XferData | Cypress Semiconductor
I am using 32 bit slave fifo interface. I send from FPGA to FX3 64 Words (total 256 bytes) with a zero lenght package at the end.
With C# I read using XferData with len = 1024. The function returns with len set to 256 which I expect.
However if I read with C++ XferData with len = 1024, I get the error 997.
Why is it different between C# and C++?
