Problems with CY7C65213 when reading UART

[Anonymous]

Hello Everybody,

   

I hope it's the right forum branch for posting.

   

I'm working with CYUSBS232 USB-UART LP Reference Design Kit which has CY7C65213 part installed . I've made a program in MS VIsual C++ 2008 that succesfully reads device parameters, opens device, operates GPIO pins and sends the data through UART via CyUartWrite(). However, when I want to read the data from UART and thus I call CyUartRead() API's function a breakpoint/exception is generated saying something about heap corruption (can't cite the exact message). Intrestingly, this doesn't happen if there's some data received in the input buffer - CyUartRead() returns CY_SUCCESS with correct data reading. I believe this is not a normal behaviour of CyUartRead(): in case of no data received it should simply CY_ERROR_IO_TIMEOUT saying timout has been reached.

   

Does anyone had similar problem? Any suggestions?

   

Thanks in advance

 Hello Alexunder,

   

We have seen similar issue and this is issue with our cyusbserial library. I will check and provide you modified binaries which has fix. However, we will update our library including this fix in our next release.

       

Thanks,
