USB Low-Full-High Speed Peripherals

[SeungM_41]

Hello

My customer is using CY7C65211A as USB-SPI master on Linux.

They have some question like the following.

When isCypressDevice() is called thru printListOfDevices(), this seem to have a memory leak.

Code	while(1) {         rStatus = CyOpen(0, 0, &handle);         if (rStatus == CY_SUCCESS)             CyClose (handle);         else             printf("CyOpen Fail(%d)\n", rStatus);     }
Log message	[ERROR]CY:Kernel driver active on the interface number 0 CyOpen Fail(4)

Deription :

if System board is connected with good device (as Cypress CY7C65211A) and called CyOpen(),

System board seems to be good working with CyClose() as rStatus == CY_SUCCESS.

but, if System board is called CyOpen() (as No device), it seems to have a memory leak.

if CY_ERROR_DRIVER_OPEN_FAILED as return value thru CyOpen() is repeated infinitely,
They would like to know if there can be happened a memory leak as symptom. also, if yes, could you please let me know method to solve memory leak?

Regards,
Jake

Hello Jake,

Can you please ask the customer to re-build the library by replacing the  cyusb.c present in the <installation path>/linux/library folder with the one attached to this response and use the newly built library.

Let me know if they still face the issue.

Thanks,

Yatheesh
