sc16is750 with Banana Pi M2 Zero

Recommended Posts

I have attached sc16is740 to the I2C port of BPI. sc16is740 is a device that lets me work with i2c like a uart. The device is detected with the comand:

sudo i2cdetect -y 0

nº48

00: – -- – -- – -- – -- – -- – -- –

10: – -- – -- – -- – -- – -- – -- – -- – --

20: – -- – -- – -- – -- – -- – -- – -- – --

30: – -- – -- – -- – -- – -- – -- – -- – --

40: 40 – -- – -- – -- – 48 – -- – -- – -- –

50: – -- – -- – -- – -- – -- – -- – -- – --

60: – -- – -- – -- – -- – -- – -- – -- – --

70: 70 – -- – -- – -- –

Then I have load the driver with: sudo  modprobe sc16is7xx 0x48

Using:

sudo  modprobe sc16is7xx 

I see the module sc16is7xx loaded using:

sudo lsmod

However, the system does not created a new interface like ttySC0 and I do not know how to tell the driver which IRQ Pin should use.

I have tested also:

sudo modprobe i2c:sc16is740  int_pin=4 addr=0x48

Then, I have added the module to: /etc/modules-load.d/module_name.conf
 

I am missing some steps.

Could someone help to load this driver?


 

PSD: I have try also to load this driver in an Radxa Zero. Same result

Thanks
