FRDM-K64F Revision E3 not working

[intertronic]

Hi everyone,

we are using two different versions (D1 and E3) of the FRDM-K64.

Booth are loaded with OpenSDA V2 and we use the KDS 3.

But with the E3 the usb-connection/debugging with the desktop is not stable. Sometimes it runs for 20 minutes, sometimes it hangs after 3 steps.

Does anybode else has such problems?

Regards

Hello intertronic,

please, have you tried to reload open sda firmware on the FRDM-K64F ?

On my side is running FRDM-K64F - schematic E3 revision without some problems.

In other case, is it possible for you to attach screen of the error?

Best Regards,

Iva

Hello Iva,

Problem seems to be solved.

The problem was, that the USB seems to break down. We used the OpenSDA

version 2 with a version from last year which was working with the old

FRDM-K64F. further we used the version 2015-04-23 which doesn't work. We

found a new version 2015-06-11 which is working with the new FRDM-K64F...

Thanks, Josef
