How to change the partition format from MBR to GPT

[Y_K]

Hi,

I want to create more than 4 partitions on emmc of i.MX 8m plus.

I read AN13706.pdf (Partitioning the Storage Medium on the i.MX 8M Family).
"4.2 Partitioning at the image deployment stage" has instructions for changing to mbr.
Q1) Is the default partition format of imx8m series gpt?

I'm currently using the images in LF_v5.15.5-1.0.0_images_iMX8MPEVK, but the partition format is configured as MBR.

Q2) Why is the LF_v5.15.5-1.0.0_images_iMX8MPEVK image configured with MBR? Do you have a reason?

Q3) Is it possible to change from MBR to GPT? Any problems?

Q4) Where should I modify to change from MBR to GPT?

Hi @Y_K,

I hope you are doing well.

Q)How to change the partition format from MBR to GPT?

[Ans]:

The default partition format of the i.MX8M series is MBR.
It is possible to change from MBR to GPT.
You should modify the wks file in yocto to change from MBR to GPT.

One can refer to 4.1 Partitioning at the image creation stage in AN13706.pdf (Partitioning the Storage Medium on the i.MX 8M Family).
