hardware:nrf5340+npm1300
software:ncs 2.5.1
hi professor,
If I just connect VBUS, The npm1300 will reset when I read bulk register. If I connect vbat and vbus, read bulk register is normal.
ret = regulator_get_voltage(dev, ¤t_uv);
if (ret < 0) {
return ret;
}
The chip version i am using is CAAAC0.It was produced in May of 2024.So, it should not be caused by the following issue
[Errata 24] BUCK, CONTROL: Restart fails after reset with VBUS and VBAT connected.
My schematic design is as follows:I use an internal pull-up resistor in the CPU.
