Not reading config.g on startup.

Also check that you re-named the files mind that wont matter if your loading the FW By Bossac or Samba
I've tried both Boassac and Samba. Neither one seems to work. I tried renaming the files before using Bossac and Samba, doesn't seem to matter.
-
Does any sort of port, or an unknown device, show up in Device Manager (if you are using Windows) when you connect the Duet via USB after flashing the new firmware?
No it doesn't. The windows is a VM on my mac that I can control where the USB ports connect and as soon as I reset the connection goes away and doesn't show up on the mac or the windows.
-
If it doesn't even show up as a COM port or unknown USB device, that suggests that the file you have flashed is not a valid firmware files for that board.
The DuetWiFiFirmware-1.18.1.bin file you downloaded should be 263Kb (268,852 bytes) long.
Also, please make sure that the M552 S1 command in config.g is commented out with a semicolon at the start of the line. WiFi firmware that doesn't match the main firmware can prevent the board running when the WiFi is enabled.
btw it's now possible to flash Duet WiFi firmware using the Bossa program from Shumatec, and there is a build of that program available for Mac.

So I was finally able to get the firmware reloaded. But now I'm getting as before where it says it cannot find the config file.

Cannot initialise SD card 0: Card is unusable -
Have you tried a different SD card?
-
I've tried it with two different cards and with 1.18 firmware and 1.19 firmware. I still get the same Cannot initialize SD card error. Both SD cards are 8gb cards. One is the Kingston card that came with the board. The other is a card that came with my original Tronxy kit.
-
Is sounds like a faulty SD card socket then. Ask your supplier to replace the Duet.
-
Ok. Thanks. This is the second one in a row from that supplier. Any chance this is a whole batch?
-
That sounds most unlikely. The test procedure for Duets reads the test file from SD card, so the SD card socket is known to work when the board passes testing. Are you sure that both SD cards are OK - do they work in other equipment? How often are you removing and replacing the SD card in the Duet?
-
Any chance you're using an SD card extension cable?
How are you powering the Duet? If by USB, have you tried a different USB cable or powering it by the screw terminals?
As for concerns about it being a whole batch, I know you got it from us (Filastruder) and I don't believe we've had any other similar reports.
-
I haven't been using an extension cable. The cards are recognized fine by my computer. I'll try using the screw terminals tonight, and see if it makes any difference.
-
Ok so I unplugged my LCD and now it works. From the wiring diagrams I thought the LCD was in the right connector, but now I'm not so sure.
-
What LCD are you using?
-
I was using the LCD from my Tronxy P802MA kit.
-
no idea if this is a good thing but i turn on my duet wifi with no sd card then off then put the card in and back on and it takes the changes. I am sure there is a better way to do this probably via software but it works for me so stuck with it…
-
I presume you are plugging the LCD into the "LCD" 2x5 connector, and the "SD" connector? That LCD is not yet supported in firmware so its probably interfering. Does the SD card read work fine without the LCD plugged in?
-
I was plugging into the 2x5 connector not the SD connector. The SD card reads fine without the LCD plugged in.
-
Yeah so there must be some interference from that LCD, 20x4 character LCDs are not supported yet either. At least we now know what the issue was!
