Hi,

I've reviewed the information you shared. Can you clarify one thing for me?
In the last line, "bootloader --ptable gpt," what does it entail? Here's
the scenario: I have a gpt.bin file that creates all the necessary
partitions, but I'm aiming to generate a wic image instead. What steps
should I take? Do I still require the gpt.bin file, or is there an
alternative approach?



bootloader --ptable gpt

will generate the GPT table based on the partitions defined in the same 
file.


wic is capable of generating the GPT table for you.

I believe wic source code is in 
https://git.openembedded.org/openembedded-core/tree/scripts/lib/wic.


Cheers,
Quentin

Hi,
I want to create a Wic image from total scratch. Like, i have a "gpt.bin" which creates 
the partition and put the required images in it. But, i want to reate a wic image which will do the 
same. So, for that do i need that "gpt.bin"? like, as per my knowledge wic cannot create 
the gpt partition please do correct me if am wrong. And i dont even have any .bbclass file which 
can help to create the wic image so please help me to generate this wic image from total scratch, 
what are the steps i need to follow, where i need to put the wks file and how i can write in the 
wks file.

FOR Eg: I need to have 6 partitions where i have a active and backup 
bootloader,kernel,rootfs so for that how we can write the wks file.



Have a look at what is done in meta-rockchip:
https://git.yoctoproject.org/meta-rockchip/tree/wic/rockchip.wks

This creates a wic image with 9 partitions and a GPT partition table.

Maybe https://docs.yoctoproject.org/dev-manual/wic.html could be useful 
as well. I'm not entirely sure we provide enough documentation for the 
wks file in the docs, so probably something we can improve, patches 
welcome :)


Cheers,
Quentin

[SIMON BABY]

I am also looking to format my eMMC card with 6 partitions with different
primary and secondary images. How can I achieve this using the wks file ?
