After OpenWrt compiles the tool chain and SDK, you may have the following error:
zchx@zchx-system-product-name:~$ mips-openwrt-linux-g++ mips-openwrt-linux-uclibc-g++.bin:environment Variable " Staging_dir "Not defined
The solution is simple, that is, compile the SDK also choose to compile, in the compiled SDK, including the tool chain. The tool chain here will not be an error. Good time.Zchx@zchx-system-p
), when the TLB refill exception occurs, the hardware automatically jumps to the ebase corresponding address execution.
* * memcpy (void *) Ebase, Tlb_handler, 0x80);
...
}
It can be seen that the TLB refill exception processing function code, is the kernel dynamic settings, rather than the assembly of static code, due to the MIPS hardware model more, so the operation more flexible.
Also, note that the
This part of the record is kernel upgrade, before on the FPGA ran 2.6.29 kernel to verify the function of some IP.The source code for Android from Google's website is not part of the kernel, and kernel needs to be downloaded separately.A version of 3.0.72 was found after downloading from Google.So the record here is the process of kernel upgrading from 2.6.29.4 to 3.0.72.The first idea is to find a 3.0 on the MIPS architecture of the config file, and

MIPS Technologies Monday, the Institute of Computing Technology of the Chinese Academy of Sciences (MIPS32) has obtained the authorization of the MIPS64 architecture, which will be used to develop the godson CPU.

MIPS is a shining star in high efficiency, low-power CPU design principles and has been in the mobile and embedded industries for nearly 30 years. This article will quickly explore the evolution of the MIPS architecture and describe how it evolved from the earliest version of Stanford University's Computational Science lab to the current architecture.

You may have heard about Google TV that is coming soon in our homes, through Android set-top boxes. it's expected to come out this fall, but the source code of the MIPs port is already available to the public. it is important to note that android was originally designed for smartphones, which commonly use arm processors. however, in the set-top box market, MIPS-based systems are quite popular. this is why t

The ABI is the abbreviation for the application Binary interface, which identifies the operating mode of the processor and the encoding format of the specification target file.
The MIPS instruction set architecture formally supports the 64-bit mode of operation since MIPS3, so the code can follow O32 (o meaning old), N32 (n meaning new) and N64 Abi.
O32 and N64 are pure 32-bit and 64-bit modes, which, in addition to the length difference

1. Kernel stack Switching (MIPS)
When a dispatch switches to a process, the *KERNELSP is set based on the value of the task_struct->thread_info (the bottom of the kernel stack of the process currently running), and the value is Thread_info + thread_size-32 (MIPS, using SET_SAVED_SP macros).

The instruction set can be divided into complex instruction set (CISC) and thin instruction set (RISC) two parts, representing the architecture are x86 (CISC),ARM and MIPS (RISC)respectively.arm- RISC is a chip system designed to improve processor speed, and its key technology is to complete multiple instructions in a single clock cycle. Compared with the complex instruction set CISC, the instruction set of the ARM instruction sets with RISC archite
