Hi, I am trying to build the Yocto base image using the instructions [balenaOS - Docs](https://www.balena.io/os/docs/custom-build/). I have tried both Ubuntu 20.04 & 22.04 - the instructions do not work. Something is missing. We have a paid account for Balena account and we would like to start customising our build. I am trying to build v2.88.v-rev4. On the same machines, the standard Yocto builds perfectly fine. However, Balena OS version of it using BARYS fails. Which OS should we be using (Ubuntu 22.04 or something else?) What are the instructions to build v2.88.v-rev4? Or is there a more up to date version of the doc? ---

Hi @kumar-bala, Let’s see if we can sort out the issue: - Can you share what hardware you are trying to build for? - When you say the instructions don’t work, can you share more details about which step in the process particularly doesn’t work and in what way (something doesn’t load? there is an error message? etc.) ---

Hi, are you able to clone the binutils repository from the same host computer you are building from, like: ```auto git clone git://sourceware.org/git/binutils-gdb.git ``` ---

Yes - I can. I have removed the build directory and restarted the build. Just to check if it is an issue with the downloads folder on Yocto. I have 300GB hard drive. I believe this build only needs about 150GB? ---

Hello @kumar-bala if you use ` --rm-work` it might be enough. Anyway, the build will fail with a clear `not enough space error`if that’s not the case.
