I have a standalone app that I had working on an earlier version of u-boot, but I can’t seem to get it working on anything recent. Indeed, I can’t even get the included hello_world example working (though U-boot itself works fine). I load hello_world.bin at address 0x80300000, then go 0x80300000, and it crashes instantly:

Has anyone seen this working on the BBB recently, or did the U-boot guys break something?
