Hi,
I am trying to install the Segger OpenSDAv2.1 firmware on a FRDM-K82F platform. I'm having an issue getting the board to mount in BOOTLOADER mode, after holding down the reset button and plugging in the board. These are the steps I am doing:
The results after doing this are that the board mounts as "MBED", not "BOOTLOADER". I am working on a Windows 7 Pro VM, with the most current Segger J-Link software, KDS, and KDS Add-On for the FRDM-K82F. Any ideas of what I might be doing wrong?
Thanks,
Chris

Hi Chris,
Make sure jumper J23 is on pins 1-2. On some early versions of the board this was incorrectly installed on pins 2-3 instead.

Hello Chris,
Please do as these steps:
1.Press and hold the Reset button,
2.Plug in a USB cable (not included) between a USB host(PC) and the OpenSDAv2 USB connector (labeled “SDA”)
3.Release the Reset button
Have a great day,
Alice Yang

Hi Alice,
Thanks for the reply. When I try the steps you listed, my FRDM-K82F board mounts in Windows as "MBED (E:)" instead of "BOOTLOADER" as the documentation states it should.
Thanks,
Chris

Hi Anthony,
Good catch! That was the problem. J23 was on pins 2-3 for the board I had on hand.
Thanks,
Chris
