Thanks for this workaround. I will use this. I will later send a patch they store the device tree address on raspberry into a variable. So that user can load this, if he need it. The question is now, would you allow to load a device tree with a memory address on oftree utility? And if yes, where is the best place to add this function. greets Pascal 2018-06-07 9:20 GMT+02:00 Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>: > On Wed, Jun 06, 2018 at 03:16:02PM +0000, Pascal Vizeli wrote: >> DON'T MERGE: this is only a concept patch. >> >> On some device, barebox is the second bootloader.
