Hi,
if i want to use "Platform Configuration" for DSTREAM-ST in DS5,
i recevive this "Scanchain detection failure: Detected number of devices = 1.024, maximum allowed = 1.023. This problem is usually a result of the scanchain not acting correctly when using JTAG scans to count the number of devices."
Can you help me please to resolve this problem.
I want to test Cortex M33 from NXP (MIMXRT685_EVK)
Thank you in advance.

Hi Stephen,
thank you for your answer. I use now the ARM Dev. Studio 2021. I have the same problem after update.
in DS 5:
in ARM Dev. Studio 2021:
i recevive this "Scanchain detection failure: Detected number of devices = 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."
Thank you in advance
Hi AbdelillahThanks for updating to Arm DS. Sorry, I don't have access to that board to be able to try it myself, but I'm surprised that you see a different error message with PCE.However, you probably don't need to use PCE for the MIMXRT685, because this device is already "known" by the NXP CMSIS Pack - see screenshot. Please try selecting one of these ready-made configs instead of using PCE?
If that does not resolve the problem, please open a Support Case using the "Support > Open a Support Case" option at the top of this page, so that Arm support and engineering teams can properly investigate.Hope this helps,Stephen
