Use a few dtbo file in overlay

[M@riusz 0]

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 @M@riusz, 

 

please copy the dtb files from https://www.asuswebstorage.com/navigate/a/#/s/00E9A5E1D5AC45FFBE5EBC6738DFEFAB4 to /boot/overlay, and modify /boot/config.txt to enable spi2 accordingly.  

overlay=mcp251x-can0-tinker1

save the /boot/config.txt and then reboot tinker board r2.0

confirm that can0 can be recognized with command:

ifconfig can0

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.

hello @M@riusz, 

are you connecting it to i2c1?

please space it instead of using a comma:

overlay=ds1307-overlay mcp2515-can0
