RDK Exclusive Command Usage

1. hrut_boardid

The hrut_boardid command is used to retrieve the ID of the current development board (different development boards have different IDs).

⚠️ The board ID affects hardware initialization during boot—please configure it with caution.

• Example command output:

  xxxxxxxxxx
  root@ubuntu:~# hrut_boardid
  0x6A84
  

• Output explanation:

  xxxxxxxxxx
  0x   6A          8             4
       ^^          ^             ^
       ||          |             |
    Chip ID   Board Power Design   Board Design Version
  

2. hrut_ps

The hrut_ps command prints process status information not supported by BusyBox's ps command, including process ID, parent process ID, priority, memory usage, virtual memory, and more.

• Syntax

xxxxxxxxxx
  hrut_ps

• Supported Information

• pid: Process ID. Each process in the operating system has a unique identifier called the process ID (pid), which is used to uniquely identify and reference a process within the system.。

• ppid:Parent Process ID. This indicates the parent process that created the current process.

• state

  : Process state.

  • I: Idle.
  • R: Running.
  • S: Sleeping.
  • D: Disk sleeping (uninterruptible sleep).
  • T: Stopped.
  • X: Dead.
  • Z: Zombie.
  • t: Tracing stop.
  • P: Parked.

• prio: Priority. Represents the scheduling priority of the process, usually expressed as a numeric value. A higher number typically indicates higher priority, making the process more likely to receive CPU time slices.

• nice: Nice value. Represents the scheduling priority as an integer. A lower nice value indicates higher priority, allowing the process to obtain CPU time more frequently.

• rt_prio: Real-time priority. Indicates the priority of real-time processes; a lower value signifies higher real-time priority.

• policy: Scheduling policy. Specifies the scheduling policy used for the process, typically a scheduling algorithm such as First-In-First-Out (FIFO), Round Robin (RR), etc.

• vsize: Virtual memory size. Represents the size of the virtual memory address space accessible to the process.

• rss: Resident Set Size (physical memory usage). Indicates the amount of physical RAM currently allocated and used by the process.

• comm: Command name. Contains the name of the command or executable file associated with the process, used to identify the process type or purpose.

3. hrut_somstatus

The hrut_somstatus command retrieves temperature sensor readings, CPU/BPU operating frequencies, and BPU load.

• Syntax

xxxxxxxxxx
sudo hrut_somstatus

• Common Usage

6.devmem

devmem is a command in BusyBox. It can read from and write to hardware registers by using the mmap function to map device memory into user space via the mmap method of the /dev/mem driver, thereby enabling read/write operations on physical addresses.

Syntax

xxxxxxxxxx
devmem ADDRESS [WIDTH [VALUE]]
  
  Read/write from physical address
​
        ADDRESS Address to act upon
        WIDTH   Width (8/16/...)
        VALUE   Data to be written

• ADDRESS: The physical address on which to perform the operation. This is a required parameter specifying the address to read from or write to.
• WIDTH: An optional parameter indicating the data width. It can be specified as 8, 16, or 32, defining the bit-width of the data to read or write. If omitted, it defaults to 32 bits.
• VALUE: An optional parameter representing the data value to write. If WIDTH is provided, VALUE must match the specified width. If VALUE is omitted, the command performs a read operation.

Common Commands

• Reading registers

xxxxxxxxxx
Read 32-bit: devmem 0xa600307c 32
Read 16-bit: devmem 0xa600307c 16
Read 8-bit:  devmem 0xa600307c 8

• Writing registers

Write 32-bit: devmem 0xa6003078 32 0x1000100
Write 16-bit: devmem 0xa6003078 16 0x1234
Write 8-bit:  devmem 0xa6003078 8 0x12
