I think if I want to download something from my PC to the embedded Linux System of the Development Board, many people will first think of using network tools such as TFTP SFTP to download it from the network port. But if the network is not used, what should I do if I can only download it through the serial port? At this

In this chapter, we will briefly study the development process of the uC/OS system based on niosii. There are three tasks in the experiment: the first task is used to drive the DS1302 real-time clock, the second task is used to flash the LED lamp, and the third task is used to di
I. Causes and principlesCause: In the past computer burning write bootloader to NAND is using JTAG and Jflash,jtag is connected with the port, the current computer is generally not the same mouth, now generally used cheaper to start the J-link, using USB, you can no longer use the previous Jflash burned write. It is therefore necessary to find a way to J-link write NAND. The following instructions j-link the principle of burning nand. With the realarm2410 De
First, install the Serial debugging tool: MinicomThe Development Board has a serial port. Can be connected to the PC via serial cable. The Linux driver sends debug information to the PC via a serial cable while outputting debugging information, so the Linux driver can view debug information directly on the PC.Note: Since many new PCs and laptops do not have a serial port, it is recommended that readers buy

select project -- Build options. Go to the compiler Selection: Select gun arm GCC complier, and add the-G parameter to the first one so that the compiled program can be debugged by arm GDB. OK. After the compiler is selected, set the compiler settings --- complier and debugger. Select the compiler to set. Here, the gun arm GCC complier selects the toolchain executables label. It should be noted that the following complier C ++ complier linker .... All are the cross-compilation tool chains of th
