pvt board problems #17

Open arblake opened 3 years ago

arblake commented 3 years ago

If I upload Rob's eforth it reports that ttyACM0 is available. If I open a terminal program like gtkterm, the port, ttyACM0 dissappears. If the terminal programming is running before I upload the eforth . If Rob does the same with the hacker board he has no difficulties. He can remove the board and replace and still all works, whereas I must reload the eforth. Any suggestions?

eforth looks like it's overclocking the FPGA, and so it is susceptible to device variations. This means it may not work on your board.
