我这边基于MPC5744 做我们的Bootloader,目前需要将存一个Bootloader 解锁开锁标志到一个下电不丢失的位置。
在查找你们的数据手册的时候发现寄存器中CAN 的RXIMR 不受硬复位影响， 但是实际操作过程中只有软复位时候寄存器的值不丢失。
请问除了Pflash Dflash 之外还有什么位置可以做到掉电数据不丢失？
I do our Bootloader based on MPC5744. Now we need to save a Bootloader unlock and unlock mark to a position that will not be lost when powering off.
When I looked up your data manual, I found that the RXIMR of CAN in the register is not affected by hard reset, but in the actual operation, only the value of register is not lost during soft reset.
In addition to Pflash and Dflash, is there any other position that can prevent data loss during power failure
