I have a couple questions regarding the Sudden Power Loss condition for the NX Module. Our application is battery powered, so there is a risk that the user could pull the battery and trigger a sudden power loss event.
In all of these scenarios, we can assume this timing requirement from the Nvidia documentation is satisified:
- What does the the NX do during that 10ms hold-up time? Does it protect the EMMC against corruption due to power loss?
- Do we need to ensure we don’t write to the EMMC filesystem during a power loss?
- Is there risk to an attached SD card getting damaged during this power loss?
- Do we need to ensure we are not writing to the SD card, or should we attempt to unmount and disable the power to the SD card prior to a sudden power loss?
Thank you,
