[Solved]White screen of nothing again


#1

Just received my pokitto. Everything is fine so far but pokitto is stuck in some strange behavior, like some people seem to had before:
When i start the pokitto, it’s just showing a white screen. My situation:

  • Its NOT the display, demo worked
  • Win10

I tried out everything to get the loader installed, but the firmware.bin is coming back after reseting the pokitto.
Even the _copy.bat that was posted before can’t help. Is there anything I missed or I should try?

Possible problem: win 10 creators update, anniversary edition.

Do you have another comp to test?

Edit: another may be the usb cable


#3

Could you explain what happens when you plug it in in the flash mode?

FYI: I test every Pokitto twice before it ships but even then sometimes something goes wrong. All issues will be fixed


#4

It shows up as “CRP DISABLED” (or something like that). Than I delete the firmware.bin, and put the start.bin
(the one with the loader) on the pokitto. I tried out some other games bin’s but the result is always the same:
A white screen, no loader, no game and the firmware.bin is back. I tried to replace it also, with the same result.


#5

That does not mean anything. The ROM will always show a firmware.bin when connected in CRP_DISABLED (flash) mode


#6

Step by step:

  1. did you try another USB cable?

#7

Yes. Nothing changes


#8

Ok.

  1. if you paste the start.bin to the device and reset (with the cable attached to the PC), does CRP_DISABLED pop up by itself?

#9

No. But after resetting the Pokitto plays some randomly .snd data from the SD!?


#10

Ok.

Step 3. now that you have copied the start.bin to the device, and it is not popping automatically up as “CRP_DISABLED” we know some kind of a binary has been copied.

Now, put the Pokitto into flash mode (CRP_DISABLD), copy the firmware.bin and paste it here. I will cross check it with start.bin with a hex editor to see if the program is broken or not.

start.bin (256 KB)start.bin (256 KB)
EDIT: …


#12

Thanks. Back in a mo… wait. Did you copy this from the CRP_DISABLD drive? It should be called firmware.bin. Or did you rename it?


#13

start.bin (256 KB)
Thats the one I get from copying


#14

Comparing against the official start.bin, HxD editor says The chosen files are identical


#15

Ok. So this is good news, because it means your Pokitto is programming normally


#16

Step 4. The classic step.

Is your LCD connector absolutely, positively locked properly?


#17

It was the display. I feel stupid now. I was so sure it is connected as it should, meaby it was’nt locked on one side. Sorry for making trouble and thanks for helping @jonne, im happy now :blush:
