Cardputer COM Not Working

@ariel-jorge @ariel-jorge Hi Ariel! Thanks for the comment.
It didn't work in my scenario. My problem is that the cardputer possibly came with a factory defect. It is not recognized on any machine, whether Windows or Linux (Ubuntu, Fedora, Debian, Pop_OS!) , even with the appropriate drivers installed. This way he can't "lose" a connection he couldn't initiate. I thought it was being recognized by the Arduino IDE, but apparently what appeared in COM5 was my usb hub.
I've been trying to contact the seller since the end of January.
At this point, perhaps you guys understand my frustration. Most likely this seller is not the official one and I probably was scammed.
were are you located? which country? from your posts I can see that it was ok initially then you "lost connection" after downloading nemo firmware correct?
-
@robski I'm from Brazil. The device apparently arrived OK, working with the demo firmware without any problems. On the same day, I tried installing other firmwares, but I couldn't connect with any of them. I wouldn't say nemo was the cause, because it wasn't installed. In fact, the Cardputer continues to work with the demo firmware as it arrived, but I can't connect it. I've already tested it on three machines, Windows and Linux. From what I understand from the suggestions, it doesn't even enter bootloader mode.

would love to help but im in UK,
understand, sorry took that nemo was installed fine and you lost the way to connect to it understand now,
just wonder if you tried to go to boot mode with StampS3 being out from cardputer base?
-
You have tried holding the go button in and plugging in the usb cable?
The good thing about the cardputer is that it runs stock M5StampS3 so you can just very carefully replace the stamp.
Only buy direct From M5Stack or a reputable seller like Adafruit

Hello guys
pressing and holding BtnG0 and plugging in USB only puts the M5StampS3 into download mode if the battery power switch is in OFF position.
With a charged battery and the battery power switch in ON position you'll need to hold BtnG0 and the press BtnRst to get M5StampS3 into download mode.
The reason is that for the M5StampS3 getting into download mode it needs to (re-)start while BtnG0 is held.
Thanks
Felix

@robski No problem, thank you for the help so far. Tried with the S3 disconnected, but no results.
@ajb2k3 Yes, tried that too. The closer to download mode I get is the Cardputer not autostarting when plugged. Maybe I'll need to get another. :(
@felmue Thanks for the comment, felmue! Already tried both ways. As commented above, if I start with the BtnGO pressed, the cardputer does no autostart, wich is progress. However, it doesnt start on download mode too. Both options and it still isnt recognized on the pc/notebook.
Just bought a multimeter, will start to look for damaged components on the board and the S3 pins. :/
-
Have you tried a new data sync usb cable?
-
@ajb2k3 Yes, tried 3 cables on different USB ports, with and without the USB hub I've mentioned.
-
Well, the only think I can think of is to order a replacement stamp and swap it to see if the stamp has gone faulty.
Open M5Burner,
Try taking the plastic cover of the stamp to reveal a button, power on press and hold that button while pressing reset, DO NOT release the button until 5seconds have passed after releasing reset. A blue box should appear in M5Burner giving a new port number
-
@ajb2k3 Yup, tried that button too xD
I'll with the multimeter if I can spot something wrong. If not, I will save some money for another Cardputer or something similar in the end of the year. I'm pretty sure that if I try to replace just the S3, I will mess with it. :(
-
@hanktttop The screen is soldered direct to the StampS3 so you will need to be careful of that when replacing the stamp.
-
Guys, I found out how to make it on mac, where i had same problem. Cardputer off, connect usb cable to it, hold btngo and press btnrst - screen will go dark, release fingers, your in m5loader you'll see popup that its connected.
-
@doko178 Thanks for the comment, doko.
Still nothing even on the device manager. Now I believe I have tried every single button-press combination possible :D
-
@hanktttop What about pressing btngo when connecting usb? Works for me. I hope you'll solve it!
-
@doko178 Tried that some days ago. At least it prevents the cardputer autostart, but nothing about download mode. Thanks for the help xD
-
I posted a guide in the FAQ's
-
@ajb2k3 Thanks, still nothing.
Thank you very much to everyone who commented and helped, but I think I'll stop here. It took so many tries that some of the S3 pins are starting to bend, even though I'm careful when removing/inserting the chip.
I think I could end up damaging the cardputer if I continue with this stress on the components. I must continue my studies with simpler devices like the Portapack Mayhem until further notice.
Thank you very much for your comments, it is a very receptive community.

You can get the StampS3 separately (the core of the Cardputer) and experiment on that.
-
@hanktttop I have the same problem, my cardputer arrived yesterday, a follow all sugestions on this post.
Then I ask on discord channel hackingtroop about the problem, and their sugesto to try another cable, It's works. But one point of attention, the LED don't work as expected, anyway the cardputer enter on download mode.
Hold BtnGO, plug in o cable, and burn firmware. With the new cable, just plug and MM5Burner show pop-up about device found.

@has-oliveira who are you on the cardputer discord
