about netbooting on armv6

Bernd,

Don’t know if the following is going to help. I am netbooting an rpi-3 using loader.efi

What I did was the following.

1. I booted of an 12-RELEASE SD-Image.
2. Mounted a NFS file-system that became my root file-system
3. Copied everything from / over to that file-system
4. Added to dhcp.conf
host raspberrypi {
  hardware ethernet b8:27:eb:2b:37:e1;
  fixed-address 192.168.1.87;
  option host-name "raspberrypi";
  next-server 192.168.1.1;
  option tftp-server-name "192.168.1.1";
  option root-path "192.168.1.1:/zdata/rpiboot/armbsd";
  filename "armbsd/loader.efi";
}

5. Under tftpbooot I copied bootcode.bin
6. With tcpdump I traced which directories it was going to open files on.
In my case it was bd2b37e1 (which is derived from mac)
7. Created /tftpboot/armbsd and a symbolic link from armbsd to bd2b37e1
The contents of /tftpboot/armbsd is (from the SD card) Not everything is used and the pxelinux.cfg is not needed
ls -R /tftpboot/armbsd/
armstub8.bin		dtb			fixup_db.dat		overlays		start_cd.elf		u-boot.bin
bcm2710-rpi-3-b.dtb	fixup.dat		fixup_x.dat		pxelinux.cfg		start_db.elf
config.txt		fixup_cd.dat		loader.efi		start.elf		start_x.elf

/tftpboot/armbsd/dtb:
allwinner	overlays

/tftpboot/armbsd/dtb/allwinner:
sun50i-a64-nanopi-a64.dtb	sun50i-a64-pine64-plus.dtb	sun50i-a64-sopine-baseboard.dtb
sun50i-a64-olinuxino.dtb	sun50i-a64-pine64.dtb		sun50i-h5-orangepi-pc2.dtb

/tftpboot/armbsd/dtb/overlays:
sun50i-a64-sid.dtbo	sun50i-a64-ths.dtbo	sun50i-a64-timer.dtbo

/tftpboot/armbsd/overlays:
mmc.dtbo		pi3-disable-bt.dtbo	pwm.dtbo

/tftpboot/armbsd/pxelinux.cfg:
01-b8-27-eb-2b-37-e1

8. Changed fstab on the NFS share and added boot.nfsroot.options=“nolockd” to loader.conf
