A20 / Re: A20-SOM REV D wrong board ...

Last post by LubOlimex - December 01, 2023, 08:42:16 AM

However due to the age of the image it seems I cannot update most of the packages.

Just set the date manually first. Use "date" like:

date -s "1 DEC 2023 10:00:00"

To set the date to 1st of December.

A64 / Re: Compiling kernel modules

Just realized that there is a guide for this at the end of the Olimage-guide document!

Comparing what I did with those instructions, seems I was missing the

Code Select Expand

DTC_FLAGS=-@flag in my make command.
Will try and confirm here if it works.

STMP1 / Re: Schematics not opening in ...

I believe this can be some issue with your KiCAD installation - try reinstalling KiCAD, maybe try older release. When opening the design make sure you have downloaded all design files from the GitHub. Here you can see a picture where I have opened the same design and schematic with KiCAD 7.0.5 without any issues or glitches so the files are fine:

When I close the popup, the KiCad application itself closed.

ESP32 / Re: FYI - network not working ...

This is the best way, it is the reason to have a phy power enable/disable pin in first place.

ESP32 / Re: FYI - network not working ...

Last post by KeviNH - November 29, 2023, 04:57:57 AM

I added the following in setup(), now ESP32-POE reliably gets Ethernet connection and  on restart:

 

Code Select Expand

    delay(350);
    pinMode(ETH_PHY_POWER, OUTPUT);
    digitalWrite(ETH_PHY_POWER, LOW);
    delay(200);
    int success = ETH.begin();

Is there a better way to ensure that Ethernet doesn't start until after ESP32's PHY clock is available?

A20 / LIME2 mini USB power mod

Last post by Jookia - November 28, 2023, 07:34:53 PM

Greetings! I've always wanted to be able to power my Lime2 from USB, but it's never worked properly. I read somewhere that this is due to the PMIC limiting current from USB, which makes sense.

I soldered a 1N5819 diode on the corner of the board under the power plug, with the anode on the side of R67 next to the text, and the cathode near D4's pad on the side near the D4 text. This connects the mini USB VBUS to the 5V EXT rail.

This has managed to let me power the board over mini USB, with the 5V rail running around 4.5V (it usually runs around 4.7V). The diode prevents damage if the board is powered from the 5V rail already.

I've tested this and it seems to work. So I'm just throwing this up here for anyone interested.

Edit: I do want to make clear that this power method is limited to 1A due to the diode. Using a MOSFET as polarity protection or just running a wire and not plugging in both power sources at once would work better, but keep in mind mini USB cables are not generally rated for high power use or charging things.

The project was made with older version but it should work fine with version 7, at least it does here when I test with version 7.

It works fine with KiCAD 7 just when opening the schematic you'd get pop up "Project Rescue Helper" - just close it from the "X" in the corner.

What is the error message that you get or explain what doesn't seem to work at your side?

Hi,

I am using version 7.
