I have been trying to interface a Panasonic A6 servo via EtherCAT to a SanCloud BeagleBone Industrial board. Whilst Installing the runtime via SSH in CoDeSys, I ran across this error. The program compiles and runs on the BeagleBoard and have not run into errors so far. I would like to know the significance of the error message.
Someone else seems to have had the same message but I'm not sure if their issue had anything to do with that.
It looks like it can't access a file nvmem, nonvolatile flash memory. It looks like it might be for a device at24-0. Googling that it is a driver at24.c for an Atmel24c Eeprom which is also capable of handling most i2c eeproms.
Here's some links that might be helpful for you.
I have been developing my application with CoDeSys runtime on the BBB for more than two weeks now without any issues. I still get the same warning but the code seems to compile and run fine.
