  Hi, 

  On Yocto hardknott_1v5 tag build it is not possible to save U-boot environment. 

  I have the following error

  Environment size: 2331/4092 bytes
  u-boot=> saveenv
  Saving Environment to MMC... Writing to MMC(2)... MMC: block number 0x2008 exceeds max(0x2000)
  failed
  Failed (1)

  How can i solve this ? 

  My image is on eMMC device.

  Hello, 

  Happy new year too . 

  I built the image with bitbake imx-image-multimedia . then flashed the image imx-image-multimedia-lec-imx8mp.wic.bz2 with balenaEtcher . 

  The system starts well but no saveenv in u-boot.

  I tried with dd command too with the same behaviour .

  To bypass the issue i dd my rootfs on /dev/sda2 on another sdcard with original LEC-IMX8MP-2G-IPi-SMARC-PLUS_Yocto-hardknott_V1_R3_2022_11_17 image then copied  the kernel , dtd .

  Regards

  Hi , 

  I succeeded to solve this issue by reflashing LEC-IMX8MP-2G-IPi-SMARC-PLUS-UUU-TOOL_20220309 with uuu (but with uuu Git version) .  Your uuu version does not work for me.

  Can't explain what's the root cause .
