I had a Platform Configuration Error while using the Arm Development Studio 2023 program with DSTREAM-ST equipment.
My FPGA(XCVU19P) Board is connected to CORESIGHT 20 cable of DSTREAM-ST equipment.
Error content is as follows.
"Scanchain detection failure : Detected number of device =136, maximum allowed = 128.
This problem is usually a result of the scanchain not acting correctly when using JTAG scans to count the number of devices."
I want to know the cause and solution of the error.
I thank you in advance for your reply.
I recommend you raise an official support case from the Support menu above.
