iMX28 python3 via Yocto 1.6.11

jfm — Mon, 08 Feb 2021 22:00:33 GMT

SYNOPSIS: A device based on the iMX28 requires updates to installed images created via Digi Embedded Yocto to include Python3 support. Specifically, I am starting with the Digi ConnectCard imx28 JumpStart board and its Yocto ecosystem.

Based on a literature review, the Digi support for this platform via the ConnectCard imx28 JumpStart board (i.e. ccardimx28js) appears to stopped in its DEY 1.6.11 release.

Working with that constraint, I have attempted unsuccessfully to include python3 in the Yocto. Is there a way to provide python3 support for ccardimx28js via DEY 1.6.11 (or any more modern DEY that may support this platform that I missed)?

Here's the first steps I tried.

I build by adding the following to my local.conf configuration file for DEY 1.6.11.

IMAGE_INSTALL_append = " python3"

I see the python 3.3.3 recipes being built, and these recipes appear to succeed. However, the final step to package them into the root file system fails.

Specifically, the log for the do_rootfs task shows the following errors.

1 DEBUG: Executing python function rootfs_process_ignore
2 DEBUG: Python function rootfs_process_ignore finished
3 DEBUG: Executing python function rootfs_runtime_mapping
