Spawn a process & Read an ELF File

This crate is based on the one in services/test_spawn. The main difference is that this one has the ability to read, load, and execute an ELF file through the opcode LoadElf.

API

The following messages are supported:

Mnemonic Opcode Type Description
LoadElf 1 M Reads and loads an ELF file sent as a MemoryMessage. Offset is used to determine where the file starts
PingResponse 2 S Returns the scalar sent except that arg1 += 1

A Note on Building

In case you need to recompile this program for use in app-loader, use the following commands:

$ cargo build --package spawn --target riscv32imac-unknown-xous-elf --release
$ cargo run --package tools --bin copy-object target/riscv32imac-unknown-xous-elf/release/spawn
$ cp target/riscv32imac-unknown-xous-elf/release/spawn.bin apps/app-loader/src
