I found this topic where you mentioned switching to 2020.04 device-tree model.
I have a custom board based upon BBB. My board has two LAN8710 ethernet PHYs wired RMII. I am using u-boot 2019.04 with your patches, kernel 4.19.106-bone49. I use BeagleBoard-DeviceTrees-4.19.x-ti to build my custom DT.dtb file. I have created a custom device tree based upon am335x. When the kernel boots it loads my custom DT.dtb.
Does the ‘old board file method’ mean that u-boot uses the u-boot-v2019.04/board/ti/am335x/board.c file?
Are device-tree method, driver model and CONFIG_DM_ETH all the same thing?
Back in August 2020, u-boot was at version v2020.04. I noticed today that latest u-boot is v2021.01.
I understand that u-boot is closely related to Linux.
If I change to v2020.04 or v2021.01…
What kernel version do I need?
What version of BB-DT builder do I need?
Will u-boot v2020.04 and/or v2020.01 use the same DT.dtb file for configuration?
I’m sorry for the excessive number of questions.
