Re: USB flashing/Li-po boards Message #7 Posted by patryk on 8 Sept 2013, 12:31 p.m., in response to message #6 by Marcus von Cube, Germany
Using an FTDI breakout board, I was able to reflash a 34S with a broken LCD and no other issues, but experienced some strange issues. This 34S had the crystal installed and had the calc_xtal_full firmware. I put it in bootloader mode and was able to flash the calc_full (not calc_xtal_full) firmware right away. After the flashing, it would randomly turn off after I turned it on, sometimes right away, sometimes after tens of minutes. So, I flashed calc_full again, again without any issues. The calculator was still randomly turning off, so I put it into bootloader mode again (now the third time) and tried to flash calc_xtal_full, but I'm not able to. The calculator isn't giving any response to the programming attempts. Any idea what the issue could be?
