Boot from SD / EMMC with root filesystem on SATA SSD

CM4s will not boot directly from an SSD over SATA, but you can boot from SD / EMMC and mount the root filesystem from an external disk.

• This does not apply to you if you are using NVME
• This does not apply to you if you are using USB

Requirements

• A Turingpi2
• A CM4 module (lite or with EMMC)

A few Nomad examples. Nomad is great and is worth considering as an alternative to k3s and docker compose.

These playbooks are for compiling the Pi OS kernel to make it compatible with Envoy which is used under the hood of Cilium, Consul Connect and maybe Istio. Enyoy will refuse to start on Pi OS due to a memory allocation error. Long discussion here. The two options are

• Building Envoy from source (not fun)
• Compile the Pi OS kernel with some extra flags (not fun, but doable)
• Use Ubuntu or maybe Debian built for the Pi (not fun either)

Pi OS needs to be compiled with the following options:

CONFIG_ARM64_VA_BITS_39=n
CONFIG_ARM64_VA_BITS_48=y
CONFIG_ARM64_VA_BITS=48
