Modify DTS File

e14 Contributor

Hi,

I'm about to boot linux with own pl logic and thereby cannot use the default dts file. What parts of the old dts file do i have to delete in order to boot linux?

TY for any hints,

Gerd

    That depends, the names in the dts-file are very descriptive so it is rather easy to figure out which components that should be left. All hard peripherals are listed (first?) but with their addresses in the the 0xE000_0000-area and above. Your custom peripherals are in the 0x4000_0000 to 0xDFFF_FFFF memory area.

    So if you have the standard config in the hard peripherals, leave everything except in the 0x4000_0000 <-> 0xDFFF_FFF area.
