At this point, in Linux at least, the partitions disappear because 1k offset for u-boot overwrites part of the GPT table. However, apparently this is OK because u-boot can read the backup GPT table at boot time. So, if I have my board set up to boot from the sdcard (sd3 in my...

U-Boot 的全称是Universal Boot Loader,其作用就是引导系统。对于我们熟悉的 PC,上电后,通过 BIOS 引导操作系统 (Windows、Linux等)。对于嵌入式系统一般将这个引导程序称作 BootLoader,U-Boot 就是目前使用得最广泛的 BootLoader。 在前面的文章中,QEMU直接引导鸿蒙系统的 Linux 内核,这种方式缺少灵活性,关键是在实...
