Could not find CFI complaint flash device

armaram — Sun, 01 Oct 2017 05:17:44 GMT

While re-programming our KM34Z256VLL7 we get the message 'Could not find CFI compliant flash device".

I tried all options, power cycling, multiple resets, unlock kinetis, etc. but nothing seems to work.

Can anyone please help? Following is a screen shot of the error and also attached is a log file which might help you understand the problem better.

I tried programming the device using a PE micro Universal FX cable. Following is the console log, this might give you some more info on whats happening..

Sorry for the late reply!

According to the KDS_Release_Notes, it seem's that KM34Z256VLL7 is newly supported in KDS3.2.

If you set the Debug Configurations of KDS3.2 like below, will the problem still happen?

Best Regards,

Robin

I got the same message and the problem was the MCU not begin correctly set.

Go to Options > Project Settings > MCU

Then click on the "3 dots" to choose the correct Device.

Then close with OK, and it should work.
