Re: [OpenOCD-user] how to use with EFM32 STK

[Peter A. B. <pa...@pa...>]

OK, good point.  Not sure how I got it in my head they were the same 
thing; probably just assumed EFM32 support meant support for the 
on-board debugger on the EFM32 eval boards.

As far as I can tell, the jlink driver forces selection of JTAG because 
it doesn't implement SWD, resulting in the error below since the 
on-board debug interface only supports SWD.  So this isn't going to work.

Thanks for clarifying this; sorry for the noise.
