Product Number: ADUC841 - cannot connect to target device
Software Version: WSD 7.0.5
Trying to connect to ADUC841 using UART serial port and WSD cannot communicate with the target device:
'Status: Failed to connect to the ADuC8xx after 2 attempts'.
Baud Rate and Port show up as ok. PSEN is pulled low via a 1K resistor on power cycle.
I am using a USB2.0 to RS232 cable. Strange.
What is meant by the following (from ADUC841 datasheet): 'Once in serial download mode, the user can download code to the full 62 kBytes of Flash/EE program memory while the device is in-circuit in its target application hardware.'
Help would be greatly appreciated.
