Milkv duo support NAND image

[Markus250]

In buildroot I can compile image for SPI NAND next command:
./build.sh milkv-duo-spinand
and in the folder out/
I will receive the files for the firmware nand (boot.spinand, fip.bin, rootfs.spinand, system.spinand)
I load this into nand and it works
How can create an image for nand using this layer (yocto)?

sorry for my eng

This broke the build for me:

Yep, It doesn't work, I have exactly the same error
I am check fiptool.py args, he does not have --NAND_BOOT=1
Vishwanath Martur (@vishwamartur) you make patch forfiptool.py?

Marcel Ziswiler (@ziswiler) Markus250 (@Markus250) I have removed the non existing option for now. I assume there is a patch for https://github.com/milkv-duo/duo-buildroot-sdk/blob/develop/fsbl/plat/cv181x/fiptool.py which is missing, or the option was added wrongly.

I have a patch here #510
can you test it out and see if it un-breaks you.

[Markus250]

Khem Raj (@kraj) Yes, without this argument, the assembly of the image has advanced. Also, I had to comment the line
cp ${WORKDIR}/fip.bin ${DEPLOYDIR}/ in file milkv-duo-bootfiles.bb because in recipe milkv-duo-bootfiles.bb and milkv-duo-fsbl.bb simultaneous copying of the file fip.bin
But it still did not work, files rootfs.spinand, boot.spinand, etc.. do not appear, do not even gather =(
How much I could make out buildroot this files make python script mkubiimg.py, example from duo-buildroot-sdk/build/Makefile:
${Q}python3 $(COMMON_TOOLS_PATH)/spinand_tool/mkubiimg.py --ubionly $(FLASH_PARTITION_XML) ROOTFS $(OUTPUT_DIR)/rawimages/rootfs.sqsh $(OUTPUT_DIR)/rawimages/rootfs.spinand -b $(CONFIG_NANDFLASH_BLOCKSIZE) -p $(CONFIG_NANDFLASH_PAGESIZE)
Again, these are all my assumptions, I could never collect the image of NAND through Yocto
I will be grateful if you help me)

Markus250 (@Markus250) does the fix proposed in #511 fix the issue ?
