If you want to learn ARM, please help me recommend the ARM development board

Last time (April this year), I bought a friendly arm, 570 yuan. But it's time to reduce the price. It's okay, the information is relatively complete, including bootloader** (I heard that there are many boards, so when you buy it, you have to ask the boss if you have it).

worked, although I also did write drivers, but it had little to do with arm, and I wanted to sell it. What you want is cheaper for you, hehe. For more information, you go to ** to search for "friendly arm arm9 development board", it will definitely be cheaper than the ** they give, and there are as many things.

I use Fling's OK-2440-III board. It feels good, I recommend it to you. To sum up, this board probably has the following three advantages and one disadvantage.

1.There is a matching ** tutorial, and it is easy to get started by following the tutorial. Some of the tutorials for the distribution of development boards are from the Internet**, which is not the same as the board at all, and it is difficult to start.

2.The technical support is good, there are 400 free **, and the problems encountered during the operation can be solved in time. Some.

Under the banner of technical services, the company can't actually help solve the problem at all.

3.Versatile. In addition to the functions of general development boards, there are also infrared and temperature sensors, and IDEs

Hard disk interface module.

4.Cons: Expensive.

I use Weke's, the CPU is Samsung's S3C2410, this CPU is still quite common, it's pretty good

1. The ARM architecture is like the overall design of building a house, it is the big framework of the chip, it is a chip design scheme (architecture trace cover), and it is a public technical solution, and any grinding person can make a chip according to this scheme, but if the purpose of making a chip is to turn it into a commodity, it must be authorized by ARM. At present, all chip manufacturers in the world are designed and manufactured according to this scheme, and all software vendors also design software according to this standard, so the compatibility of products is not a problem.

2. Since its official establishment in 1990, ARM has made continuous breakthroughs in the field of 32-bit RISC (Reduced Instruction Set Computer CPU) development, and its structure has developed from V3 to V7. Since its establishment, ARM has been providing IP (intelligence property) to major semiconductor manufacturers for intellectual property rights, and has never been involved in the production and sales of Ziyouhao chips, coupled with the significant advantages of low power consumption and low cost of the core core designed, it has won the strong support of many semiconductor manufacturers and machine manufacturers, and has achieved great success in the field of 32-bit embedded applications, accounting for 75% above the 32-bit RISC embedded products market. It has established a market leadership position in low-power, low-cost embedded applications.

There are more than 50 large international companies that design and produce ARM chips, and domestic companies such as ZTE and Huawei Communications have also purchased ARM core cores for the design of communication chips.
