Customer have a couple of FRDM-KV31F boards with erased KMS library.
Is it possible to re-flash MKV31F512VLL12 on board with KMS library without sending it out to NXP?
If it requires NDA or other contract, I would be happy to sign it.
Have a nice day.
Solved! Go to Solution.
Hi, Pavel,
As far as I know that that the KMS code is third party code, it is written to flash in factory. If you erased the KMS code by mistake, we can not help you reprograme it because we have not the binary code of KMS either.
Sorry for not helping you.

If the code is propietary, why not using a ROM to store that library (as TI does with their piccolo InstaSPIN devices)? I'm another stupid who deleted the KMS library without knowing (by using a board with MBED fw on the opensda interface)...
Jonatan,
Sorry to hear that you messed up your KMS enabled part with the MBED fw. I've been working tirelessly to try to eliminate this trouble. If there is anything NXP can do to assist please let us know.
You have a good point. A ROM would be ideal for this application. However, NXP had developed the MCUs prior to the availablity of the KMS library and the MCUs did not include a ROM
