UART
« on: May 23, 2018, 10:21:28 am »
Hi all,

Does anyone know if there is access to a UART for a serial console on the Gemini PDA?

TWRP was ported so presumably there must be access somehow? (Or did TWRP just merge in MTK kernel patches and it worked?)

Cheers,

rah

I have to test it yet personally, but here is a photo of UART test points from Planet:

As for TWRP, it simply uses device-provided kernel sources, so it just worked, no special bring up needed (and it was already ported for other devices with similar SoC).

I see. I wonder if getting access to the mainboard will mean destroying the case?

I also wonder if Planet will be willing to send out some mainboards to developers, perhaps from returned stock that are only partly working or something?  Can I ask where the photo came from?  Does anyone here have contacts at Planet?

You need to use the gemini cover removal tool for the bigger of the two covers on the back of the display. afterwards, it's nine screws, three below stickers (that will be damaged while unscrewing).

I will try to post some pictures later.
