Created attachment 210392 [details] sysutils u-boot-osd-customboard patchset This port is a starting point for embedded custom boards based on OSD3358/AM335x with blank EEPROM. You have to adjust the device tree for your unique hardware. * Implementation described here https://octavosystems.com/app_notes/osd335x-eeprom-during-boot/ * And Robert C Nelson patchset 2019.07 https://github.com/RobertCNelson/Bootloader-Builder/tree/master/patches
I'm not sure that adding code from a vendor u-boot as patches is a good idea. This will likely be a problem when upgrading to newer u-boot and that is not something that I want to deal with.
(In reply to Emmanuel Vadot from comment #1) Of course it will be some work when upgrading u-boot. Perhaps a more approachable path is to suggest upstream uboot to introduce a blank eeprom option for am335x.
