Try to write the attached "new" u-boot on SD-card.

Instructions:

gunzip u-boot_720p60piplus.bin.gz
sudo dd if=u-boot_720p60piplus.bin of=/dev/sdX bs=1k seek=16400

Copy code

give response if OK
ciao

PS. instead of the sdX you need to use your device for sdcard (sdb, sdc ...)

same problem.. the screen continuo to go black and I need to turn off and on it..

between the orange hdmi and my screen there is a hdmi-vga that works with raspberry1-2 and a banana pi.. So I think that it is not the problem

@piento
Have you tried if HDMI out works on TV or other HDMI IN device?
Have you tried with android?
maybe changing resolution on TV and then connect with converter to your VGA-monitor.

with android is ok!
but however the resolution is the same like before i "dd" your uboot image...

For the "same" you mean 720p50?
if yes, can you post the exact commands you have used to write with "dd"?

when i "burn the img":
dd if="lubuntu.img" of=/dev/sdb
when i burn uboot

sudo dd if=u-boot_720p60piplus.bin of=/dev/sdX bs=1k seek=16400

/dev/sdX does not exist!
X is only a "placeholder". For you it's /dev/sdb for me it's /dev/sdc for other maybe /dev/sdd.
Hai capito?

in your case you need to write with command:

sudo dd if=u-boot_720p60piplus.bin of=/dev/sdb bs=1k seek=16400

Copy code

Try

I know. I made a mistake when I "rewrite" in the post the "code" that I have written..
(I simply copy and paste your code).
I know that X meands a, b, or d...
