树莓派官方系统Raspberry Pi OS 共有2个分区,root分区和boot分区 boot分区: 启动分区,放置系统启动、驱动文件,分区格式为Fat32. root分区:、 根分区,主要用来存放系统配置信息和配置目录等。分区格式为EXT4. 树莓派系统备份: 其实就是对boot分区和root分区这两个分区进行备份。
SD 卡将用于存储引导加载程序和根文件。所以,我们首先在其上创建两个分区 - boot(FAT32格式)和 root(ext4格式)。 2.1 查找TF卡设备名 将SD 读卡器插入 Linux PC 后,从dmesg或mount找到其设备名称。 $ dmesg |tail[19304.704047] usbcore: registered new interface driver uas ...
I am attempting to load a custom OS from SDcard. I have a SDCard boot loader that uses the IVT etc to initialise the dram, then load a kernel at 0x17800000 in dram. If I paste a linux kernel on the end of this it runs, so I know ram is set up and the kern...
I can't explain a permanent problem, a freshly programmed SD card should do the job. I remember one strange effect on the 8M board in the past: when the eMMc had a valid content from the boot image point of view, it always started from eMMC and not from an inserted SD card. B...
先将SD卡从开发板取出(开发板不要断电),通过读卡器插入 PC,复制一些文件到卡里,然后再重新插入开发板中 (SD卡拔出来时开发板不要断电,目的想测试一下 mmc rescan 命令作用)。SD卡拔掉之后,UBOOT一样可以运行,因为程序已经拷贝到DDR中运行了,只要不断电U-BOOT就可以正常运行。
