I've found that

f3866909e350 ("distro_bootcmd: call EFI bootmgr even without having /EFI/boot")

breaks running EFI application from USB device on BeagleBone Black
(am335x) device.

With this patch I see the following:

Booting /efi\boot\bootarm.efi

while without the patch, GRUB works as usual.
Could you please help me to figure out what is going wrong here?
