Hi Clement and Chen-Yu Tsai,
this time we send the kernel logs as requested, but before that here are our
findings. We have inspected the LCD TFT panel and although it is from Olimex it
is not compatible with the "olimex,lcd-olinuxino" simple panel driver. It has the
very same board but the eeprom ic is not present, this time we checked the I2C
tracks and the olimex documentation. It seems that only some models have this
eeprom installed, and the driver needs this to autodetect the panel model. Also
we would like to use diferent panels in the future, so declaring the panel in the
I2C bus is not an option.
We make some changes to the device tree, as Chen-Yu Tsai suggested the panel
should be declared as a panel-dpi (with timings, backlight, power, etc) Below these
lines you could check our complete device tree. This time nothing happens, in the
kernel logs no sun4i-drm driver messages... but, as we have been trying many many
combinations without luck, when we disable this panel (status "okay" -> "disabled")
then in the kernel logs some sun4i-drm driver messages appear (at last!) some of
them complaining about the frontend and the non existence of panel. By the way,
until now we could see on the panel only thanks to the uboot configuration:
CONFIG_VIDEO_LCD_MODE="x:1024,y:600,depth:18,pclk_khz:45000,le:150,ri:16,up:21,lo:2,hs:10,vs:2,sync:3,vmode:0"
CONFIG_VIDEO_LCD_POWER="PB10"
CONFIG_VIDEO_LCD_BL_PWM="PB2"
but when we disable the panel on device tree then the panel turns off as linux boot.
Here comes the device tree [1], the kernel logs [2] (no changes) and the messages
that appear when we disable the panel [3] (from the sun4i-drm driver) Note: Don't
take into account other messages regarding the lost of entropy... as we also have
problems with cryptodevice and rng-tools (sunxi crypto) and that is another story.
Thanks again for your help and excuse our ignorance :-)
Best Regards,
Sergio Sota
