Beaglebone Black AC powered failed problem

Hi Amon,

This is not normal. What is the AC supply that you use?

Hi Biser,

Yes,I know it is not normal. It is a normal supply named ZHAOXIN DC power supply TXN-1502D,

the other is named ZHAOXIN DC power supply PS-3005D.

and we have a Youhong AC Adapter which input AC 100-240V 50/60HZ, output DC5V 2A.

Actually, these power supplys we used on other EVB we developed before work OK.

the correct log under USB cable connected to PC for you information.

Another thing to check is whether you have a good GND connection between BBB and PC when powering from external adapter.

Hi, Biser,

 we have verified that maybe not for GND.

Is it possible we use a wrong check method? If you have some good ideal, please help me.

Thank you very much

We have tested that the PGOOD works ok when using AC adapter.

Hi,Biser,

we check the question again, and connect  a good GND from an oscilloscope GND to the big whole near P8 or P9 with the AC power on. It looks good.

But we find there also has wrong log such as follows:

1,What is the possible problem?

2,also is related to not good GND?How can I do next to check?

Please help us to clarify the phenomenon.

Another question is how we can get a solution like just connect AC to power on the BBB?

What should we consider in Layout PCB?

The BBB design files can be found here: http://elinux.org/Beagleboard:BeagleBoneBlack#Hardware_Files

Yes, you can connect only AC power to the TPS65217. Please refer to documentation on the PMIC product page:
