Driver SC16IS7xx (UART)
« on: May 28, 2018, 01:06:01 AM »
Hello,

I would like to use an self-designed extension board with piCore 9.0.3. On my board I have two SC16IS752 (Dual UART with I²C-bus/SPI interface) configured for use with I²C. On Raspbian I found a dedicated driver for this chip an I could already test my board so I know it is working well. But I can't find any driver for piCore. I also don't know how I could transfer the driver from Raspbian to piCore. Would this be possible?

Thank you in advance for your support!

Regards
Bernd

Here you have some example of how to make your own TCZ module to load linux module.

Thanks!

At the moment it is already fully working without a TCZ module. But I have a problem how to create a dtbo-overlay on PiCore. I solved this problem for me by taking my previously made dtbo-overlays from Raspbian. On PiCore I'm missing the file "dtc" (device tree compiler?) to generate these dtbo-overlays out of my config files. Can you tell me where I can find/download this and how to install?
