RTC[edit | edit source]
Description[edit | edit source]
MITO 8M Mini/Nano Evaluation Kit uses the RTC device provided by MITO 8M Nano PMIC
An external lithium battery (like Panasonic ML-2020/G1AN rechargeable battery) can be optionally mounted on SBCX.
Signals[edit | edit source]
The following table describes the interface signals:
| Pin# | SOM Pin# | Pin name | Pin function | Pin Notes |
|---|---|---|---|---|
| - | J10.14 | PMIC_LICELL | coin cell battery network has to be properly configured for lithium battery recharge current |
Device mapping[edit | edit source]
RTC is mapped to /dev/rtc0 device in Linux.
Device usage[edit | edit source]
The peripheral can be accessed through the date and hwclock linux commands.
