I am a Ubuntu 16.04 development host and installed the Segger tools. I have connect the eval board port J28 and the mass storage device appears. I can load up designer loads by dragging and dropping. All settings on the board are default and it is using HyperFlash. When I try to start the JLinkGDBServer it does not see the target. What steps am I missing? 

Here's my "DETAILS.TXT"

After loading OpenSDA 2.1 the Segger gdbserver now connects and works find. But now my mass storage flash downloader no longer works... What is the best way to download to flash when running OpenSDA 2.1?

Hi,

after you upgrading OpenSDA interface. What's your GIT SHA number and SDK version?

they must match each other.

If you use latest OpenSDA, you need use SDK2.3.1 or later.
