I suggest you take a magnifying glass and read the microcontroller model. With the model you will be able to find the datasheet on the Internet. Take a look at the PIN out of the microcontroller, and see how many JTAG outputs it has.

Depending on the version of JTAG/boundary-scan, two, four, or five pins are added. The four and five pin interfaces are designed so that multiple chips on a board can have their JTAG lines daisy-chained together if specific conditions are met. The two pin interface is designed so ...

Sometimes, if you only have a very low power supply, when you connect your JTAG cable, the voltage drops to a level that is not acceptable and that is when you get this kind of errors. – FarhadA. uk pensions telephone numberWebPractical Example: Determining Instruction Length with UrJtag. While OpenOCD is excellent for interfacing with DAP controllers and connecting to debugging cores, the UrJTAG project is great for interfacing with JTAG at a low level. We can use this to detect the various DR lengths with their useful discover command. This method uses the same principles … uk pension state amountWebThe ZedBoard JTAG chain was designed to allow the FMC JTAG chain to be inserted into the scan chain which would allow for things like Boundary Scan Test or In-Circuit Programming of FMC devices.
