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
...

$(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.

Check my tutorial and more info about SPI in R2S.
p.12 from your tutorial ...Now write this image idb_finish.img to MMC card and boot NanoPi with this card.
How to write idb_finish.img to SD card ?
dd if=idb_finish.img of=/dev/sdx
or any other way ?
Yes. Exactly this way. Or in Windows use Win32DiskImager.
After that NanoPI does not boot anymore

Can you share Your idb_finish.img so i can check?
Sure.
idb_finish.img and other files are in the zipped file nanopi_rk3328.zip on the turbobit nanopi-rk3328.zip.
Is only one difference between your tutorial and what I have done. In the p. 11 your tutorial you have
export BL31=../arm-trusted-firmware/build/rk3328/release/bl31/bl31.elf
but I have not in my arm-trusted-firmware folder bl31.elf file. Sorry but I do not remember where I found the bl31.elf file, I included it to the zip file.
Did you check my idb_finish.img file ?
Works like a charm

Thank you for your hard work
Sorry had no time to responde because of family problems. What you did wrong earlier?
As I said earlier, when compiling arm-trusted-firmware, the BL31 file was not created. The reason was that I had the BL31 variable set to my wrong (from Internet) bl31.elf file.
When I removed this variable, (unset BL31) then the arm-trusted-firmware/build/rk3328/release/bl31/bl31.elf file was created and after setting the BL31 variable (export BL31=.....) and compiling the uboot, everything started working wonderfully.
I have one question for you. Do you have any idea how to run OpenWrt from SPI Flash (I have a W25Q128 soldered in) ?
Did anyone have a working guide to expand space for packages on sd with squashfs image ?
