`Minimalist binary crate for ASPEED

Based on the template for building applications for ARM Cortex-M microcontrollers

Dependencies

To build embedded programs using this template you'll need:

• Rust toolchain.

• rust-std components (pre-compiled core crate) for the ARM Cortex-M targets. Run:

$ rustup target add thumbv7em-none-eabihf

Building this app

$ cargo build --release

Using this app

1. Start the JLinkGDBServer:

   JLinkGDBServer -device cortex-m4 -if swd

2. Run the program with GDB:

   gdb-multiarch target/thumbv7em-none-eabihf/release/aspeed-ddk
   

3. Enable semihosting in GDB:

   target remote :2331
   monitor semihosting IOClient 2
   load
   continue

Generate Image for AST1060

• Generate Image for Programming

  cargo build;cargo objcopy -- -O binary ast10x0.bin

• Generate Image for Boot from UART

  cargo build;cargo objcopy -- -O binary ast10x0.bin
  scripts/gen_uart_booting_image.py ast10x0.bin uart_ast10x0.bin

Runing the app on QEMU

Build QEMU

1. git clone https://github.com/qemu/qemu
2. Run the following commands to build qemu

   mkdir build
   cd build
   ../qemu/configure --target-list=arm-linux-user,arm-softmmu,aarch64-softmmu,aarch64-linux-user,riscv32-softmmu --enable-docs --enable-slirp --enable-gcrypt
   make -j 4

Run

1. Run the image in QEMU using ast1030-evb machine

   qemu-system-arm -M ast1030-evb -nographic -kernel ~/work/rot/aspeed/aspeed-rust/target/thumbv7em-none-eabihf/debug/aspeed-ddk
