Use a few dtbo file in overlay

hello @tooz

Thank you very much for your help, it actually works with this configuration 😀

I can not believe it 😉

[Use a few dtbo file in overlay]

hello @tooz

But the CAN support works without any problems with mcp2515-can0.dts -> Link

What about RTC ds1307? 

How to set RTC and CAN in config.txt

Is dts set 8mhz or 12mhz? Please share the dtbo file.

 

[Use a few dtbo file in overlay]

Hello,

I'm having trouble using several dtbo files in overlay in /boot/config.txt

I try several config, but not working:

#1 - not working
overlay="ds1307-overlay","mcp2515-can0"

#2 - not working
overlay=<ds1307-overlay> <mcp2515-can0>
  
#3 - not working
overlay=ds1307-overlay
overlay=mcp2515-can0

#4 - not working
overlay=ds1307-overlay, mcp2515-can0

Single use of dtbo files in overlay works fine.

Please help.

Hello, 

Did you manage to prepare the os to communicate with mcp2515?

I tried to configure the os for mcp2515 on kernel version 4.4.194 but the system does not boot after uploading mcp2515-can0.dtbo to /boot/overlays/
