KMS won't connect to kv31f board.

All I get is "Could not verify communication over port", I have tried multiple different bootloaders, the openSDA serial port shows up in device manager. The SDK is installed. I installed KDS 3.0 as a few posts said it doesn't work on 3.2. I did manage to connect in KDS and flash one of the example projects via debug. Now I don't know if it preserved the motor code as documentation offers little information beyond saying not to erase it. The board actually had the mbed bootloader when I first used it, is it supposed to be configured like that? None of the KMS documentation had anything about having to replace the mbed loader. I looked to see if there were multiple kv31f variants but they all seem to be the one that should have the motor control software.

Jacob,

Have you been able to contact Mouser and get a replacement board?

The other option I can offer is to do the re-programming of the debug and the KMS library here at NXP or I can do an exchange with you.

Let me know how you want to resolve this.

Best Regards,

Philip

The  board you have indicated is shipped with MBED bootloader, means that it may not support KMS.  It's a FRDM board, correct? And did it have the Freescale packaging? If it had the NXP packaging then there is a problem.  We re-programmed all of the units in our warehouse with the FRDM-KV31F bootloader and debug interface, Not MBED.

I'm positive that KDS 3.0 without the P&E Micro eclipse updates does a mass erase.  So however you got here the KMS library is probably gone.  I'm not clear from your description whether you have completed all of the eclipse updates. 

Coming soon will be a version of KMS that is compatible with KDS 3.2 (also needs eclipse updates).

If you want to do KMS sounds like you need to get a new board.  From whom did you purchase the board ?

Hi Jacob,

I've done a little digging.  There was a shipment from Freescale to Mouser of 3 ea FRDM-KV31F board that did not get the re-work we did in February.  You must have received one of these units.  The board you have is not KMS enabled.

Please contact Mouser and ask for a replacement.

I apologize for the incovenience.

Regards,

Philip

They sent me another, should be here tomorrow. Thanks for the help.

Are there any plans for a more permanent versions for the KMS software? Ti have their's in the hardware, STM just have a precompiled library, making it impossible to replace by the user is not good if the device must be flashed for some reason.

The replacement is the same batch, same issue MBED firmware. Were the non-KMS ones recalled or distributors notified of the ones missing KMS?

Hi Jacob, as Philip states, this batch of boards appears to have slipped through the final stage of prep when loading the KMS library to the flash.

I'm really sorry for the inconvenience this has caused you.

Please send me a email directly (available from my profile) with your shipping address and I'll ship you a new FRDM-KV31F board with the correct programming.

sincerely,

Mark

Hi Mark,

Did you receive my shipping details in the email I replied to? I though maybe it was just in transit but nothing came this week.

I'll check.  I'm looking for a resolution to the issue. Yes we did inform each of the distributors. What I might do is swap the boards with you. I'll be in touch today.
