Yocto Linux for imx8mm evk Board.
I`ll store some info into nvram, such as SN number. While the partition cann`t be ereased when download again.
Two workarounds would be thought of.
One is to store info before download, and download all with SN again.
The another workaround is to reserve the partition all the time.
I prefer the second way.
Could you give me some tips?
How to position the u-boot address in the MMC using uuu? How to create parition while using u-boot or other ways?
....
Anything would be appreciated.
Which version BSP are you using? And are you using emmc or SD card?
Hi, Rita:
1. Linux imx8mmevk 4.14.98-imx_4.14.98_2.0.0_ga.
2. emmc.
You can refer to the chapter 4.3.3 Partitioning the SD/MMC card of enclosed file.
you can find your sdcard layout here, then you can set as you need,generate new class file
