An error occurred while porting the uclinux2.6 kernel to B0! Help! -- Linux general technology-Linux programming and kernel information. The following is a detailed description. I use the kernel 2.6.14 and u-boot for loading. I will list the problems and my understanding during the porting of the uclinux2.6 kernel to b0x. During the porting process, I used a simple driver. After necessary modifications, the kernel is compiled and run properly, the fol

It is easy to understand with the standard design of simulated prototype filter. 2. Low-level design can be used for implementation and high-speed operation. 3. For a design scheme with the same tolerances, the order number is shorter than that of FIR. 4. Closed-Loop design can be used. Disadvantages: 1. Non-Linear

the direct purpose of econometrics research is to determine the total regression function Yi=b1+b2xi+ui, however, only the observed values from a number of samples can be obtained, and the sample regression function established with sample information is as close as possible to "To estimate the total regression function. Therefore, it is possible to determine the criteria for establishing a regression function from different angles, and there are many methods to estimate the parameters of re

massive data processing because it separates the datasets as expected. This allows us to split the datasets into more manageable data, then use a merge sort to process the data and then merge the data continuously, without having to store all the data at once.Polynomial interpolationA method of finding the approximate value of a function. Where the function value is known only on a few points. The basis of this algorithm is to establish an interpolation polynomial pn (z) with a progression of l

This section reminds everyone of the mathematics they have learned in high school. The equation with the maximum number of unknowns in the equation is greater than twice. It is called a high-order equation. The idea of high-order equation solution is to convert high-order equations into low-frequency equations through appropriate methods. There is no universal algebraic solution and root-seeking formula for a single-dimensional high-order equation of five or more times (that is, it cannot be sol

Dr. Hanks is a well-known expert in the field of BT (Bio-tech, Biotechnology) whose son is named Hankson. Now, Hankson, who just came home from school, is thinking about an interesting question.Today in class, the teacher explained how to ask for two positive integers c1 and C2 greatest common divisor and least common multiple. Now that Hankson thinks he has mastered this knowledge, he begins to think of a "inverse problem" of a "number of conventions" and "common multiple", the question of whic
