I have a question about the partition size of an image generated by Yocto.
I am bulding for MACHINE=imx8mpevk using Yocto mickledore. The target is imx-image-core.
According to the wks file (in my case, the NXP's recipe chooses meta-freescale/wic/imx-imx-boot-bootpart.wks.in), the VFAT boot partion is 64MiB but the generated wic file says it's 83.2MB.
Likewise, when I manually set IMAGE_ROOTFS_SIZE to 2GiB or 3GiB, the actual root FS partition sizes are 2.6GiB or 3.9GiB, respectively.
I confirmed that the env file given to wic (/tmp/sysroots/<MACHINE>/imgdata/<IMAGE>.env) contains correct numbers.
Why every partiton is about 30% larger??
