swupdate-scripts : imx8mm modified partition

[DennisTseng]

Hi team,

I'm following  swupdate-scripts in AN13872 Enabling SWUpdate on i.MX 6ULL and https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/SWUpdate-OTA-i-MX8MM-EVK-i-MX8QXP-MEK/ta...

It mentioned the ramdisk of partition table need to fill into 42M:100M

But after Yocto build, my swupdate-image-imx8mm-XXXX.rootfs.cpio.gz.u-boot include some package and tools and the size up to 120M, so I shift the table in cfg_imx8mm_base.cfg.

And then the device cannot work.

Here is my question : 

1. Can I shift the table ?
   
   
2. Is the boot start address is a hardcore address (100M) ?
   I can not find the configuration or wks.in file descript it.
   
   
3.  Slot A and slot B can flexibly define larger sizes to prevent upgrades to new files from exceeding space ?

Hello,

Please also modify here and other PT table address referring your image layout.

Your image layout like this:

250:370

370:3370

3370:3490

3490:6490

Did you use -m to regenerate the MBR?
