Hello. There seems to be a bug in getting the ID in i2c_add_numbered_adapter() It uses dev.parent instead of dev, for example: of_alias_get_id(adapter->dev.of_node, "i2c"); And with this everything works as expected. чт, 12 дек. 2024 г. в 12:03, Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>: > > Hi Alexander, > > On Wed, Dec 11, 2024 at 09:14:32AM +0300, Alexander Shiyan wrote: > > Hello. > > > > After updating barebox to version 2024.12.0, an error message appeared > > when loading > > the RK3568 board.
