Odroid Go not working (spiram: SPI SRAM memory test fail)

[ElTentakel]

Hi, i've reveived my unit today, assembled it and made a first test - everything worked (I got the missing roms symbol). Then I copied the skeleton and a gbc rom file to a 4GB SD Card and inserted it. After turning on the machine, the display stays white. I tried the menu trick and reflashed the Firmware - same thing.

Then i just plotted the serial output and it throws the following error on boot:

Is my device broken?

I tried to upload the latest Firmware with this method:

viewtopic.php?f=158&t=31513

First thing: Now I know, that the display works, but it cancelled with an sdcard block error after starting the flash of firmware.img. I will try another SD Card.

OK, tried three SD Cards, last one worked. But I get still the SRAM Error. Is my PSRAM broken?

We will check when/how the failure error message appears since this is the first time I've ever seen.

[crashoverride]

The PSRAM test is part of the esp-idf. Since PSRAM is self contained inside the WROVER module, it indicates an issue with the module.

[odroid]

@crashoverride,
Well noted.

@ElTentakel,
You have a hardware issue.
Please contact "odroid at hardkernel dot com" with a link of my post.
She will help your RMA process if you purchased the board from us directly.
Otherwise, contact your local distributor.

[ElTentakel]

Hi, i have no idea why, but on Friday morning after flashing, everything was fine. I changed nothing.

Maybe the wroover has a bad cold solder joint. But I was to excited to play with the go, so I will report back if I have any issues again.

[odroid]

Glad to hear it works now even though it is weird.

Once you meet a similar issue again, please let me know.
