I2C3 hangs after several write

carlovalgocela — Mon, 05 Oct 2015 07:50:59 GMT

Good Day!

I have added I2C3 in the kernel Linux-3.0.15-ts-armv71 with I2C3 clock set to 100Khz.

I'm having some issues with my A5 application were sending of I2C data results to SDA pin stuck to LOW.

This usually happens when a NACK is received. The only way to recover is to power reset the board.

Is there a way to send a stop command when a NACK is received so that we can restart sending?

Hello Carlo,

Are you able to, or have you already, provided your application in the Timesys Support queue for this issue? Are you able to do so, so our engineers can reproduce and investigate the behavior?

Thank you,
