Windows11: OpenOCD from MSDK cannot initialize the MAX32625PICO CMSIS-DAP

[rhempel]

On my corporate managed Windows11 laptop, the OpenOCD from the MSDK installer will not open the MAX32625PICO CMSIS-DAP device.

On the same laptop, a VirtualBox VM that we attach the same PICO to as a USB device will work under OpenOCD and PyOCD

At this point I'm not sure if it's a general Windows 11 issue, or if it has to do with the corporate management of USB devices - long story short is I can't do any work with the MAX32690FTHR board until this is working.

I can work around it using a Linux laptop but ideally I would like to use a standard (if somewhat locked down) Windows11 device.

@rhempel I can confirm that our toolchain should work on Windows 11. I have been using on my home machine successfully.

The error log seems like permission issues on the USB port. You will need USB read/write access on the machine to connect to the PICO. I suspect IT has locked this on your managed machine. If you can write a file to a USB drive you should have equivalent permissions to connect to the PICO.

The "could not open device" messages are standard as OpenOCD iterates across all the USB devices it can find. The device ID for the PICO is 0x0d28:0x0204, which it is finding successfully during the scan. I've attached a log from my W11 machine for reference.

They key errors in your log are

• could not open device 0x27c6:0x63ac: Access denied (insufficient permissions) - indicating permission issues on a different USB device
• Error: 105 424 cmsis_dap.c:293 cmsis_dap_open(): unable to find a matching CMSIS-DAP device - indicating OpenOCD failed to open the device. This is the same message thrown if there's no PICO connected to your machine either. Since the scan chain is at least iterating across the end-points I think this further confirms a USB permissions issue.

Thanks for the reply @Jake-Carter - I believe it does have something to do with permissions, but it's not read/write permissions on the USB drive. I have an IT-exception for this on my machine, and I can confirm that I am able to create, read, and modify files on the exposed USB drive for both the DAPLINK and MAINTENANCE modes of the PICO.

I understand how the enumeration scan works for OpenOCD and have looked at the AD fork of the source.

Is there a possibility of adding some additional diagnostic output for the -v option when OpenOCD tries an operation on the 0x0d28:0x0204 device? The enumeration works so there is some other operation failing when it tries to add it to the list of valid CMSIS-DAP devices.

By the way, the command line I am using to open the device is:

C:\MaximSDK\Tools\OpenOCD\openocd.exe -f interface\cmsis-dap.cfg -f target\max32690.cfg -d

I can see in your log that cmsis_dap.c functions are getting called, and that's missing on my side.

Is there an additional driver/dll that OpenOCD needs to work on Windows11?

[Jake-Carter]

Hmm, generally if you can write to a USB drive you shouldn't have any issue with the PICO.

Here are my driver details (Device Manager -> View -> Devices by container -> DAPLink CMSIS-DSP)

Key drivers to check are DAPLINK and WebUSB: CMSIS-DAP. Do these match?

[rhempel]

The main difference is that I am missing:

• HID compliant vendor-defined device
• USB Input Device

The WebUSB driver I have is slightly different:

I have opened a ticket with our IT provider - there are some posts on the web that indicate CrowdStrike may be interfering with some USB endpoint devices. This kind of makes sense, so I'll follow up on this when I hear back ...
