在外部 USB 硬盘中为 i.MX8 构建 Yocto

Question

I'm trying to build an image using bitbake for the i.MX8 board. I'm following these instructions:

https://www.nxp.com/docs/en/user-guide/IMX_YOCTO_PROJECT_USERS_GUIDE.pdf

Since I do not have enough space in local HDD, I'm using an external USB HDD (I have other unrelated stuff stored in this HDD).

I have been successfull at executing the imx-setup-release.sh script in that document, with which I built a configuration for the imx8mm-lppddr4-evk machine using the fslc-wayland distro.

However, when I try a command, such as "bitbake core-image-minimal", I get several failed tasks. It seems that the common deminator is the fact that, for some reason, when the path to my build folder is passed (which is within the external HDD), it is considered an invalid argument.

I get messages such as this:

OSError: [Errno 22] Invalid argument: '/media/home_dir/427AD2297AD2198D/imx-yocto-bsp/build_fslc_wayland_imx8mm_lpddr_evk/sstate-cache/95/51/sigtask.1jbsd4s4' -> '/media/home_dir/427AD2297AD2198D/imx-yocto-bsp/build_fslc_wayland_imx8mm_lpddr_evk/sstate-cache/95/51/sstate:core-image-minimal:imx8mm_lpddr4_evk-fslc-linux:1.0:r0:imx8mm_lpddr4_evk:3:955169ece771b852dc433575442e7ed805ac56cbcb1ebd3aa913a632da23a46b_clean.tgz.siginfo'.

It seems that bitbake is having trouble parsing the path to my HDD (that 427AD.../ folder).

What should I do to fix this?

Answer 1

The issue was that my HDD was not formatted with an ext4 format. Once I did that, those errors went away.
