(Excuse my previous post was sent draft/incomplete)
Hi, I'm trying to do same thing: "boot orange pi zero from SPI FLASH+USB pendrive without SD card".
I think I followed all steps mention above but boot sequence is failing leading to a reset loop.
This is all I have done:
Soldered W25Q64 (8MB) SPI FLASH on Orange Pi Zero board.
Flashed SD card with Armbian_5.30_Orangepizero_Ubuntu_xenial_default_3.4.113.7z, followed all procedure (update, upgrade, etc)
Booted from SD without any issue.
Plugged 8GB pendrive in USB near ethernet connector
Installed armbian on pendrive (using armbian-config / install to sd nand ... menu)
Reboot, boot OK from pendrive.
dd if=/dev/zero count=4096 bs=1K | tr '\000' '\377' > spi.img
dd if=/usr/lib/linux-u-boot-dev-orangepizero_5.24_armhf/u-boot-sunxi-with-spl.bin of=spi.img bs=1k conv=notrunc
apt-get install flashrom
flashrom -p linux_spi:dev=/dev/spidev0.0 -w spi.img
flashrom error:
Error: Image size (2097152 doesn't match the flash chip's size (8388608 B)!
truncate spi.img -s 8388608
flashrom -p linux_spi:dev=/dev/spidev0.0 -w spi.img
shutdown -h now
Power off, removed sd card, power on

What I am doing wrong? MANY THANKS!!!
FOUND SOLUTION AFTER POSTED. NOW FIXED AND WORKING UHuuuuuu
I finally CAN boot from SPI flash+USB pendrive with NO SD card inserted.
Below are steps I did following all above and finally solved:
Copied /boot directory from SD card to PENDRIVE with armbian image (which had an empty /boot directory...).
Booted with both SD and PENDRIVE inserted
edited /boot/boot.cmd, set: "setenv rootdev "/dev/sda1", save.
compiled boot.cmd with: mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
edited /etc/fstab, commented lines for: /media/mmcboot and /boot
shutdown -h now
power off
removed SD
power on, boot
Voila!!! worked: booted from SPI FLASH + PENDRIVE with no SD inserted.
Sorry about my posts going back and forward.
Regards,
Adrian
