二、在MIMXRT685-EVK上实践 我们现在在官方 MIMXRT685-EVK 上实测一下这个功能,EVK 上选用的 Flash 型号是旺宏的 MX25UM51345G,这颗 Flash 有独立的 RESET# 引脚(A4),它被连到了主芯片的 PIO2_12 脚上。 要想激活 BootROM 中 Flash 硬复位功能需要烧写 eFuse(也可以写相应 OCOTP Shadow Register 来...

有必要对如下使用Fixed Otpmk(SNVS) Key加密的BEE参数设置页面再做一下介绍,主要是设置Region Count以及指定Region范围,默认为0即自动对整个image区域进行加密。 一切操作无误,板子上SW7拨码开关将Boot Mode设为2'b10即Internal Boot模式,并且将BT_CFG[1]设为1'b1(使能Encrypted XIP),其余保持全0,重新上电便可...
