No access to FRMD-K64F-Board

[j_oberfell]

I use FRDM k64f-Board and the demo application is running without problems.

The problem ist, that i have no access to the board.

MBED driver is installed like descriptionin the quick start guide.

I see the MBED USB device, but if i click on it, a error message "access denied" appears.

Hi,

As Michal said you need to use the Segger J-Link OpenSDA v2 firmware, this is one of the ways to use the FRMD-K64. You may find useful these links:

I hope this information can help you.

Hi Joachim,

You can burn into freedom board J-Link OPENSDA firmware from segger's web pages: SEGGER - The Embedded Experts - OpenSDA / OpenSDA V2

If you can use segger's OSDA, you must use version 2. Version 2.1 doesn't work with frdm-k64f.
