Blank screen after flashing - system doesn't work

[Artur2048]

Right after installing RetroESP32 on my Odroid GO the screen goes blank and system doesn't respond to any buttons. Restarting device and trying various button combinations (like holding menu while powering on) didn't helped.

I have the latest Odroid-GO firmware: Ver 20181001:
https://github.com/OtherCrashOverride/odroid-go-firmware/releases/tag/20181001

I'm using the latest RetroESP32 release V2.6:
https://github.com/retro-esp32/RetroESP32/releases/download/v.2.6-Recent-Favorite-Fix/odroid-go.zip

Steps to reproduce the behavior:

1. download odroid-go.zip (v2.6 of RetroESP)
2. put "Retro ESP32.fw" in odroid/firmware folder on the SD card
3. hold B button while powering on Odroid GO
4. choose ESP firmware, click A, then START to confirm

Verification, Erasing and flashing starts - in total 8 cycles of erase/write.
At the end screen goes blank.

(device works perfectly fine on the original "GO-Play v. 20181004")

Hmm, I just tested on mine and was unable to reproduce

Shut off the device
Hold B
Turn device on still holding B
It will restore to Odroid Firmware

Hello, Thank you for your response, Yes. I know about "B" - power combination. It of course works and let's me reflash my device again and again. No problem. I have tried few times to flash RetroESP32 without success. I've made a video: https://www.dropbox.com/s/chc63w7sroqttfb/20201011_202513_1_1.mp4?dl=0 Best​ ​regards, -Artur

Hi!

Just FYI I got mi Odroid Go yesterday in the mail and I'm having the exact same issue as you. If you can resolve the issue please let us know Arthur. Thanks!

[Artur2048]

Hello, Unfortunately I wasn't able to get it working. Let's compare our hardware, maybe it's related to particular board version. I have: "10th anniversary, rev 0.1 20180807". Best Regards, -Artur

This bug its only on boards witch 8Mb PSRAM

[bodobear]

Hi,
I just tried to install the actual version and it´s also not working ony my new odroid go.
got the same revision like Artur mentioned before. "10th anniversary, rev 0.1 20180807"
Using the multi bootloader and also retro-Go. everything is working fine but not RetroESP32.
Have another old Retroid Go Model.. no problems on that one so it has to be the newer/different board.
Any plans or infos about a fix for that issue ?
Thank you... Bodo

Redoing this post with some more information:
It seems the firmware has an issue with allocating external SPI RAM on the "REV 0.1 20180807" ODROID-GO. It continuously tries to reboot itself after running into this error, resulting in a blank screen:

[usepinlove]

I have the same problem...
Is there any solution?

[Artur2048]

I haven't found any solution anywhere. It seems to be a bug in RetroESP32 that shows up only on certain Odroid-go boards (probably the most recent ones) -Artur

[stl1988]

Same here. Rev 20180807 and black screen with the same externam RAM to heap error.

[32teeth]

Correct, this is if you are on the old firmware.
There is a great article here https://medium.com/@siloraptor/upgrading-the-firmware-of-the-odroid-go-dd7eebdc7ed4

I am working on the base firmware as well

[stl1988]

That link is not related to RetroESP32. Go-Play is not affected by that black screen issue.
