Hello,
I was wondering about booting U-Boot on a brand new AM335x board without any bootloader loaded in flash or anything. We're talking blank from scratch board (assume we're just saying it has the processor and external RAM).
I was wondering particularly about USB booting via TFTP. If I recall correctly booting through USB is basically like a virtual ethernet interface which can use TFTP. So I was wondering, is it possible to load the X-Loader/SPL via USB/TFTP which will set up the external RAM and such and then also using USB/TFTP then load the U-boot image into the external RAM and run it.
So instead of needing to insert a SD card with the images on it, just load U-Boot straight from USB/TFTP. Is this possible? I'd seen a lot of guides about using USB/TFTP but didn't really know if it could be used like this since in order to get U-boot loaded you're using two separate bootloader images.
