I implemented an algorithm into fpga board. I wrote the Matrix data to FPGA board from Matlab and the result came back. I was using a loop to execute the operation many times. It can operate normally for some times, but in the end it stopped with the error in the line : fwrite(sx,datafile,'int8'); and the error messege showed : serial.fwrite A timeout occurred during the write operation. How could it happen? How could it execute some trials but happen time out error at some time?
