A20 / Re: On a LIME2 board, after r...
Last post by Nate - January 19, 2023, 03:18:34 amI ended up resolving this another way. As the image supplied by the Freedombox folks uses btrfs for its root partition, a bit of searching eventually led me to this thread:
https://www.olimex.com/forum/index.php?topic=7975.msg30691#msg30691
Here I learned about the btrfs replace capability. It seamlessly moved the data to the HDD (at the moment as the SSD is lost in the mail, apparently) and left a clue on the micro-SD card as to the device the root partition resides.
I did not pursue the Olimex image any further, but I did find mention that all that really needs to be done is to add a line in uenv.txt setting the root partition variable. It seems as though the script could do that easily enough when SPI flash is not available, but perhaps it is not that simple since the Olimex image is all one partition.

Last post by filo - January 18, 2023, 08:46:55 pmYes, this was it. 
I wiped the first 16 MB of the SD card with dd and now the boot proceeds correctly. Some leftovers must have been there even after repartitioninig at the beginning of the SD card that made the SPL pick MMC1 over MMC2.

Last post by LubOlimex - January 18, 2023, 03:34:53 pm> Without spi flash available, is it simply not possible to use the SATA disk as the root partition?
It is possible if you use the SD card to store the data that usually goes to the SPI flash but I don't think our script supports it at the moment. But that is the basic idea, use another SD card that can be used for the task. Oh and edit the script to perform it.

ESP32 / Re: ESP32 ethernet UPD server ...
Last post by LubOlimex - January 18, 2023, 08:33:02 amWhich revision is the ESP32-GATEWAY board?
Probably related to either the configuration or the "Visual Studio code with extension Espressif IDF V1.51" in general. Maybe report to people that maintain "Visual Studio code with extension Espressif IDF V1.51".
Try with our server for either Arduino IDE or ESP-IDF examples:

ESP32 / ESP32 ethernet UPD server spee...
Last post by NielsO - January 17, 2023, 11:44:21 pmESP32 ethernet UPD server speed issue:
When running iperf speed test with ESP32 in server mode the network speed is 0 Mbits/s
As a reference the same test with ESP32 in client mode the network speed is 68 Mbits/s
HW setup:
Olimex gateway board with PHYLAN8710.
IDE:
Visual Studio code with extension Espressif IDF V1.51
Code.
Espressif IDF iperf example
Sdkconfig:
Configured and working with basic ethernet example. Ping is also working.
Iperf example working in client mode.
Steps to reproduce:
Client side CMD (PC WIN10):
iperf3 -c 192.168.0.2 -p 5001
ESP32 server side CMD:
iperf -s
COM output:
If we run the server with recommended parameters from example code.
iperf -u -s -i 3
The server closes socket after 7 seconds.
COM output:

ESP32 / Re: Help with ESP-C3 and ESP-P...
Last post by KNK - January 17, 2023, 08:47:03 pmI figured it out:
1. 'USB CDC On Boot' is 'disabled' by default in Arduino IDE
2. I have the habit to keep the serial monitor opened, but it requires reopen after reboot of the board
Also if instead of Serial.print() i use log_n(), then even with 'USB CDC On Boot' disabled, the messages are printed

A64 / usb0-vbus: disabling
Last post by FalloutST - January 17, 2023, 02:45:27 pmImmediately after trying to load the g_ether module, and trying to manipulate it using sysfs (according to), followed by an attempt to return to g_serial. Led to: usb0-vbus: disabling
Can you help to determine problem...

ESP32 / Re: Help with ESP-C3 and ESP-P...
Last post by LubOlimex - January 17, 2023, 11:13:23 amSo you can program the board via the USB but not get serial output on the same USB? Seems like some bug in the Arduino IDE package. I feel like this should be a well-known issue within the Arduino IDE community for ESP32-C3.
