}

This is the code that i have for transferring from Computer to zedboard and again from FPGA to zedboard. I wrote a single python script for transferring data.

 

import serial
import os
## python -m serial.tools.list_ports -- listing ports
ser = serial.Serial('COM11',115200)
print(ser.is_open)

file_size = os.path.getsize("<file_path>")
print(file_size)
with open('<file_path>', 'rb') as file:
    while True:
        data = file.read(128)  # Read 128 bytes at a time
        #print(data)
        if not data:
            break
        ser.write(data)
print("Broke from the loop")
print("finished transferring")

print(ser.read())
response = ser.read(file_size)
print(response)

ser.close()

The files are transferring to the zedboard but not the other way around. What is my mistake here? 

Earlier working code was a simple file check

        while (Status < NUM_OF_BYTE) {
            Status += XUartPs_Recv(&Uart_PS_1, BufferPtr_rx, 1);
            if(BufferPtr_rx[0] != '\n'){
                            check[Status] = BufferPtr_rx[0];
            }
            //Status++;//Status += XUartPs_Recv(&Uart_PS_1, BufferPtr_rx, (NUM_OF_BYTE - Status));
        }
        //XUartPs_Send(&Uart_PS_1, check, (NUM_OF_BYTE));
        for(int i =0;i<NUM_OF_BYTE;i++)
        {
            xil_printf("check : %c",check[i]);
        }

        if(memcmp(check,test,NUM_OF_BYTE) == 0 ){
            xil_printf("Success!!");
            XUartPs_Send(&Uart_PS_1, hacked_string, 7);
                }
        else
        {
            printf("What?!");
        }

    }
    cleanup_platform();
    return 0;
}

This code was working with the exact output but not the previous code. I am sry if this too lengthy
