TDA2P-ACD: SoC Sleep mode realization

ALWIN MATHEW K SUNNY

Part Number: TDA2P-ACD
Other Parts Discussed in Thread: TDA2

Hello,

We are using TDA2Px in our project, we are facing some issues related to boot time optimization and sleep mode implementation with TDA2Px.

We need to implement a sleep mode with TDA2Px and need to wake up the SoC using CAN signals. Is this possible for power better power management.

Is there any readily available solution for this kind of implementation?

The second thing is like we need to optimize the boot time to 4 seconds using Linux, Could you please suggest a way to optimize the boot time.

And also please help with a readily available solution?

Warm regards,

Alwin Mathew

Hi Alwin,

1) No such implementation is available. It depends on what and how you want to implement. We only support
dynamic power management:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/Kernel/Kernel_Drivers/Power_Management.html

i believe you are looking at idle low power modes which are not supported.

2) http://www.ti.com/lit/an/sprac82/sprac82.pdf Describes multiple steps to optimize boot time optimization
on DRA7/TDA2 devices.

Keerthy
