Hi Expert,

Custom board can not detect that pmic output voltage.

Could TPS65910 work if AM3352 is not flashed image?

BOOT1=1 , BOOT0=0, PWRON floating

Thanks

Hi, Daniel,

Please do followings:

AM3352 should be flashed with correct image before power on the PMIC.
PWRON should be pull high to VBAT through a 10K Ohm resistor.
The processor AM3352 should drive PWRHOLD pin high for powering on the PMIC.
Please read through the document "TPS65910Ax User's Guide for AM335x Processors" for more details.

Please let's know if you still not detect output from the PMIC after above being set properly.
