求助各位老师,DM8168的1V0_avs电压的问题,不同的CPU型号有不同的初始电压?程序和硬件都需要修改?相信这个问题大家都还没遇到过。

Other Parts Discussed in Thread: TPS40400

我在8168的datasheet上看到了这个表格。

然后,还有下面这些话。

The initial CVDD voltage at power on must be 1.00V nominal (for CYGA2 and CYG4 devices) or 1.10V nominal (for CYG and CYG2
devices) and it must transition to the AVS target value adjusted by a AVS driver. This is required to maintain full power functionality and
reliability targets specified by TI.

我们的CPU具体型号是TMS320DM8168SCYG。

目前的程序是针对初始电压是1V0的。请问应该怎么修改?

我是不是应该首先在硬件上修改,通过更改Rtop和Rbottom把TPS40400的初始电压改为1.1V。

然后软件需要修改什么?只修改pmic->nominal_uV行吗?GPIO voltage regulator应该用不到了吧?

望各位讨论解答,谢谢。
