I am hoping that you can help me. I am trying to program a Futurlec controller board that is fitted with an ADuC832. I am using WSD7.05 for programming the code. This is very intermittent, but when it appears it locks solid.
However, when I try and program, the baud rate changes from 9600 to 115200 and of course the connection drops. I have exactly the same problem on other boards in production. I have detailed the configuration and the error below.
I am connecting using RS485. Computer is Windows XP SP3. I am using a USB <> RS485 converter.
Note baud rate is correct at 9600
Download – the code erasure works OK at 9600. When this is completed, the baud rate changes.
Note – Stage Changing to fast baudrate
It then errors – after erasing the code !
Note the comms is now 115200 baud and the Crystal frequency has changed.
