unable to find a matching CMSIS-DAP device

[wdevore]

I can't seem to load the basic Blinky example via the board's DAPlink. I can upload to the Pico directly just fine but not with the baseboard. This is the error i get:

I noticed that the product-string (above) doesn't match what ``dmesg says (below):

I tried manually putting the serial number in the cmsis config file but that didn't help.

Thoughts? I'm on a Linux box.

Thanks.

hello, try add sudo before your command

Instructions for linux using openocd 0.11.0

1 when compiling, you need to add support for cmsis-dap 
 $./configure --enable-cmsis-dap
2 add 2 lines to cmsis-dap.cfg
cmsis_dap_backend hid
transport select swd
3 command for reference
$sudo ./src/openocd -s tcl -f tcl/interface/cmsis-dap.cfg -f tcl/target/stm32f1x.cfg

After researching more I found what I think is a mistake in the cmsis-dap.cfg file. It appears to have spaces in the cmsis parameter:

cmsis_ dap_ backend hid and it should be cmsis_dap_backend hid

Once I fixed that it seems to find my device based on the serial number:

sudo openocd -f interface/cmsis-dap.cfg -f target/rp2040.cfg -c "program test_project.elf verify reset exit"

Yet it still fails!

This is my .cfg file:

#
# ARM CMSIS-DAP compliant adapter
#
# http://www.keil.com/support/man/docs/dapdebug/
#

adapter driver cmsis-dap

# Optionally specify the serial number of CMSIS-DAP usb device.

#cmsis_dap_serial 0700000100420019390000084e50364aa5a5a5a597969908

cmsis_dap_backend hid
transport select swd

Why does it error on both the CLOCK and JTAG when the .cfg file says swd ????

I even tried stm32f1x.cfg as the target and it still fails:

sudo openocd -f interface/cmsis-dap.cfg -f target/stm32f1x.cfg -c "program test_project.elf verify reset exit"

Hello, please check the wiring and power supply, The log shows that the DAP itself is OK, but the target chip is not detected (usually a wiring problem)

hello, try add sudo before your command

This works for me. Is there a group I could add the my user to (in my case it's impractical running openocd as root)? It seems like (at least in my case) a permission problem.
