STMP1 / Re: STMP157 + EVB Backup?

Last post by LubOlimex - May 31, 2024, 01:22:43 PM

Which board exactly do you have? We have STMP157-SOM and STMP157-BASE-SOM...

Re-write the card with the latest official image and try again? Refer to the Olimage guide here:

STMP1 / STMP157 + EVB Backup?

Last post by bobart - May 31, 2024, 10:38:37 AM

Hi,
I have cut the first boot; the installation of the olimage... I didn't know that it corrupt the board...
Now I can't install the olimage on my STMP157 with his evb socket... I have a ttyUSB0 which appear, I can connect to this port, I do it  with screen software, and  I see just an underscore which toggle without keyboard acces...?
I tried to do a backup with connected the backup pin with the closest pin... No way.

Thanks for your help.
PS: I haven't find the category to pôst about the RT1010py ucontroller?

Dear Lubolimex from Olimex, has there been any updates regarding this topic? i have used a diffrent poe board from another supplier which solved the issue, however i really like the Olimex boards and would love to use for simmulair applications, which isnt an option unfortunatly.

with kind regards,

Kornei

No. We only have A20 designs with up to 1GB of RAM. We have A64 design with 2GB RAM, namely:

A64-OLinuXino-2Ge16G-IND
A64-OLinuXino-2Ge8G-IND

A20 / Olimex A20 SoM with 2GB RAM

Last post by Madhu Gaddam - May 28, 2024, 07:24:57 PM

Right now we are using the Olimex A20 SOM (i.e A20-SOM-n8GB )  with 1GB DDR memory. But we want to add new features to our product, which requires min 2GB DDR.

Does the Olimex has any 2GB A20 SoM variant? Quick help is required for this?

Did you check the polarity? One of the common mistakes is using an incompatible with the board battery (with reversed + and - on the connector)? "-" and "+" pins are marked below the connector on the top side.

If you've connected battery with reverse polarity it might have damaged the battery circuit.

Edit: I also checked the manufacturing procedures, there is empirical battery test that each board has to pass.

You can empirically confirm it is working. There are two ways:

1. Easier software but requires some additional hardware - Connect a LED with resistor between a free GPIO and GND, then download code for blinking LED to that GPIO. You can use breadboard and jumper wires.

2. Harder software but doesn't require anything additional - Without anything additional download some WIFI code that allows you to access or ping the board over the WIFI network. Like WIFI server. First confirm it is working over the USB. Then remove the USB and from another device in the same network confirm the connection (or even via the router's panel confirm the IP address associated with the board is still there).

Thanks for sharing. The important part about PoE2 is that it uses ESP32-WROVER chip instead of ESP32-WROOM. Which leads to different Ethernet clock pin compared to ESP32-POE.
