fsl_fro_calib source code

Due to errata USB.1 in ES_LPC5411x, the workaround in TN00031 is required to implement crystal-less USB across multiple USB hubs. I am looking into supporting multiple serial ports from a single device. However, the sample in the SDK (usb_device_composite_cdc_vcom_cdc_vcom) doesn't seem to reference the fsl_fro_calib or TN00031 errata anywhere? Is there source code available for the fsl_fro_calib library in TN00031 so I can port it? If not, how can I have multiple serial ports enumerate from a LPC5411x across multiple hubs?

Please let me know SDK and IDE version. I will check.

Thanks,

I'm using MCUXpresso SDK 2.9, with my own editor (vs code) and toolchain
