Hi folks,
Maybe you could point me a way I could find any solution to solve issue.
Issue: no video output on hdmi connected monitor. First it shows no DVI input (I use DVI <> HDMI converter) then it blacks, seems signal is there now, but image still empty.
Workaround: I have preinstalled LInaro dist on nand, it work fine, I have clone it on SD card no problems too. As my desktop system is archlinux & I love this product & was up to install it according this guide (2 days ago) : http://archlinuxarm.org/platforms/armv7 ... er/pcduino
Seems bootloader & system ok, it loads as when I attempt in blind mode type root/root & pacman -Syu my net's led starts pulse & network work, when I type reboot or poweroff it shut downs - so system load & works correct, one issue it hasn't video output.
I started checking some workaround concerns with drivers & kernel modules:
I attempted according http://learn.linksprite.com/pcduino/a10 ... machine/to download hw_pack from pcduino git & copy modules to /usr/lib/modules dir
One note, at begin when kernel was first time installed there wasn't any monitor signal & my monitor displayed message - no input, when I added modules to load in /etc/modules-load.d/ (all modules that linaro has & that article too) lcd, hdmi, mali, mali_drm, disp & others, it started send signal but no image - only blank screen.
So then I back original modules from http://archlinuxarm.org/platforms/armv7 ... er/pcduino according compiled kernel
& it's still blank.
Then I was able to get image - I replaced kernel from this silte (latest) with linaro kernel, but my bootloader & rootfs are from archlinux's arm site, so - first there was tux on top of screen & the same blank screen, after system is loaded I had seen the login shell to archlinux, though kernel was from linaro I still was able to log in & with journalctl check logs, As I wrote there was my log about system upgrate - pacman -Syu & it was successfull, I check logs & it says all modules were loaded (hdmi, lcd, mali, mali_drm, disp)
So seems issue not related to hardware but to some kernel subsystem(module) or maybe it fails with DVI <>HDMI connector? But seems linaro able do it without any problems with arch rootfs
When I swap kernel back - the same issue - blank screen.
I will attemp to get log & attach from my sd card to post, though maybe you have any ideas what could be wrong?
Thanks in advance
