Hi,  
I am trying to integrate Mender with [DH electronics DRC02](https://www.dh-electronics.com/en/embedded-products/dhcon/detail/iot-gateway-drc02), which is based on [DHCOM STM32MP15](https://www.dh-electronics.com/en/embedded-products/dhsom/detail/dhcom-stm32mp15) system on module:

Firstly, I tried with automatic integration, but that was not working. So I started working on custom integration. I created fork of meta-mender-community: [https://github.com/jernejnose/meta-mender-community/tree/kirkstone/meta-mender-dhsom-stm32](https://github.com/jernejnose/meta-mender-community/tree/kirkstone/meta-mender-dhsom-stm32). And started modifying auto generated patch, as suggested in manual, but I can’t get image to build. I am using KAS: [https://github.com/jernejnose/meta-mender-community/blob/kirkstone/kas/dh-stm32mp1-dhcom-drc02.yml](https://github.com/jernejnose/meta-mender-community/blob/kirkstone/kas/dh-stm32mp1-dhcom-drc02.yml)

I get following errors:

> | arm-oe-linux-gnueabi-ld.bfd: env/common.o: in function `env_set_ulong':< | /media/jernej/d/build/tmp-glibc/work/dh_stm32mp1_dhcom_drc02-oe-linux-gnueabi/u-boot-mainline/1_2023.07.02-r0/git/env/common.c:55: undefined reference to `simple\_itoa’

I am stuck at this point for quite some time now. Does anyone have any idea how to fix this or what should be my next steps?

Thanks a lot for the help!
