I’ve followed the getting started guide, I followed the guide created the mcs file and programmed the FPGA with Vivado successfully. No matter what I try, I can not get the Sifive logo in the default program to print to the terminal, it is always blank. I’ve tried Linux screen command, double checked the baud rate 115200, no parity, 1 stop bit, cs8, hardware flow control off. I’ve also tried the same with minicom. Nothing will show in the terminal. When I open the serial port and i type buttons, I can see a LED beside the micro-b usb connector on the board blink whenever I press a key on the keyboard. Hitting reset should print the sifive logo out in the terminal, but I never get it. Help please!
Note: The only thing that I had to change from getting started guide is the part with programming with vivado. It says
[Labtools 27-3291] Flash Programming Unsuccessful. Part selected mt25ql128, but part s25fl128sxxxxxx0 detected.
I change the part to the detected one and it programs fine, but no serial output.
