[SOLVED] vga666 doesn't work with Raspbian Stretch Full/Lite

Wed Feb 13, 2019 6:21 pm

Hello, I have a Raspberry Pi Zero W an made me a Gert VGA 666 board. The wireing was double and triple checked. Same with the resistors. I have modyfied the config.txt

Code: Select all

dtoverlay=vga666
enable_dpi_lcd=1
display_default_lcd=1

#For 1024x768 60Hz
dpi_group=2
dpi_mode=16
spi and i2c are disabled.

But it won't work. No output on two different monitors. Is it possible that the support for vga666 are removed?

Thanks guys :)

EDIT: I did not checked the self soldered gpio pins for short circuited pins. Sorry guys :oops: :lol:

AFAIK, it should still work - however I'm not sure if I've updated/upgraded the version of Stretch on my test of a "clone board", as shown here: http://www.cpmspectrepi.uk/raspberry_pi ... A_Input.29 (My other, "original" VGA666 board was last tested with Jessie: http://www.cpmspectrepi.uk/raspberry_pi ... apter.html )
Can you remotely log in to the Pi and see what the tvservice -s reports? (Meanwhile I may have the time to update/upgrade & re-test)
Trev.
Still running Raspbian Jessie on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W) but Stretch on my 2xP3A+, P3B+, P3B, B+, A+ and a B2. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm

Sorry for the delay.

Code: Select all

[email protected]:~ $ tvservice -s
state 0x400000 [LCD], 1024x768 @ 0.00Hz, progressive

Only for completion I'm on a Raspberry Pi Zero W V1.1

I have to apoligize, Idiscovered a solder blob on the backside of the pi that short circuited the v-sync and h-sync pins :oops:

So, everything works fine now :lol:
