可重复烧写 bootloader 模式下,secure bootloader key 是在 PC 端产生的,此 key 必须保密,一旦 key 被泄露,其它使用此 key 生成digest 的 bootloader image 也能通过硬件检查 使用步骤: 1.make menuconfig 中选择 “secure bootloader mode”->“Reflashable” 2.按“使用步骤”一节步骤2和3生成公钥与秘钥 3.运...

此时,启动 SPI 驱动,并加载 Flash 中的程序段。ROM 会读取外置 Flash 的 0x1000 地址,加载并运行二级 bootloader。 [关于 Bootloader] bootloader 可以认为是一个独立的小程序,bootloader 会对芯片频率进行初始化,并且读取系统 SPI 的配置信息,对 Flash 运行模式以及频率进行配置,然后根据分区表的定义,从对应的地址...
1.make menuconfig 中选择 “secure bootloader mode”->”Reflashable” 2.按“使用步骤”一节步骤2和3生成公钥与秘钥 3.运行指令 “make bootloader” ,一个 256-bit secure boot key 会根据用于签名的私钥计算出,命令行会打印两个后续步骤,按循序执行: 将PC 端生成的 secure boot key 烧入 efuse 中的...

I have some trouble to reflash the ESP32S3 after activating the USB-CDC (tinyUSB). So basically the only option at the moment is to press the button to go into the bootloader mode at startup to reflash the device. Now assume I have the device connected to a SBC in the field and ...
