k60 mqx3.8 ulpi hs support with USB3300

[kyles]

hello,

Using a USB3300 trying to use ulpi hs mode,

MQX 3.8 that supports external ulpi hs?

If that support is apon the MQX need to upgrade?

The purpose is created using the USB3300 NAND flash and SD card as a mass storage device

NAND Flash and SD card both want to look in the window

In that setting, where you want to use an external ulpi?

Different questions

OTG is that the HOST, DEVICE both support?

When connected to a Windows USB3300 alone device name is what?

Hi,

MQX 4.2 supports the K60 devices however MQX 4.2 contains two USB stacks.

New USB Unified stack is designed to replace the legacy USB stack in MQX RTOS, it has an OSA layer so that it can support different operating systems, like MQX RTOS, bare metal or other RTOS (like, FreeRTOS or μCos in KPSDK).

The New USB Unified stack (usb_v2) doesn't support the k60fn120 device. The legacy USB stack supports the K60 devices, however you can port the legacy USB stack to USB_v2, please find more information about the difference between old USB stack in MQX™ RTOS and new USB Unified stack and how to port the USB unified Stack to a new platform, in the docs attached.

Regards

Sol
