memcom

Memcom is a command line tool for interacting with the shared memory between the M4 and A7 processors of the ST32MP1XX controllers. It is based on the shared-mem-queue crate so it can be used to interact with applications which use that crate, too, or follow the protocol. For example, it can be used to write commands to or read logs from the M4 processor.

Features

The tool can operate a read channel (M4 to A7) and a write channel (A7 to M4) simultaneously. The channel origin and length can either be specified via the command-line arguments --read_origin, --read_length, --write_origin, --write_length or via a config file which is specified via the command-line flag --file (-f). As a fallback, ./memcom.toml is tried as default configuration file.

The config file has to be a toml file with the following syntax:

[read_channel]
origin = "0x10048000"
length = "0x2000"
[write_channel]
origin = "0x1004a000"
length = "0x2000"

Example

memcom --read_origin 0x10048000 --read_length 0x2000 --write_origin 0x1004a000 --write_length 0x2000
