Role of device tree in boot process #258

Closed phanbagiabao2001 closed 2 weeks ago

phanbagiabao2001 commented 1 month ago

I find that in file config.txt, there are 2 lines about the address of device tree:

device_tree_address=0x1f0000
device_tree_end=0x200000

Can you explain me what do they do here? We can not boot with device tree so for which the device tree (dtb) is used?
