Lets say i have a raspberry pi attached to a spi oled screen. life is good , i can display nice text and graphics after boot...

But , i wonder , is possible to display an splash image during boot? or display the console output during boot ??

  • I have an RPi attached to an SPI LCD screen, and it starts displaying console text somewhere in the middle of the boot process; probably as soon as the driver is initialized. Do you have a Linux driver for the display? Do you think console output at 128x64 pixels would be useful? – JimmyB Oct 25 '16 at 10:21
  • I doubt this works as a normal display like the LCDs do, would be part of the issue here. It is unlikely to receive an answer without further information about the way the screen behaves and is used. – goldilocks Oct 25 '16 at 12:38
  • @JimmyB My apologies! Missed that. – goldilocks Oct 25 '16 at 14:02

    Apparently, my other comment was deleted when the question was migrated. I suggested to search for "framebuffer" in conjunction with SSD1306, which I assume is the driver chip of the display. See e.g. raspberrypi.stackexchange.com/questions/28813/…. – JimmyB Oct 25 '16 at 14:02
  • That thing doesn't necessarily have any (display related) kernel driver at all, which is why I've said more information is needed (I won't actually close the question now because there is no point in bouncing the migration). It could be entirely controlled with userland software, the only kernel level stuff is the generic SPI interface. – goldilocks Oct 25 '16 at 14:03
