Hello, I have attempted to run the BatteryChargerReading demo/tutorial but when I do a logread -f I only see errors (not 100% what I should be seeing but I assume not errors). ![](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/1X/fcb979a548057f64740f88ecb7d0f76cadaf966f.png) From what I understand there is no use of Arduino is this project so I am not sure why I’m getting an arduino bridge error.

@asyal I can’t find a sdef but I assume it’s an adef you are refering too. I have attached it as requested. I should mention I am using the default setup and just running “mkapp -t wp85 batteryReading.adef” on the provided files.

i have tried the program on my unit and dont see the issue. Can you show the mangoh.sdef located in /home/mangoh/mangOH/mangOH folder? It seems like you have a modified mangoh.sdef file that might cause an issue. ---

After doing a repo sync there is a difference between the new and old versions. Here is the new version. Kas [mangoh.sdef](https://mangoh.discourse.group/uploads/short-url/9mjKbvYT7mabXI2JZL8Q9Z2a5y2.sdef) (2.5 KB) I should mention that there is no battery attached to my mangOH board as element14 doesn’t ship one with their kits. ---

After doing a “repo sync” the demo is now working. Thank you for your help. Kas
