Gemini PDA - Hardware / Spilled some water, now touchscreen and keyboard problems.

« on: February 09, 2020, 04:01:25 pm »

Was a bit slow with drying / shaking out water. More and more keys started to behave strangely, until the device went into an infinite boot sequence.
At home I removed all keys, but there really wasn't much to dry.

Several hours later, the device booted normally. Unfortunately, some keys have ceased working (q, a, 4, 6, right arrow and enter).
When I press one of them, nothing happens. Strangely enough, pressing a working key after that, does not work once or twice, but then works normally.

As far as I can see, no damage to the keyboard electronic foil (that thin layer immediately below the rubber mat); chances are the point where the connector(?) is, top right of the kbd, got wet.

Worse; when swiping over the touchscreen, I still trigger an infinite boot loop (yikes! not even sure how that is possible! when the boot sequence otherwise seems normal)

Any insights helpful....

Gemini PDA - Android / Compiling Oreo kernel for rooted WIFi model

« on: July 07, 2019, 06:31:41 am »

On Android 7, I think non-rooted, I had this working

Did a `git fetch` on https://github.com/dguidipc/gemini-android-kernel-3.18
Checked out the Gemini_WIFI branch
did a `make oldconfig` which had two questions only.

Repacking and flashing `root_boot.img` so far resulted in an infinite boot loop.

What I do not know:
 - Where is the Planets `.config` for Oreo? I may be starting from a non-bootable starting point and fail forever
 - There is an ID in the boot configuration, but `abootimg` is not meant to set it to the value that Planets put in. I have no idea whether this is relevant.
 - How is my image "rooted"? Is that something in the kernel? ramdisk? other partition?

Gemini PDA - Hardware / Gemini as Keyboard

After some work, I can use my Gemini as if it were a USB keyboard.
