I am using ATSAMA5D36 xpained board, I tried to mount RTC battery (CR1220) coin cell in the VBAT pin of J14 header
But the battery voltage is draining from 3V to 1V with in a day
What will be the reason, can anybody help me to solve this,
Please find the attachment,
As my understanding, The battery voltage drop due to the R185, But
I removed the R185 (1.5K) resistor also even though its doping.
