ESP32 / When to expect an ESP32-C6-EVB...
Last post by mw75 - September 15, 2024, 03:09:02 PMThe subject says it all. Would like to order some more ESP32-C6-EVB, but with external antenna.
Thanks for an estimation.

Mario

A20 / Re: eMMC, NAND, and SPI Flash ...
Last post by LubOlimex - September 12, 2024, 02:42:43 PMeMMC can be used as additional storage, but it can also be used as boot medium (after you run olinuxino-sd-to-emmc it will transfer the Linux from the SD card to the eMMC)
Hard to say if it will improve performance, it would depend on the SD card you are using. Some faster cards might be faster than the eMMC speed. I guess it can be tested empirically just dd some large file and check the average transfer speed when copying the file from one location of the card to another and when writing it from the card to the emmc and when writing the same file from one location of the emmc to another location on the emmc.
By the way you can also attach SSD or hard disk to the board, it can also be used as storage or boot medium. You need a 5V hard disk and this cable set:

A20 / Re: eMMC, NAND, and SPI Flash ...
Last post by HardDriveStand214 - September 12, 2024, 09:58:32 AM> What do you mean by home media server? What media are you going to play? I am not sure if the A20-OLinuXino-LIME2 boards are suitable for playing high bitrate videos. About the questions:
More of a storage backup sever than anything. As long as I can use it to automatically save files to a USB storage device.
_______________
Is eMMC just like additional storage (as if you were utilizing a USB, SD card, etc.)? Or does it help improve processing power?
Thank you so much for your help. I immensely appreciate it.

Last post by Mattis Fjallstrom - September 11, 2024, 08:52:39 PMGood news!
I couldn't get Balena Etcher to work right on my Linux machine, but in the end it didn't matter. I re-flashed the SD card (using dd), tried it again, and it worked this time. All good. Thanks!

A64 / Re: Olimex A64-OlinuxIno-1G no...
Last post by LubOlimex - September 11, 2024, 08:27:41 AMMost of the problems with first time boot are related to the SD card and the preparation. If the SD card was faulty or if there was something left over on the card when you ran dd there would be nothing. If re-writing with Balena Etcher doesn't make it work, maybe the card is faulty, try with another one.
Refer to page 7 of chapter "2.3. Download the image to an SD card" on common problems with the cards and preparing the image:

Last post by Mattis Fjallstrom - September 10, 2024, 07:20:52 PMThanks for the reply.
That is the image I'm using, and I'm using the 5V power-supply that was recommended for this board on Olimex website. The red LED (indicating power) comes on when I connect it.
I've tried switching RX/TX and yes, GND is connected. Still nothing at all, not even garbage. I've also tried switching out the UART/USB cable for another one (that I know works with a different board computer). Still nothing.
I'll try Etcher - I use dd on Linux out of habit. Still though, even without an SD card, shouldn't there be _something_ on the UART? Some boot information?
For the UART, I'm using 115200, 8/1, and I've tried both None and Xon/Xoff for flow control.
Thanks again, let's see if we can get this fixed!

ESP32 / Re: ESP32-POE-EA-IND
Last post by LubOlimex - September 10, 2024, 03:03:10 PMNo, but you can measure if there is voltage and how high it is between those two grounds before connecting them.

ESP32 / Re: ESP32-POE-EA-IND
Last post by DarthWeber - September 10, 2024, 10:18:57 AMokay, wouldn't it be then better to connect the GND of the power source width the GND of the Ethernet?

A64 / Re: Olimex A64-OlinuxIno-1G no...
Last post by LubOlimex - September 10, 2024, 08:09:24 AMTry preparing the card with Balena Etcher.
Make sure you are using the image from this archive: "A64-OLinuXino-bullseye-base-20231106-081613.img.7z"
Make sure to power the board from the power jack. It requires 5V DC only.
Try changing the RX and TX wires of the serial connection, sometimes people swap those. Make sure GND is also connected.

A64 / Olimex A64-OlinuxIno-1G not st...
Last post by Mattis Fjallstrom - September 09, 2024, 11:45:31 PMI wonder what I might be missing.
My A64 board isn't booting - the power LED turns on when I connect power, but nothing shows up at the serial port, and the HDMI connection is also dead (according to my monitor, at least).
I've followed the quick start tutorial - first for UART, then for HDMI. No luck. I programmed the SD card using 'dd' on Linux, but even if that went wrong, shouldn't I see something on the serial port?
Can you recommend any points on the board that I can check with a multimeter to make sure it's running properly?
Any advice much appreciated.
