Startup code and minimal runtime for the AMD Zynq7000 SoC to write bare metal Rust code. This run-time crate is strongly based on the startup code provided by AMD.

One major difference is that the MMU table is specified as Rust code. There are also modification to the stack setup code, because a different linker script is used.

This crate pulls in the cortex-a-rt crate to provide ARM vectors and the linker script.

Features

rt is a default feature which activates the run-time.

Re-Generating the MMU table

The MMU table is a static flat map of 4096 entries for each 1 MB in the memory map. It was generated using the table-gen binary tool.

You can re-run the tool using

cargo +stable --target <hostTarget> run --bin table-gen --no-default-features --features tools
