I seem to have an issue where the the I2C buses 1-4 keep getting lost. That is the I2C multiplexer driver is getting lost/corrupted/uninstalled (basically not sure but not there). I can verify this by doing “i2cdetect -y -r 0” and I see a 0x71 instead of UU in that location, also “i2cdetect -l” only brings up bus 0.
An easy fix for this as pointed out by @dfrey is to go to the mangoh folder do a “make red_wp58” and the a “update mangOH_Red.wp85.update 192.168.2.2”.
This is a good work around that allows you to keep working. The answer I’m really looking for is why does this keep happening and how can I prevent this. If I’m running some application where I can’t get to the unit to reinstall anything (weather balloon at 37000 feet) I need to know that my application is reliable and the system will keep reporting the data needed.
