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

Instructions:

  1. gunzip u-boot_720p60piplus.bin.gz
  2. 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 ...)

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.

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

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