MCP2515 not working on raspberry pi 4 with AGL

Description

Hi,

I am unable to load the Mcp2515 driver on AGL. I am using Raspberry pi 4 with AGL for a POC. I have tried using the device tree overlay method and added the following lines in the config file:

dtparam=spi=on
dtoverlay=mcp2515-can0, oscillator=8000000, interrupt=25

dtoverlay=spi0-hw-cs

The Raspberry pi keeps on crashing when I make this change.

Can someone please help me with this? I have been stuck on this for quite some time now. Is there any other way by which the mcp2515 driver can be loaded on AGL?

Does this still apply on master or on plain meta-raspberrypi ?

dtparam=spi=on
dtoverlay=mcp2515-can0, oscillator=8000000, interrupt=25
dtoverlay=spi0-hw-cs

Here is the error log we got.
