Design and Implementation of Fast Start and Recovery of CNC System Based on AM335x

Based on AM335x processor, this paper completes the fast start and recovery function of CNC system. This function is implemented in Uboot, using MTD technology to partition Nand Flash, configure serial port, LCD, USB and other pin clocks, and modify and add functions that check and update USB files. Finally, the Uboot transplanted on AM335x in this paper shortens the startup time of the CNC system, provides an LCD boot interface, and realizes the function of quickly restoring the CNC system from the U disk.
