Firmware update just hangs
27.09.2016, 23:02
(Sorry for the English entry - feel free for responses in German!)
I was having problems with the alarm interrupt. It was not firing and thought to upgrade the firmware. I have downloaded and unpacked the firmware-Update V1.3.
In my case, I am not using Arduino and have already removed the module from the shield. So my only option is to use the UM2101.
When I run the update.bat, I get asked for the COM port, in my case 4 and press enter. Another window opens for the update.exe and nothing else. I don't get any percentage progress. Just a blank window. Connecting a Scope, I can see no activity at all on the Tx and Rx lines.
I did connect PUTTY to the UM2102 and could see that it seems to be working fine (i.e. bridged the Rx and Tx).
One thing I find puzzling is in the "Firmware-Update des RTC-DCF.pdf", It says to connect Tx to Tx and Rx to Rx between the DCF77 and the UM2102. I am wondering if that is correct? Normally Tx is connected to Rx and Rx is connected to Tx, I would have thought - I did swap these over and there is still no response.
Any ideas would be greatly appreciated.
