Part Number: AM62A7
Tool/software:
Hello, Sreenivasa.
I make a new thread about VPP enable control by MPU.
You mentioned through Jack Cha that you can help the implementation for VPP control by made a thread on E2E.
VPP_EN signal is connected to GPIO9 of the PMIC(TPS6593) through IO expander.
However, I do not need to use IO expander for my design.
So, do I just connect any GPIO pin of the MPU to GPIO9?
If that is correct, I wonder how to make AM62A7 control its GPIO.
In according to the section 7.10.2.2.1 Power-up Sequencing in datasheet, VPP should be ON after most system is supplied.
And I think the SW code is contained in EVM SDK.
Simply asking,
Q1. Any GPIO of MPU is directly routed to PMIC GPIO9 under the condition IO expander not using in the design, is it right?
Q2. Could you let me know where I can find the code to modify need to change GPIO pin setting?
Let me know if there is any error in my question.
For the more, I also want to be ensured that GPIO9 connection is the solution with no need to design or modify to hardware or software in PMIC side.
Regard
