i2c slave support für i.mx6

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am currently working with a I.mx6 quad-core-processor on Linux 3.19.
I would like to implement the "I2C slave support", by Wolfram Sang, In
this processor.

For this purpose, I would have some comprehension questions.

Do I understand it right, I can set the Master in slave mode and the
new slave get his own i2c-adresse?
Say that, I can connect a Master from the outside, without this
leading to problems?
If the master switch to slave, then stops SCL? Or how does it work?

Is the EEPROM simulator only available if I rewrote "i2c-IMX" drivers
to the slave support?

Does anyone know if anyone is working on this driver?

In the "i.MX 6Dual/6Quad Applications Processor Reference Manual",
from freescale, on the page 1895 the "Hardware"-Slave Mode will be
described.

Would it theoretically be enough to write 0x80 in the "I2Cx_I2CR"
register to set MSTA Bit to
slave mode. "Changing MSTA from 1 to 0 generates a Stop and selects Slave mode."
Or then disturbs the old driver?

best regards
