Hi,
I am working with the BF527 Rev 0.2 DSP custom board, 2009R1-RC1 distribution.
In the custom board there are 3 i2c slave devices connected to the i2c port of BF527.
BF527 i2c port as master and devices are acting as saves, now a new device is connected which will act as a master.
new device as master and BF527 as slave. I have 2 questions.
1. will it be possible to have both the master and slave operations simultaneously in the software?
2. do we have the supported apis for slave operation? if so can you please provide the link.
Thank you.

the linux kernel does not support I2C buses as slaves. you'll need to implement your own driver to handle it.

Dear Mike,
The document says the following APIs available.
docs.blackfin.uclinux.org/doku.php?id=i2c
i2c_slave_send and i2c_slave_recv.
I searched in 2009R1-RC1 i could not find them, In which distribution it is available?
Thank you.
