When I use the I2C external touch screen of am3352, when the touch screen touches multiple points, the I2C bus will die, and it will also cause the crash of am3352 and system reset.
What causes the CPU reset problem.
Look forward to your reply，Thanks.
The following is the error message，When the problem occurs, other devices on the I2C bus cannot communicate normally.
