I've inherited a custom board that contains (among other things) an STM32MP135AAE3, an eMMC, and an Ethernet controller (DP83826ERHBR). No SD card, no HDMI, no keyboard. For that matter, no JTAG (board error).
I had thought about running Zephyr but it's looking like that's not currently possible (discussion here).
The documentation for creating a Linux image for this chip seem to fall under two categories:
1) If you are using one of the development kits, here are explicit step-by-step instructions that will make it a joy
2) If not, here (thud) are the manuals for yocto, bitbake, repo, and really the entire Linux kernel. Read them all, digest them completely, and the answer will be obvious.
Am I missing something? Are there instructions somewhere to help me create a Linux image? I don't need to become a yocto expert, I just need to create one Linux image one time.
Thanks,
Chris
