I have two FRDM K64f boards, and I am trying to get CAN communication to work between them, and now one of my boards when I try to program it says that there is a failure in launch sequence. In order to program both boards, I was unplugging one of the boards, so I could program the other, which I think may have to led to this, but I'm not sure how to fix this issue.
Also, if you know how I could program both boards without unplugging one of them that would be helpful as well.
Hi Timothy,
you have to specify different port numbers for each connection, see Debug Multiple Boards with GDB at the Same Time | MCU on Eclipse . Then you can debug multiple boards the same time.
I hope this helps,
Erich
Hi Timothy Smith,
You can try the Segger JLINK's method: multiple devices in the scan chain.
More details, please refer to this document:

Page 180, chapter 5.3 JTAG interface.
Wish it helps you!
Have a great day,
Kerry
