BOR event every 8 seconds
Hi Dialog,
we developed a custom board for the DA14680 and experience a BOD reset every 8 seconds.
The BOR only occurs with DCDC on.
在BOR事件CRG_TOP - > BOD_STATUS_REG Register reads the Decimal value 19, sometimes 21. It indicates a problem with the 1V8 or 1V8P rail, but I can not find the cause.
The DA14680 is in a aQFN-60 package.
Additionally we use a slightly modified version of the ble_peripheral example and the lates SDK (SDK_1.0.14.1081)
