Hello Cypress. I have a cy7c67300 microcontroller. When sending in host->device mode, data is transmitted 0xABCD, and when sending in device->host mode data is received 0xD4C4. With the request code and wValue unchanged. Why doesn't the data match? Help!

P.S. the microcontroller work in standalone mode.ScreenShot_1.pngScreenShot_2.pngScreenShot_3.png

Hi,

Please download ez-host development kit contents in the below link:

https://www.cypress.com/design/SD1025

(Please note that the development kit is now obsolete but kit contents can be installed on your PC from above)

There is documentation available in the below path after installation:

C:\Cypress\USB\OTG-Host\Docs

Hi,

I think you are trying to test loopback operation. In that case a firmware which does the same(loopback operation) should be running in the EZ-Host. As of now, EZ-Host is in BIOS mode - where loopback operation is not supported.
