MIMXRT685 DS5 and ARM Development Studio with DSTREAM Debugger

[Abdel]

Hi, i want to connect the MIMXRT685 (Cortex M33) either in DS5 (v5.29.3) or in ARM Development Studio 2021, but unsuccessful. I used as Debugger:

DSTREAM ST/PT Firmware 7.4..0-3i in ARM Dev. Studio and

DSTREAM ST/PT Firmware ARM_RVI_4.34.0-132.

I get these errors:

In ARM Development Studio 2021 :"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"

In DS5: "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 to reslove this problem.

Thanks in advance

Hello @Abdel,

I'm not very familiar with the DSTREAM and I think the correct place to post this question is one of the ARM communities.
