Trying to configure GPIOs on "BLK18E-0012-38X38_S 50H10PE-S" board. It flashed without any issues (other than Ethernet needed some IOs enabled I guess, but that information was found.
I can do registry GPIO dump and there is no IR cut. Web interface has night mode disabled and no pins assigned.
So GPIO scan appeared to be the right tool. I can scan and see the report, but there is no explanation how it works and what to expect. There is a message: "waiting to toggle some IOs". I did toggle inputs to the IR Cut driver chip, expecting they are inputs on 3518 when unconfigured and I should see the change, but nothing happens.
I'm also concerned tat if IO is already output - it can be blown by external stimulus. Most IOs on HiSi chips are only 4 or 8mA.
Would be nice to have a bit more explanation about GPIO scan:
Does GPIO scan put all pins in HiZ? Maybe only unassigned/undeclared in registry?
-how long pin have to be stimulated to be registered as changed? is it instantaneous or slow and require full scan cycle? How long is it?
-as I have not seeing report of changed pins - some screen grabs would help. Unless it is so obvious.
web interface IO number format? Scan reports dual numbers separated by underscore. Is web interface takes the same format or it is remapped as linear numbers?
A little walk through use and operation of GPIO scan tool would be nice.
Best practice to scan and identify pins for IRcut, IRlight and SDC input?
How is "ipc tool/gpio scan"related to "gpio" app that I assume is independent app in default firmware. That one offered to scan toggle all pins or a (linear) range, so I assume it is not reading but driving, which is also can potentially blow some IOs.
I think whole community will benefit from these clarifications.
