5inch LCD Display W500 - touch error

Moderators: chensy, FATechsupport

When we touch an LCD, it will stop with the following message on Smart4418. (4.4.172-s5p4418 version is in use.)

nexell-i2c c00a6000.i2c: trans[ 0: 3]
nexell-i2c c00a6000.i2c: Fail, arbit i2c.2 addr [0x28] data[0x28],
nexell-i2c c00a6000.i2c: trans[ 0: 3]
nexell-i2c c00a6000.i2c: Fail, arbit i2c.2 addr [0x28] data[0x28],
nexell-i2c c00a6000.i2c: trans[ 0: 3]

Is there a solution?

Do you have any other device on the I2C bus that is using the same address?

Are you able to check the I2C to see if there is clock and data appearing?
