I have my unibone working and I have worked through the memory checks on my memory card and all was ok.
I have been logging on using SSH. But next I wanted to emulate a cpu using the memory card and so tried to logon via the serial console. After waiting the usual time I get nothing but garbage on the screen.
I have tried using serial tools on my MacBook, using PuTTy on Windows and using a VT132. The result is always the same.
I tried logging on with no other card on the backplane with no change.
I tried varying the stop bits, parity and baud rate - but nothing made any difference.
I have checked out the connections to the Maxim3232 and the voltages are correct and the connections to the BBB from the Max3232 are also ok. I cannot see from the schematics that there is anything else in the circuit.
I have tried different cables but again no difference
I have a serial cable connected to UART1 with a nul modem connector.
I have attached photos of the output on the MacBook and on the VT132.
How do others have this setup - do I have to do this via Linux. I have linux but couldn't get minicom to respond.
Can anyone throw any light on this?
thanks for any help
