am437更换内核无法启动

5874 ARM

问答对人有帮助，内容完整，我也想知道答案 0 采用内核4.19.59编译完内核、模块、设备树后，将新编译产生的文件替换SD启动卡中rootfs分区对应文件，并安装模块到rootfs分区，系统启动卡在mmcblk1: p1 p2。请问各位大神这是什么原因？启动信息如下： U-Boot 2014.07-00115-g6c69db3 (Jan 30 2016 - 17:32:22) I2C: ready DRAM: 1 GiB NAND: 512 MiB MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 reading uboot.env Could not probe the EEPROM at 0x50 Could not get board ID.
