SPI boot should work as long as u-boot and kernel (+ device tree) has support for it. While the u-boot that Armbian used can successfully detect my W25Q256 chip (only the lower half is usable due to the lack of 4-byte addressing support), I haven't tried actually reading/writing to the flash in u-boot yet.
SD card is very convenient, SPI flash chip need to welding is not necessary to use.
it is entirely possible to boot from the SPI. I had an R1S. I would post my 1,189 line boot log from the serial console, but nobody wants to see that. Yes it has U-Boot + .scr file you can edit/replace.
SDCard = $9 for an EVO 64GB last time I bought one. The easiest boot media.
eMMC pluggable socket = higher performance and reliability than SDCard, but R1S/R1S doesnt have a nice friendly upright socket. Prices range from $29 to $99 for 64GB 5.1 eMMC. Get yourself an M4V2 and stop wasting time.
SPI = the most frustrating, illogical, poorly documented PLEASE-BRICK-ME option. I dont care if its $1 or $99, I hates it. Quick, are you fdt or dtb? You're gonna *#$#(% up at some point.
How much did it improve temps? My 2 NanoPi were sent yesterday, so i'm gonna have to wait a month to test things
Please have a look at this topic where I am sharing initial (very promising) test results of OpenWRT on the R2S -- thanks @jayanta525

Do you have your modifications in a repo where we can take a look?
I see you noted CONFIG_IRQBALANCE. It’s interesting because I had tried irqbalance as well but found it didn’t separate eth0 and eth1 to different cores.
What kind of load were you putting on your NanoPi during the screen capture?
Hi, I am trying to boot openwrt from orangepi r1 plus spi but don't know how to start
like editing dts modifying uboot etc. Could you help me please?
Hi,
i tried some things to bring mtd nor flash support
- i compiled this repo to run openwrt on my sd card https://github.com/jayanta525/openwrt-nanopi-r2s
then mtd not exist in default shown below.
root@OpenWrt:/# cat /proc/mtd
dev: size erasesize name
- i started to add SPI node to rockchip.dtb found in my sd card's mmcblk0p1 partition
i converted dtb to dts and add SPI support changes shown below (if it is true, please check)
right side original one, left side modified one to support SPI

So i will try to modify uboot any help would be appreciated..
Please refer to this thread: Xunlong Orange Pi R1 Boot from Flash
You'll find the appropriate modifications in the discussions.
As for RK3328 SoC, I will order a 16M SPI flash and test it out in a while, and will post back here.

In addition to uboot modification, some openwrt makefile modifications is required along with kernel_config.
Please start fresh with a fork of openwrt upstream.
first of all, SPI partitions in uboot must be added via a patch file, and then in linux dts.

Hi,
Thanks for your interest,
3.)
i have edited makefile like shown below and compiled openwrt it gives me 5.9M sysupgrade image
...

### Devices ###

IMAGE/sysupgrade.bin = append-kernel | append-rootfs | pad-rootfs | \
append-metadata | check-size $$$$(IMAGE_SIZE)
endef
include $(SUBTARGET).mk
$(eval $(call BuildImage))
4.) i have cloned this uboot repo > https://github.com/u-boot/u-boot.git
and added spi booting options to nanopi-r2s-rk3328_defconfig shown below and compiled uboot
CONFIG_SPL=y
CONFIG_CMD_SF=y
CONFIG_CMD_SPI=y
CONFIG_DM_SPI=y
CONFIG_DM_SPI_FLASH=y
CONFIG_SPI_FLASH=y
CONFIG_SPI_FLASH_MACRONIX=y
CONFIG_SPI_FLASH_WINBOND=y
CONFIG_SPI=y
CONFIG_SPI_MEM=y
result images are :u-boot.bin u-boot.cfg u-boot.cfg.configs u-boot.dtb u-boot-dtb.bin u-boot-dtb.img u-boot.img u-boot.itb u-boot.its u-boot.lds
which image should i flash to SPI flash and i don't know below partitioning is true i moved this flash parts from opir1 . Can you help me this point?

@alfa I would suggest opening up a new thread for the discussion.
Please post the same in the new created thread.
We will continue the discussion over there.

I have the NanoPi R2S board with me. I will solder a 4MB flash and test out the configurations first.
Meanwhile please wait for input from different users, might be helpful for troubleshooting later.
EDIT: Just found out I only have an 2MB flash. OpenWrt won't fit in here.
Please follow up on the original thread.
