I have a Nucloe-H743ZI and Nucloe-H743Z2, I was wondering if you have any sample code or any tutorial for USB ( FS and HS) and Ethernet (Echo Server for example)?

With the USB sample code that I have, I get the following error:

"device descriptor request failed"

The heap size = 0x1000, so I do not think that is the issue and I do not see any bug in the code.

Hi HElah.2,

Please refer to STM32CubeH7.

For USB projects, please refer to this directory: \Projects\$Board_name$\Applications\USB_Host/Device
For Ethernet and LwIP projects, please refer to: \Projects\$Board_name$\Applications\LwIP
You can also refer to this FAQ and this OLT

Best Regards,

Ons.
