with the flash inside of the receiver. jtag adapter has to be made exactly like the scheme (...)
I hava a problem about Jrunner. I want to use Jrunner ,and I can let data put into boundary scan cell by "SAMPLE" function. Now I want let data can go into logic and sample the output data. But , no "INTEST" instruction in my @ltera device. Can Jrunner use "INSTSET" ? So what can I do ? Let data can from cell to logic? Thanks.
