wrote a driver for gc2145 and configured/measured hsync/vsync polarity, and it only shows video on screen if I reverse the polarity on camera side compare to what would look proper
<karlp>
swiftgeek: that linux-serial-tests looks awesome
<karlp>
I've been looking for something like that for ages, and have three half started attempts at it myself
<karlp>
was always bothered by the apparent lack of proper test tools
<swiftgeek>
yup ^^
<karlp>
I'd always fallen back on sz/rz inside picocom to verify that things could perform properly with flow control and backpressure without corruption, but was't easy to script it.
<karlp>
so many of them assumed loopback, which is just garbage for testing IMO

karlp: now if that would be extend to work with two ports, i could even test different voltage levels or other stranger contraptions :D
<karlp>
swiftgeek: it aleady supports two ports....
<karlp>
otherwise I wouldn't have been so enthusiastic about it...
<swiftgeek>
oh but that involves RTS/CTS and i have only TX/RX :D
<karlp>
doesnt have to.
<karlp>
just don't put in the delay that would trigger it
<swiftgeek>
tried and it errors out at first, but then it somehow synchronizes i guess
<swiftgeek>
nope i added fault and it wasn't detected lol
<karlp>
well, I'll try it out some nex ttime I'm doing this crap again
<swiftgeek>
looks like it's fine if TX port starts sending frames before first "count for this session" appears
<swiftgeek>
or maybe i just found an issue with a chipie lol
<swiftgeek>
other chipie doesn't do that
<swiftgeek>
i lowered baud rate to 115200 and there is no such issue
<swiftgeek>
so fake CP2102 works fine even at 921600, but ch340g fails with 500000
<swiftgeek>
the highest stable baud rate for me is 230400 on ch340g ;D

how do you know it's fake anyway?
<karlp>
is ch340g even specced higher than 230k?

karlp: it's blank on the top + it doesn't quite match the spec i think

@karlp I have seen some python serial tests a while a go
<karlp>
if I hve to read 20 level indented python and all of the source anyway I can customize whatever I want
<zoobab>
it is a cli tool
<karlp>
doesn't do any comparisons and checking either
<swiftgeek>
just found fake ch340g lmfao
<karlp>
all that does is some randomly jittery transmitting and storing rx in a file.
<swiftgeek>
i know it's fake because it lacks markings and performs better xD
<swiftgeek>
package is different as well (still sop16)

Hi everyone! FreeBSD developer here, trying to add MMC HS200 support for the eMMC slot on Pine64. I can reliably communicate with the card at 150 Mhz, but at 200 MHz I get CRC errors sooner or later. I'd like to understand if sunxi-mmc driver really sets 200 MHz frequency when requested to do so
<uKibab>
Who can help me to debug this?
<anarsoul>
uKibab: likely you're not doing calibration
<mru>
the easiest way to find out what frequency it's using is to check with a scope
<uKibab>
anarsoul: there is the call to set a constant value in calibration register that both Linux and FreeBSD do. Is that what you mean or there is something more?
