HDMI->VGA screen stopped working

Hi,

I accidentally replaced my script.bin by the default one.
It probably caused that my quite old monitor connected via HDMI -> VGA converter stopped working (it remains in standby mode).
Unfortunatelly I'm not able to restore previous settings in scritp.fex

Here is my actual disp_init section:
  1. [disp_init]
  2. disp_init_enable = 1
  3. disp_mode = 0
  4. screen0_output_type = 3
  5. screen0_output_mode = 5
  6. screen1_output_type = 2
  7. screen1_output_mode = 11
  8. fb0_framebuffer_num = 2
  9. fb0_format = 10
  10. fb0_pixel_sequence = 0
  11. fb0_scaler_mode_enable = 1
  12. fb1_framebuffer_num = 2
  13. fb1_format = 10
  14. fb1_pixel_sequence = 0
  15. fb1_scaler_mode_enable = 0
Copy the Code
and boot.cmd excerpt:

  1. setenv bootargs console=ttyS0,115200 console=tty0 console=tty1 sunxi_g2d_mem_reserve=0 sunxi_ve_mem_reserve=0 hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1680x1050p60 root=/dev/sda1 rootfstype=ext4 elevator=deadline rootwait
  2. setenv bootm_boot_mode sec
  3. load mmc 0:1 0x43000000 script.bin
  4. load mmc 0:1 0x48000000 uImage
  5. bootm 0x48000000
Copy the Code


So far I checked:
- VGA converter on other source - works OK
- other monitors, even FHD -  they also don't work
- various screen0_output_modes - monitor doesn't work
- various disp.screen0_output_modes - monitor doesn't work
- with and without EDID - monitor doesn't work
- HDMI - HDMI output - monitor works OK
- various Power Supplies 2A, 3A and so on - monitor doesn't work

I have no idea what else I can check.
Any help will be appreciated...

Ok, finally found the reason:

All things which need more current don't work but what is interesting - banana still works stable, even with 2,5" SATA connected (powered from banana).
Pure HDMI also works.

Doesn't work:
- GPIOs (5V is currently ~ 1,5V)  but 3V3 seems to be stable
- VGA converter
- USB devices
