BL2根据是否存在BL31和BL32可选择性的加载不同firmware; 综上所述可知u-boot是一个运行在非安全世界的bootloader,负责加载各类操作系统,并提供丰富的驱动接口;并根据是否存在安全固件还可以进行不同的boot流程,如下。 u-boot,u-boot-spl,u-boot-tpl的关系:对于一般嵌入式而言只需要一个u-boot作为bootloader即可,...
第1个方法是通过SSH连接来将firmware放入到可写的文件系统,并且用命令将其刷人。 因为SSH支持文件的传输,用winscp+putty可以搞定。 第2个方法通过在电脑上搭建了一个http server,用ssh命令让openwrt从电脑上下载到firmware到板子上可写的文件系统, 并且用命令将其刷人。 第3个方法需要拆路由器,通过TTL线用命令让...
For most production firmware releases, addresses operated on (e.g. image loading locations) should either be fixed or obtained from cryptographically authenticated data (e.g. FIT images). Consider deviations from this guideline as potential red flags. [...] 我们可以看到它对配置提出了建议,因此不...

the first-level bootloader runs in OCRAM). It is used to initialize DDR and load U-Boot, U-Boot DTB, Arm trusted firmware, and TEE OS (optional) from the boot device into the memory. After SPL completes loading the images, it jumps to the Arm trusted firmware BL31 directly. The BL31...
