2nd I2C Bus Occasionally Fails
Have been running Ubilinux and MRAA 1.9.0 and using both I2C ports to talk to 2 seperate devices (1 per I2C bus). However, occasionally the second I2C (on pins 27/28) fails on typically first read operation - here's the error in the journal file
Jul 12 19:08:54 ubilinux4 libmraa: i2c_init: Selected bus 1
Jul 12 19:08:54 ubilinux4 libmraa: i2c0: write_byte: Access error: Remote I/O error
Normal operation is something like this
Jul 12 19:49:27 ubilinux4 libmraa: Adding i2c bus found on i2c-1 on adapter .
Jul 12 19:49:27 ubilinux4 libmraa: Adding i2c bus found on i2c-0 on adapter .
Jul 12 19:49:27 ubilinux4 libmraa: i2c_init: Selected bus 0
Jul 12 19:49:27 ubilinux4 libmraa: i2c_init: Selected bus 1
Need a restart to get this to work. Anyone else experience this issue or has used both buses with no issues? Anything else to look for to troubleshoot?
