Hi All,

We want to use the BBB as i2c slave and arduino as i2c master to exchange some periodic data to BBB. We were searching option to access the BBB as i2c slave but could not find anything conclusive.

Is that possible to access BBB as i2c slave? Anyone tried it. If yes, Please share steps to configure it.

Regards,

Riyaz

The TRM (SPRUH73P, page 4588 - 4590) seems to imply the chip is capable
of slave mode, but it may be that the kernel drivers don't support it.
Reference TRM page 4596/section 21.3.15

The alternative might be to use a PRU and bit-bang the I2C protocol.
