MPC5744P

Here's the English translation of your question: > Why is it that when I modify certain register values of the MPC5744P through S32DS, only some of the embsys registers can be modified? When modifying certain RW register values, an error is reported: "Error: Error in ONCE status register during instruction execution."

为什么我通过S32DS去修改MOC5744P的某些寄存器的值也是只有部分的embsys registers寄存器能被修改。修改某些RW寄存器值时会报出Error : Error in ONCE status register during instruction execution？
将上述一段话翻译为英文

Re: MPC5744P

Hello,

Without knowing any details I will answer just generally:

The error is NOT a register access error - It is a debug link failure triggered by your write
And that happens because those specific registers:

cause reset
are not accessible in current mode
require unlock / clock / sequence
or cannot be safely written via debugger

Best regards,

Peter
