//! Experiments with async on embedded. This code runs on nRF52840-DK.
//!
//! On ARM Cortex-M cores interrupt requests can wake up the processor even when
//! interrupts are disabled by a critical section. The executor runs in a critical
//! section and puts the processor to sleep when no futures is ready.
//! A pending interrupt request wakes up the processor (without jumping to the ISR)
//! and the executor re-polls the futures for completion.
//!
//! Only supports a single task called `main_async` which can never be
//! interrupted (bus faults and other exceptions disregarded).

EKS on Arm

The xarm-install-graviton2.sh script allows you to install and use Amazon EKS on Arm (xARM) with a single command. In essence, it automates the steps described in the docs.

Make sure you have aws, eksctl, kubectl, and jq installed, this will be checked on start-up and the script will fail if these deps are not present. So far tested with bash on macOS.

$ chmod +x xarm-install-graviton2.sh
$ ./xarm-install-graviton2.sh
