A Linux command to check the router CPU chip architecture

What is CPU chip architecture?

How to check the CPU chip architecture of Linux processor? Is the CPU 32-bit or 64-bit?mipsWhat is it?
The first step to flash the router firmware is to figure out what the router's CPU is, and then you can find the corresponding version of the firmware and flash it in. Flashing the wrong firmware will cause the router to fail to start or a certain function to be unavailable, etc.
For example, if you install v2ray software on a router, v2ray is not universal for all systems. It also distinguishes CPU chips. So there is the following scenario.

V2Ray is available on the following platforms:
Windows 7 and later (x86 / amd64);
Mac OS X 10.10 Yosemite and later (amd64);
Linux 2.6.23 and later (x86 / amd64 / arm / arm64 / mips64 / mips);
Including but not limited to Debian 7 / 8, Ubuntu 12.04 / 14.04 and later versions, CentOS 6 / 7, Arch Linux;
FreeBSD (x86 / amd64);
OpenBSD (x86 / amd64);
Dragonfly BSD (amd64);

It is easy to distinguish between x86 and amd64 under Windows. One is Intel and the other isAMDWhat are arm and mips?
Let me introduce you to the ARM architecture and MIPS architecture!
What is ARM Architecture:
ARM official website:https://www.arm.com/
ARM architecture, formerly known as Advanced RISC Machine, is a family of RISC processor architectures that are widely used in many embedded system designs. Due to its energy-saving features, it has also made many achievements in other fields. ARM processors are very suitable for the mobile communication field, in line with its main design goals of low cost, high performance, and low power consumption. On the other hand, supercomputers consume a lot of power, and ARM is also seen as a more efficient choice. ARM architecture is divided into 32-bit and 64-bit.
What is MIPS Architecture:
MIPS official website:https://www.mips.com/
The MIPS architecture is a processor architecture that uses a reduced instruction set. It appeared in 1981 and was developed and licensed by MIPS Technologies. It is widely used in many electronic products, network devices, personal entertainment devices and commercial devices. The earliest MIPS architecture was 32 bits, and the latest version has become 64 bits.
Now that we know about ARM architecture and MIPS architecture, how do we know which CPU the router has?Chip ArchitectureWoolen cloth?
After setting up the router, SSH into the router system. After entering the system, you only need one command to quickly check the CPU architecture.

uname -m

Enter the uname -m command to directly display the Linux version kernel information.

uname -a

If you want to know more about the CPU hardware information of the router, you can use the cat command to view it.

cat /proc/cpuinfo

Now that you know the CPU architecture information, let's find the software that corresponds to the CPU version to configure the router!
