Hiroyasu Tazawa1

Hi, Everyone

I have a question.
SDASR_EN1/2, INT, SLEEP signal and AM335x are connected
on SWCU093D(TPS65910Ax User's Guide for AM335x).
but There are not connected on ICE board of AM335x.

Do you know why it is difference ?

Hi,

Recommendation is to connect SCLSR_EN1 in parallel to SCL_SCK, and SDASR_EN2 in parallel to SDA_SDI. INT and SLEEP can be left unconnected. This is how it's done on all AM335x EVMs.

Hi, Biser

Thank you for your reply.
I wanna make sure why SDASR_EN1/2 is not connected ?
Because you recomend SDASR_EN1/2 is connected.

These are needed for Smart Reflex support. Currently this is not supported in the AM335x software, but this may change in the future.
