@selva_tvi yep, those connections are correct.
Whats not clear about them?

@jay_s_uk @gloomyandy Hi, I have tried connecting Octopus pro with RPI.

Octopus Pro side:

Already ESP8266 was connected. Removed that.
Updated the firmware to 'firmware-stm32f4-sbc-3.3.0_11.bin'. Renaming to firmware.bin. Updated successfully.
I used the existing folders - code, macros, www as it is.
Uploaded the new sys files (through the configurator with SBC)
Connected with Pronterface. It was connecting. Movements are happening. But while homing, it showed 'homex.g not found.

RPI Side: (RPI 4 Model B)

Got a new sd card of 32GB
Flashed Duet Pi Lite through Balena Etcher
Created wpa_supplicant.conf in the root folder of boot drive, added the following line: (Used the country as India)
country=IN
update_config=1
ctrl_interface=/var/run/wpa_supplicant

network={
ssid="SSID_OF_NETWORK"
psk="PASSWORD_OF_NETWORK"
}
Kept the SD card in RPI. (Didn't do any extra steps)
RPI powered through Power bank (5V, 2.1A)
Gave the Jumper connections between RPI and Octopus Pro
Except GND all were connected through 100ohm Resistor.
Switched on both the printer and RPI
After 1 minute, RPI showed in Network. Checked with Fing app
When Trying to connect to the network by using duet3d.local/ or the given IP address, it is not connecting.
Following error is coming.

Pls let me know if anything is wrong

jay_s_uk

@selva_tvi that shows you your wiring is wrong so revisit that.
please keep the cables nice and short (under 100mm)
and if you downloaded the latest duetpi image, use 3.4 on the octopus not 3.3

@jay_s_uk Thanks. I updated 'firmware-stm32f4-wifi-3.4.0_1.bin'.

There is confusion with the configuration.

Below are the lines are taken from the below website:
https://teamgloomy.github.io/btt_octopus_pro_1.0_f429_connected_sbc.html

//Config for BTT Octopus Pro v1.0 F429 Version
board = biqoctopuspro_1.0
sbc.TfrReadyPin = D.10

heat.tempSensePins = { F.3, F.4, F.5, F.6, F.7 }
leds.diagnostic = A.13

In the above, Tfr ready pin is given as D.10

But, when i used the configurator for SBC, it is giving the below lines
//SBC Settings
sbc.TfrReadyPin = G.7;
heat.tempSensePins = {bedtemp,e0temp,e1temp}; //Max of 3 entries

Which one is correct? D.10 or G.7
Also pls check the heat.tempsensepins.
Also, should I copy all the sys files from Octopus Pro SD to RPI SD?

My main error is 'Timeout while waiting for Transfer ready pin'.

@selva_tvi said in Ethernet with SBC (RPI) on Octopus Pro F429 board:

I updated 'firmware-stm32f4-wifi-3.4.0_1.bin'.

you need the SBC build not the WiFi build

Use D.10. Looks like I have an issue with the configurator that I need to fix so I will investigate that.

Don't worry about updating the config files yet, just get the connection going first.
The only files you should have on the SD card on the octopus is the board.txt file in the sys folder

@jay_s_uk Great. Thanks . It worked

http://duet3.local/ is working.

Also, I used the IP address and connected. It connected. I copied the sys files to the Octopus Pro board and now it is fully working.

Now, I need only the Ethernet. (As per the client requirement). I hope this maynot be problem. Still the question.

Should I disable the Wifi settings in ' wpa_supplicant.conf file' or delete the file itself? (I didn't find this file in the RPI folder ' wpa_supplicant.conf'

jay_s_uk

@selva_tvi i believe ethernet has priority over wifi so you shouldn't have to do anything

selva_tvi

@jay_s_uk Thanks connections is proper. Later we updated the sys files through DWC itself.

Now axis movements are giving issues.

X and Y is moving. But Z is not at all moving.

We are using BTT TMC2209 - 08nos in the STEP mode only.

In the board.txt, initially we gave as 'stepper.numSmartDrivers = 0'.

Then later changed to 'stepper.numSmartDrivers = 8'.

With this X and Y are moving. Z is not moving.

Also, the commands are taken very slowly by the board. After giving movement, it takes some time to move.
