SDK builder vs Github vs MCUXpresso.. many options to do the same thing

[dav1]

Trying to understand what NXP considers to be the "right way" to get the absolute latest SDK files, i.e. HALs and drivers like usb stacks.

As far as I know we have

1. https://mcuxpresso.nxp.com/en/welcome
2. https://github.com/nxp-mcuxpresso/mcux-sdk
3. Direct download SDK files in MCUXpresso IDE

It also seems that there are different versions of files in the IDE vs the ones you get via the online sdk-builder. What is considered the source-of-truth?

Related question:

- where is the official documentation for lets say the USB stack for LPC5x ?

Hi,

Thank you so much for your interest in our products and for using our community.

There is no a "right way" to get SDK files.

Through the IDE you will get the latest full version of the SDK (depending of the IDE version). On the other hand, github is a new way that is gaining popularity. Regarding MCUXpresso SDK Builder, it is a little more flexible, you can choose different versions, the middlewares that you want to include or not include, as well as choose the Host OS and Toolchain/IDE.

Regarding the USB stacks documentation for LPC5x you can find in the SDK, for example for the LPC55S69-EVK:

Hope it helps you.

Have a nice day!
