Recently, I want to learn about the arm Development Board and develop bare metal programs as per the single-chip microcomputer routine. Baidu, most bare-metal programs are developed using rvds or ads, and written to SDRAM using jlink or JTAG for execution. Because I am used to it in Ubuntu and want to break away from the integrated development environment, I will use arm-Linux-GCC and other tools for development in Linux. The first problem I encounter
