<lvella>
but the previously installed kernel was starded instead
<lvella>
so I believe u-boot is ignoring /boot/boot.cmd
<lvella>
where does uboot looks for the configuration file?
<wens>
if you have console access to your u-boot
<wens>
you can run "printenv", and look for bootcmd and trace it from there
<lvella>
I tried, but I didn't manage to get a serial terminal with the device

lvella: sounds like you are using stock u-boot?
<lvella>
yes, I didn't try to build or flash an u-boot different from what comes in armbian distro for orange pi zero
<lvella>
but I figured the file it looks for is boot.src
<MoeIcenowy>
I think armbian uses mainline u-boot
<MoeIcenowy>
wens: stock u-boot is not so smart ;-)
<lvella>
well, it understands ext-4, so...
<wens>
armbian might have tweaked the config a bit
<wens>
I've never used it though

MoeIcenowy: Hi, thanks for the report! I'll test on an A33 as soon as I can and let you know. Your fix is a hack indeed and shouldn't make it to mainline since 0 (even as improbable as it is) is a reading within valid ranges so we cannot say that 0 is invalid.

take the parts in sun4i_gpadc_probe_mfd and sun4i_gpadc_probe_dt registering the device (or parent device) out of their respective functions and put them at the end of the driver probe function

kever has joined #linux-sunxi
<MoeIcenowy>
qschulz: oh... the same problem
<MoeIcenowy>
can you add traces to runtime_{suspend,resume} functions and read_temp function and verify that their execution sequence?
<qschulz>
MoeIcenowy: I sure can
<MoeIcenowy>
for me the runtime_resume function finished after regmap_read, which shouldn't happen -- I think pm_runtime_get_sync should return after runtime_resume finish
f0xx has quit [Ping timeout: 248 seconds]
<MoeIcenowy>
and so when executing regmap_read the THS is not yet ready
rexxster has joined #linux-sunxi
<qschulz>
MoeIcenowy: hum... from the code, the expected sequence is read temp, get_sync so it's wrong
<MoeIcenowy>
what?
<qschulz>
I can verify but I'm convinced it's how it is done
<MoeIcenowy>
is get_sync blocked?
<MoeIcenowy>
but when the system is fully booted the read sequence is OK
kever has quit [Ping timeout: 255 seconds]
<qschulz>
look at the probe function
<MoeIcenowy>
still cannot get it...
kever has joined #linux-sunxi

<MoeIcenowy>
qschulz: yes
<MoeIcenowy>
it's the issue
<MoeIcenowy>
but the problem that it will hit the critical trip point only exists on H3
aidin has joined #linux-sunxi
<MoeIcenowy>
as H3 have negative scale
<MoeIcenowy>
so 0 will mean a high temperature (216 C)
<MoeIcenowy>
A33 have positive scale and 0 will mean a low temperature
<qschulz>
MoeIcenowy: thx for confirming. Even if it does not break the A33, it's definitely wrong. I'll make a patch and send it in the upcoming days.
<qschulz>
and i'll have a look at that requirement for thermal-zones as well. Thank you for reporting those bugs :)

P.S. for boards with SY8113B I now suggest that U-Boot init it to 960MHz and set voltage to 1.1V
aidin has quit [Ping timeout: 260 seconds]
<MoeIcenowy>
when debugging the THS driver, I found that 1008MHz@1.3V can easily get the SoC to 100 C on Orange Pi Zero
<MoeIcenowy>
but 960MHz@1.1V can keep to 80 C
