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.

Some major differences:

No L2 cache initialization is performed.
MMU table is specified as Rust code.
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
