你好,我想咨询下 uboot 编译相关的问题,
开发板 : IMX6ULL_PRO
开发环境 :
Linux version 5.15.68.1-microsoft-standard-WSL2 (oe-user@oe-host) (x86_64-msft-linux-gcc (GCC) 9.3.0, GNU ld (GNU Binutils) 2.34.0.20200220) #1 SMP Mon Sep 19 19:14:52 UTC 2022
我按照 “嵌入式Linux应用开发完全手册V5_IMX6ULL_Pro开发板.pdf" 下载了 BSP, 配置了交叉编译工具链,在按照 “6.2.2 编译 u-boot 镜像” 编译时遇到如下问题
