S32K144 Q100 Eval board support in zephyr

[adarshvs]

I have successfully added support for the S32K144_Q100_eval board in Zephyr. Most of the files were ported from the S32K146 (UCANSIC board). However, I couldn’t find the FTFC drivers for the mentioned board, so i ported the FTFC driver code from the S32Design Studio RTM SDK.

Currently, I am planning to add support for the S32K144_Q100_eval in Zephyr. However, the FTFC driver files contain the following header from NXP:

* Copyright 2016-2020 NXP

* bound by the applicable license terms, then you may not retain, install,

Are there any modifications required for uploading these files to Zephyr?

Hi @adarshvs ,

Zephyr RTOS already has support for FTFx flash controllers based on MCUX-SDK. The existing driver could be extended to support the FTFC version for S32K1xx devices, as the differences with other controller versions should be minor.

Best regards,
Manuel

Hi @adarshvs 

the flash driver in SDK does not use OSIF (this is used mainly in drivers for communication peripherals), so I don't think that modification are required.

Hi Lukas,

The driver code is already working.

My query is regarding the legal issues of  reusing the NXP sdk files on zephyr.

Can i use those files and push to zephyr code base.

Ok, got it. I discussed this with our license advisor and his question is  - what will be the license on the output?

Currently we are planning to push the file as same as in the SDK.

but zephyr uses apache 2, so should we keep the file headers as the same or need to remove it.

File header is mentioned above please check.
