cortex-gnat-rts
This project contains various GNAT Ada Run Time Systems (RTSs) targeted at Cortex boards: so far, the Arduino Due, the STM32F4-series evaluation boards from STMicroelectronics, and the BBC micro:bit (v1) (by simonjwright)

The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Writing Startup Code for STM32 in Completely Ada
Also, u/simonjwright 's cortex-gnat-rts was most helpful.
-
Define project-wide allocator on bare application.
You could look at providing your own version of System.Memory - this was easy enough in an embedded system with a restricted runtime, but much hairier in full Ada.

Ada on ESP32 and FreeRTOS
It includes a customized GNAT RunTime (besed on cortex-gnat-rts) and a ESP32 toolchain binaries. It's integrated in Espressif IoT Development Framework build system.

Clarification on Finalization
I looked into finalization without exceptions for Cortex GNAT RTS, branch finalization, not touched since 2018; not too difficult (largely reinstating stuff I’d cut out because of restriction No_Finalization).
-
Spunky (Kernel written in Ada) #4: Kernel Timing
What I had in mind was the usage generated by AdaCore’s SVD2Ada, e.g. the register without the pragma, and the place in the wider data structure in which it’s used, with the pragma.

Array copies on bare metal using GNU GNAT generate library calls
This code, which I unthinkingly wrote thinking "how clever!", in fact calls memcpy() and memset() under the hood, which works because the compiler was built including Newlib.

Please explain secondary stack to a C programmer!
.. and a simple version here.

What are you working on? July 2021
So Rose happened because years ago there was a research OS (Coyotos) which sounded interesting, but it disappeared some years ago. I took the system call interface and hierarchical interface idea, created a run time using the Ada bare bones repository, and went from there.
