Can't open com port

Postby dposea » Sun Feb 17, 2019 6:35 pm

I need yo update the firmware because any button pressed turns on holld. EEPROM forced reset did not fix that. Should I attempt a flash via the programming header using an arduino nano? I have several on hand. I had many problems getting this to work but the biggest problem was a bad crystal, You need to update the instructions with a test of U4, suggesting some way to verify the crystal is working. Also my switch board never worked, and BOB4 soon failed also. I was able to bypass both and it worked for a few minutes before it froze. After that all buttons place or remove the hold.

I got the com port to open b installing the virtual box guest addition software in my windows VM. I get this:

Start download
$ Send reset command: [7E ]
> Start connect
$ <1> Send connect key: 64
$ <2> Send connect key: 64
$ <3> Send connect key: 64
: 0C 82 .‚
: 4C 0E L.
: 4C L
$ <4> Send connect key: 64
$ <5> Send connect key: 64
$ <6> Send connect key: 64
$ <7> Send connect key: 64
$ <8> Send connect key: 64


using baud rate 9600, 8, 1, N, N

I get the smae 5 bytes of data after hitting reset, so it seems data is coming from the 068.
