Hi all,

 

I am trying to use LPC-LINK2 and openocd under ubuntu 16.04 recently. LPC-Link2 has been programed with JLINK firmware.

openocd:Open On-Chip Debugger 0.9.0 

board:lpc1837

I used the command to connect with the board: openocd -f interface/jlink.cfg -f board/lpc1850_spifi_generic.cfg

However it got the following errors:

adapter speed: 500 kHz
cortex_m reset_config sysresetreq
Info : J-Link LPC-Link 2 compiled May 30 2016 16:15:37

It seems that there is no any differences with lpc1850 and lpc1837 in configuration file.What is wrong with it? What should I do next?
