Hi,
We are still trying to connect LPC4357 based custom board to Windows host using USB. Again we are using USB0 on the LPC4357 for this connection. After some digging, we got the following link where we could download WInUSB driver for LPC4357.
https://community.nxp.com/docs/DOC-339335
Initially we tried on the Windows 10 machine and when that machine failed to recognize the USB connection to LPC4357 board we used a Windows 7 host and downloaded the windows USB driver from the above link. Even after updating the driver we get the message “Unknown device” unlike the link mentions “ LPC device”
We get the following messages when we connect the LPC4357 custom board using USB to Windows 7 host.
Device Driver Software was not successfully installed
Please consult with your device manufacturer for assistance getting this device installed
Unknown Device XFailed
Is there some other Windows driver we need? We would like to use Windows 10 host. Do you have driver for Windows 10?
Thanks
Can you be sure that the USB0 port works fine on your custum board? If the quality of the connection between the MCU and the PC is not sufficient, then the driver can't be loaded correctly by Windows.
I just tested it on my Win7 PC with a KEIL MDK4357 board in USB0 boot mode and the device gets correctly identified as "LPC device".
