Ubports edition shows nothing on screen after liquid exposure
Posted by: partytax - 07-14-2020, 05:12 PM - Forum: PinePhone Hardware
- Replies (5)
I've been using my PinePhone Ubports edition with much success for the last few weeks, but last night I think it was exposed to too much liquid. I laid out a bunch of things from my backpack and sprayed bleach cleaner over them (because the plague). After I dried things off, I tried to charge and boot my PinePhone (stupid, I know) and all I got to was a backlit black screen. The backlight turned on and off a few times pretty systematically. I typically use Mobian, but I tried booting into Ubports as well. Nothing...not even the Pine64 logo showed up. When I insert or remove the USB cable, however, the phone plays a clicking sound effect, which makes me think the thing might not be completely dead. Not sure if this matters, but the phone was in a pretty hot environment for the preceding hour and AFAIK had exhausted its battery when I cleaned it.
i2c0 transfers cause bus errors
Posted by: michaelanburaj - 07-14-2020, 02:25 PM - Forum: Linux on Rock64
- No Replies
Hello,the rock64 i2c-0 when trying to quick check discover connected devices (quick read, byte read, both), does send on occasions following the NACKed address byte a 2nd start condition and stop immediately, then another 3rd start before next transfer [see the attachment], that starts with the next device address. the additional 2nd start before the stop is bothering a STM32 slave sitting on this bus (additional data point a LPC controller does not get affected). While he STM32 seems sensitive to such errors (BERR) and causes lock-up, I am interested in knowing why does the rock64 do this. the bus is run at 100KHz, i even tried adding a delay in the loops for 100ms, still does not help. is there a setting in device tree or in rockchip's i2c registers to prevent this from happening? If this is not normal could some other hardware/software muxed on the port pins be causing this? [attachment: 1 NACKd-address in the capture is a normal one, that ends with a stop and the next start condition starts the next transfer. the 2nd NACKd-address ends with a added 2nd start, then stop, followed by a start for the next transfer] Thanks, -Michael.

A bit smaller?

I'm sorry if this subject was already discussed (I'm noob here), but was/is it even considered to build a smaller (version of) pinephone?
