Hi there,

i am currently working on porting Mender to the RK3566 platform, namely by the use of the Radxa CM3 hardware.

I have adapted the mender-convert project config for the RockPro64 to build U-boot for the RK3566.

However it always gets stuck at ‘Error: “mender\_setup” not defined’

Mender setup is defined in env\_mender.h which is included in env\_default.h so i don’t really understand why it can’t seem to find it.

This is the stacktrace i am facing:

```auto

Where is your BSP u-boot and kernel come from? I suggest you integrate on the Debian provided by Radxa.

Sorry i should have elaborated that more clearly:

I used mender convert, based on the rockpro64 config, and replaced the U-boot with the one from

[GitHub - radxa/u-boot: U-Boot tree for pending commits](https://github.com/radxa/u-boot) using branch stable-4.19-rock3  
I then proceeded to manually integrate all the patches that didn’t automatically integrate into the uboot sources.  
building like this:

```auto
make radxa-cm3-io-rk3566_defconfig
make
make BL31=rkbin-tools/bin/rk35/rk3568_bl31_v1.32.elf u-boot-dtb.bin spl/u-boot-spl.bin u-boot.itb
make envtools

tools/mkimage -n rk3568 -T rksd -d rkbin-tools/bin/rk35/rk3566_ddr_1056MHz_v1.10.bin rksd_loader.img
cat spl/u-boot-spl.bin >> rksd_loader.img
dd if=u-boot.itb of=rksd_loader.img seek=448 conv=notrunc

```

The rest of the BSP comes from the stock Radxa Debian, where mender-convert added the mender client.
