Hi ,

I have same issue in TPS65987 ,

When I set 20V 3A profile to 20V 5A. by Source Board(TIDA-050012) with pjt(TIDA-050012 Source Board)

Then using Sink Board(TIDA-050014) to Check Source Profile with "Received Source Capabilities(0X30)",

But the Receive Source Profile still show 20V/3A , Can help me please?

(-----------My Device--------------)

Source Board: TIDA-050012
Sink Board: TIDA-050014
Type C Cable: E-Books

TPS65981_2_6_7_8 Application Customization GUI Version : 6.1.1

Source Board Pjt File:

(1) When I connect other type-c charger witch can provide more than 3A to Sink board, then Check the register "Received Source Capabilities(0X30)", it's profile is correct as Type-C Charger .

(2) Is there any register in TPS65987 that can check E-mark is on or not?

Hello,

When you program the boards, are you power cycling afterwards? If not, please make sure to do this step as the new configurations will be not loaded until it is powered off and on again.

For the E-Mark check, you may need a PD analyzer such as one from Total Phase so that you may look at the PD log with the Discover Identity message.

Thank you,

Hari

Dear Hari,

(1) I already try to re-pluging the type-c cable after setting new configurations.

(2) Sadly, i don't have PD analyzer. Can you help provider TIDA-050012 Prj witch can support e-mark to set 20V/5A .

Hi ,

I check the Last Post , It say recommended to attach 5V to the PP_Cable pin. For VCONN provide power to e-marked Type-C cables.

Now I use Source Board is TIDA-050012, It seems connect PP_Cable pin to Ground,

If want to use e-mark need re-work on TIDA-050012 connect PP_Cable pin attach 5V?

Hi Les,

Yes unfortunately, if you plan to provide VCONN support via PP_CABLE, then yes you will have to either use another EVM board or rework the TDA-050012 so that it is connected to 5V.

Thank you,

Hari
