Download uboot to nandflash of s3c2442, using Openocd?

Download uboot to nandflash of s3c2442, using Openocd? -- Linux general technology-Linux technology and application information. For details, refer to the following section. Dear friends, have you downloaded uboot to Samsung s3c2442's nand flash? I have encountered a problem. If I use jlink to burn it, I will only burn it indirectly, that is to say, we need to first burn the data into the sdram, and then use the existing Uboot in the board to move the data to the nand flash, but there is no uboot on the board itself. What tools should we use to burn the data, some information on the Internet Prompts openocd, but I cannot connect the configuration file. How can I configure the file?
This is the interface for running openocd.
