Hello,
i have a "SABRE Board for Smart Devices Based on the i.MX 6 Series". And I tried to get OpenOCD to work with it.
This is my OpenOCD configuration file for the i.MX6. Which is included in OpenOCD v0.7-dev.
scripts/target/imx6.cfg
scripts/interface/openocd-usb-hs.cfg
I know i allready posted it on the iMX Forum but did not got any response..
Do you have any idea what's the problem? If you need further information or if i did something wrong please let me know!
Thank you! I hope you can help me!
