USB Low-Full-High Speed Peripherals

New Contributor

Hi, I have tried to execute the SPI VCP/CDC but it stops at "CySpiReadWrite_VCP" with a time-out error.

There is already an entry in the community, which seems to deal with the same/similar issue (CY7C65211A SPI access ).

What have I done:

1. I am using the CYUSBS236 USB DVK BOARD

2. I replaced the CY7C65215 with the CY7C64215A

3. I have checked the functionality using the "TestUtility" -> I2C/SPI -> OK

4. I have started with the I2C example delivered with the driver SDK --> OK

5. I tried to use the SPI example --> FAIL

Any advice on what could be done to get at least the example working?

thx

Hello,

I have tested the functionality without any issues.

Can you please let me know if you have modified the application?

Also, please make sure that the below conditions are met:

1. SCB is configured to SPI CDC Master and the COM port is enumerated in the device manager.

2. COM port is bound to USB-Serial Port Driver and not USB-Serial Device Driver

3. Proper jumper settings are made on the DVK,  as per Figure 3-36. SCB SPI Jumpers in CYUSBS236 Kit guide

4. The correct COM port number is passed as input to the application.

Thanks,
