Hey I'm currently trying to boot my bpi-m3 with hdmi display, but it is not working and the wiki seems to be outdated. These are the boot arguments: console=tty0 console=ttyS0,115200 root=/dev/mmcblk0p1 rw rootwait panic=10 hdmi.audio=EDID:0 disp.screen0_output_mode=1920x1080p60 consoleblank=0
<embed-3d>
Has anyone an idea what I'm missing?
<aep>
is the i2c speed on the h2+ fixed? i cant find anything to configure it
<anarsoul|2>
aep: try changing it in dts?
<aep>
nothing in /sys/firmware/devicetree/base/soc/i2c@01c2b000/ at least, so maybe the dts either doesnt specify it because the default is fine, or you cant
<[TheBug]>
Anyone have a good/known working (with ethernet) DTB/DTS for pcDuino3 nano for mainline -- the Armbian version seems to be incorrect and breaks the Gmac and causes it to give weird errors. If I try to load the board with the BPi M1+ DTB, the Gmac comes up, kernel driver looks to load, but like 20% packet loss and you can't actually establish any connections --
<[TheBug]>
trying to figure out if it is caused by DTB settings or something in uboot
<aep>
[TheBug]: isnt there one in mainline?
<aep>
arch/arm/dts/sun7i-a20-pcduino3-nano.dts
<[TheBug]>
again, assuming its the one Armbian is pulling its not working -- but happy to grab what you link and test it to see if its different
<aep>
no thats openwrt
<[TheBug]>
using sun7i-a20-pcduino3-nano.dtb
<[TheBug]>
that is provded by Armbian with pcDuino board image
<aep>
willmore:400khbits but apparantly clock-frequency = <400000> just worked thanks :)
<willmore>
I don't know the driver, so I don't know how conformant it demands to be. I know some I2C interfaces are really strict about only clocking at 100KHz or 400KHz.
<aep>
yeah, it was happy with 400. dont need anything else

i have the console and earlyprintk bits in boot.cmd
<andy25225>
but what i don't have is all te correct options in "Kernel hacking"
<andy25225>
thanks for the pointers

<andy25225>
now if i enbale these options, then run make again for the zImage... do i have to rebuild the modules too?
<megi>
I always rebuild modules, not sure if it's necessary
<megi>
probably depends on kernel config around module versioning
<megi>
they'll usually rebuild quickly anyway
<andy25225>
ok... i'll rebuild them to rule out latter confusions
<megi>
I once ended up with issues because modules were built for "v123" and kernel was built for "v123-dirty" (when building from git tree, if it's dirty this is reflected in the kernel version)
<megi>
and the modules would not load :)

i haven't opted for a git version.... I'm using 5.4.32, as that is what slackware-current is using
