STM32MP157F-DK2 cannot create .tsv when i try to increase rootfs size

Hi,

I am using the stm32mp157f-dk2, I'm using the core-image-minimal image and i'm trying to create a custom image. However, I would like to increase the rootfs size in order to add modules in the root filesystem once the kernel starts. I tried modifying the file /meta-st/meta-st-stm32mp/conf/machine/include/st-nachine-common-stm32mp.inc

IMAGE_ROOTFS_MAXSIZE ?= "2017660"

Then, i tried to modify the  /meta-st/meta-st-stm32mp/recipes-devtools/sdcard-raw-tools/sdcard-raw-tools/create_sdcard_from_flashlayout.sh file, just as the post 

DEFAULT_RAW_SIZE=4096 DEFAULT_ROOTFS_PARTITION_SIZE=2097152

I also modified the local.conf file

IMAGE_ROOTFS_EXTRA_SPACE = "1008830"

The problem i'm expecting is, the image built, but I see this message at the end of the build process

WARNING: quoia-custom-1.0-r0 do_create_flashlayout_config: >>> Cannot generate FlashLayout_sdcard_stm32mp157f-dk2-trusted.tsv file: the st-image-userfs-poky-stm32mp1.ext4 binary size (1167261696) for userfs partition exceeds the partition size (134217728).After that, i check the tmp/deploy/images/stm32mp1/flashlayout_custom-image/trusted/ directory and the .tsv files for the stm32mp157f-dk2 were not generated.

Please let me know if I am doing something bad or I'm misunderstanding some important concept, and sorry if my english is not that good.

Thanks

Hi,

I was able to solve the problem, I just modified my local.conf with the next line:

IMAGE_ROOTFS_SIZE = "1513245"

I also kept the same configurations in the  /meta-st/meta-st-stm32mp/conf/machine/include/st-nachine-common-stm32mp.inc file and /meta-st/meta-st-stm32mp/recipes-devtools/sdcard-raw-tools/sdcard-raw-tools/create_sdcard_from_flashlayout.sh file.

I am using the 5.15.67-stm32mp-r2 yocto kernel version.

The command i use is just bitbake <custom-layer-name>

In that layer i have some recipes in order to change my device tree and some configurations for dropbear to use ssh.

Thank you for your reply

Hi,

 

I did the test on my side and had no problems.
Can you give me more information about your set-up and handling?
Which version do you use?
What command did you make? 

 

Regards,

Grégory
