File transmission through serial ports between the embedded Linux System and the host 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

Install minitools + minitools in Ubuntu and download linux to the Development Board.1. Install minitools in Ubuntu 1. Find the MiniTools-Linux-20130513.tgz, which is in the mini2440 CD linux platform tool folder 2. I copied it to my/home/lianghuiyong/Linux_share/directory. 3. # cd/opt/FriendlyARM/mini2440 4. # tar xvzf/home/lianghuiyong/Linux_share/MiniTools-Linux-20130513.tgz 5. # cd/opt/FriendlyARM/mini24

workaround for the type of library is to recompile the library file you need, the platform is arm , so all the libraries must be Arm , the third type of error only needs to be added in the appropriate location.The -l/usr/testlib here is the path to my dynamic library.Then continue makeError reason: This is the third case, there is no library file that calls the callThe resulting error is generallyWorkaround:The other mistakes are the same, and the solution is the same.The executable file will

You can see from the 6410 Data Manual that the memory start address should be 0x50000000, while the Linux kernel loaded by U-boot is loaded to 0xC0008000 during the use of the real6410 Development Board, I guess (I have not read the code to verify the speculation) this is because the Linux Startup kernel address is 0xC0008000, and U-boot also maps the memory to keep consistent with Linux, easy to use. Next,

there is no with_ffmpegworkflow, and add it in cmakecache.txt. With_ffmpeg, started to compile according to the previous method, install to the tool chain, compile the TLD algorithm, no error is reported. However, put run_tld on the Development Board for testing. The error is still the same --Capture device failed to open!. It's almost three weeks. Please be depressed .... PS: At the same time,

Re-run the entire system: U-boot, kernel, and file system. 1. The U-boot program is the same as the Program for burning bare boards. 2. Run the kernel: The Development Board is set to nor. If the NAND Flash contains U-boot, it can be started with nand. Dnw and TFTP. Dnw: Enter "k" in the menu, and then use" dnw.exe "to send the uimage file. TFTP: TFTP 30000000 uimage Nand erase Kernel
