I installed Openocd from opfficial Arch Linux repositories today and am now trying to use it with my JTAG adapter ULINK-ME. I found out that ULINK-ME uses CMSIS-DAP debugging firmware. Openocd has CMSIS-DAP drivers and should therefore be able to communicate with my adapter but after I wrote the command below I got an error.
I am connecting ULINK-ME to the board EA3141 which integrates microcontroller LPC3141 - a close relative to LPC3131 for whom I load the configuration file.
sudo openocd -f /usr/local/share/openocd/scripts/interface/cmsis-dap.cfg -f /usr/local/share/openocd/scripts/target/lpc3131.cfg -d3

Does anyone know why I get the errors?
I allso tried to start it in another way but again it prints errors. A bit difrently this time.

Because there is no string "CMSIS-DAP" in it I guess it means that I have an older ULINK-ME (bought before 2013) adapter which didn't have CMSIS-DAP firmware. I hope Keil offers some way of flashing CMSIS-DAP to my older ULINK-ME.
SOLUTION:
I wrote to Keil and they claimed that ULINK-ME's firmware can be updated and it is true. They pointed me to these three links:
2. - upgrade if Keil uVision hasn't done this by itself in point 1.
3. - manipulate your ULINK-ME even further
I had to install MDK-ARM v5 on a Windows machine and then click on a very hidden icon (a magic wand) on a toolbar. There under debugging I chose the ULINK2/ME option and it updated my firmware by itself. Now I have a CMSIS-DAP on my ULINK-ME (older model) and I can confirm this with sudo lsusb -v:

I tried to do this using Wine, but it wasn't possible. At least now I don't need Windows any more.
0.8.0-dev-00175-g8b7acca-dirtyThis does not look like an official OpenOCD. Where did you get it ?Note: Your version should say
0.9.0and definitely not'dirty'.Your version of OpenOCD might have problems with CMSIS-DAP. I highly recommend you to clone the current HEAD from here:
(remember to do
./bootstrap, before you./configure ...after cloning)-Or download from Freddie Chopin's site if you're running it under Windows.
sudo openocdSomething is wrong here too. You should not have to 'sudo' each time you want to use OpenOCD.Anyway, you should be able to use JTAG (LPC3141 seems to be too old to support SWD).
