Enabling 5G Module on Layerscape Platforms

[yuantian]

Want to use 5G module on Layerscape platform? The attached Application Notes will help you to do this.

This AN will help you:

1.  Set the 5G environment on Layerscape platforms

2.  Connect 5G modules to Layerscape platforms.

3.  Install the software required for 5G modules and 5G test on
OK1028A-C v1.1 and OK1046A-C2 v1.1 boards. The boards come
from a third-part company, Forlinx, and they can be bought at

https://www.forlinx.com/

4.  The test process and the reference result of the test

The patches for 5G modules are based on linux kernel v5.4.49. You may change a little bit if you are not using this kernel.

Have fun with 5G modules.

We developed LS1046 based custom card. After assembly we found short in one of NXP LS1046 chip power voltage 1.2V.

Please tell us , what is minimum resistance vale measured between 1.2Voltage and GND for NXP device LS1046.

Could you please answer my query ?

[yuantian]

There’re two power rails with 1.2V input, like G1VDD for DDR4 I/O and TVDD for GPIO2, on LS1046A.

Which 1.2V are you referring to?

Hi ,

We are planning to develop custom board using  Layerscape platform LS1046a for 5G CPE application.

we have selected Telit 5G FN980 modem.

Please let us will NXP LS1046 will support & tested with  FN980.

Hi Suma,

No, FN980 was not tested on Layerscape platform.

That doesn't mean it was not supported.

You need to port the 5G driver and update the USB/PCIe driver a little bit.

Good luck,

Andy

Thanks Yuantian,
It means we need to get 5G driver details from Telit and the same we need to update it on NXP..
and through USB 2.0/3.0 we need to configure and acces Telit modem.
Please suggest further, as we are designing the custom board with LS1046A & FN980 .

Thanks
suma

You need to contact Telit support first.
They should know how to enable this module on linux thus on LS1046A.
Normally the steps are:
1. Get the driver for the module and integrate it to linux.
2. update drivers/usb/serial/option.c file to add the information of moderm.
3. update other driver needed by Telit moderm.
4. test.
