DRA821U: PADCONFIG initialized when migrating from SBL to app

Masaki Soga

Part Number: DRA821U
Other Parts Discussed in Thread: SYSCONFIG

I set the Sysconfig pin config with SBL and started the application.
I checked the PADCONFIG in my application and it was different from the value I set in SBL.
PADCONFIG not preserved when migrating application from SBL?
Is this as per spec?

Hi Masaki,

I don't think that Pinmux should change when jumping to the app.
At what point in the application are you checking the pinmux again? Is it going back to the default value or is it setting to something different?

Regards,
Parth

I checked PINMUX right after the application migration.
It was different from the value set in SBL.
I haven't checked everything, but it seems to be the default value.

I have not changed PINMUX in my application.
I have no plans to change it after setting PINMUX in SBL.

I'm sorry, I found the cause.
The cause was that the SDK sample "sciserver_testapp_freertos_mcu1_0_release" was registered as the startup app.
