Re: [OpenOCD-devel] [PATCH]: e2492ac Added OpenJTAG Driver

[Ryan C. <cor...@gm...>]

David,

Here is the openjtag configuration file that is included in the patch:

interface openjtag
adapter_khz 6000
openjtag_device_desc "Open JTAG Project"

The available speeds are listed in the Open JTAG protocol manual.

Thanks,
Ryan Corbin
