Zephyr USB support for LPC54114 uC

mme — Fri, 12 May 2023 10:00:10 GMT

Hello

is the USB controller in LPC54114 supported with Zephyr? As far as I could investigate, the USB is based on LpcIP3511 which indeed is supported but I could not get it working or find matching examples.

Thanks for feedback.

Hello @mme

Yes, it support: https://docs.zephyrproject.org/latest/boards/arm/lpcxpresso54114/doc/index.html

There is a training about Zephyr with NXP, you can have a look at:

Hi @Alice_Yang

Thank you for the link. USB is not stated on the supported features list, which is why I placed this question first hand. However, the USB Core IP3511 has Zephyr driver support, so what is missing, is a DTS/DTSI for the SOC supporting a USB Interface. Anything you can do to make this supported?

Hello @mme

1) About Zephyr detail issue, you can ask at Zephyr community, NXP’s support team actively monitors the Zephyr community to support customers with questions specific to NXP’s platforms.

2) Can you access this thread:

If yes, also can ask Zephyr question here.

Hello @Alice_Yang

Since you say that LPC54114 is supported, can you kindly provide a complete Devicetree with USB and even a basic example? Documentation is not available and you always refer to your examples, so getting one would be essential!

Thanks.

Hello @mme

I confirmed with our SE team, the USB Devicetree doesn't support lpc54114.

If you to know additional information about Zephyr, you can create a new thread on community , and mentioned

Derek Snell <derek.snell@nxp.com> for help.
