Description Blake Leverett 2014-12-02 21:07:22 UTC

I emerged openocd and it failed to detect the cmsis-dap adapter (Atmel Ice).  It connected OK after I added these flags to the ebuild: 
 --enable-maintainer-mode
 --enable-cmsis-dap
 --enable-hidapi-libusb

My use flags:
dev-embedded/openocd-0.8.0  USE="cmsis-dap ftdi parport usb verbose-io -dummy"


Reproducible: Always

Steps to Reproduce:
1. Build openocd
2. Try to connect to remote cmsis-dap device 

Actual Results:  
openocd fails to detect the device

Expected Results:  
Device should be detected

Comment 1 Paul Fertser 2014-12-03 08:24:33 UTC

Blake,

Both --enable-maintainer-mode and --enable-hidapi-libusb options are not present in OpenOCD's configure so they can't have any effect. --enable-cmsis-dap should have got added automatically since you have cmsis-dap use-flag. Also, cmsis-dap support is autoenabled anyway, provided you have hidapi library installed, and cmsis-dap useflag adds it as a dependency.

So please check twice what happens when you build with cmsis-dap flag. On my system it properly outputs "CMSIS-DAP Compliant Debugger            yes" at the end of configure. And then please also provide openocd invocation log as "failed to detect" might mean it doesn't see it on USB bus (e.g. a permissions issue) or it might mean openocd says "cmsis-dap transport is not available".

On a slightly related note, this patch: http://openocd.zylin.com/#/c/2356/ should improve cmsis-dap performance a lot but it's known to have issues with Atmel's implementation. If you feel like hacking on it, it'd be great, as it's likely missing just a small tweak to start working properly.

HTH
