Hi
I´m trying to send the Boot 2 to my calculator with Hyperterminal but once I get into the menu to flash it with , I get the text saying "Begin XMODEM file transfer" which is fine but then a bunch of strange symbols ("") start to happear and if I try to send it to the calculator it just gives connection failure.
Here is a screenshot:
What should I do now?
Note:If I don´t connect USB TTL to the PC just to the calculator. It gives me steady red and steady green
