I have updated my J-Link EDU (hardware V9.30) to the latest firmware version V9 compiled Jul 29 2016 18:50:09. With this new firmware, OpenOCD V.0.9.0 doesn't work anymore (see log below).

How can I go back to the firmware version V9 compiled Sep 18 2015 19:53:12?

Thanks in advance

Hi Niklas,

I just did it, but unfortunately the V6.00d still contain the firmware from Jul 29 2016.

Cordially,

Daniel

Hi Niklas,

I downgraded the firmware according to your recommendation to the J-Link release V5.12j, which contains the firmware APR 22 2016 and everything works fine again.
Many thanks for your support.

Cordially,

Daniel
