Cardputer COM Not Working



  • @teastain I have a Windows 11 and a Linux machine with Ubuntu (a few days ago I tested using Fedora). Cardputer works with the demo. It's the firmware it arrived with and the same one that runs normally when I turn it on currently.

    I have some arduinos, Uno, Nano, Lilypad, a LoRa module, all these devices are working normally, they are recognized without problems. Right now I'm using a multimeter to check if any S3 pins have problems (I'm not that experienced with hardware), but they all seem ok. I even think that even the demo wouldn't work if there were problems with them.



  • I only have windows 7 (yeh old) but it would appear that the issue is how windows is handling the Chinese drivers ie, if the driver wasn't made by Microsoft, windows is trying to block the driver.



  • @hanktttop can you help me ? mycardputer not turning on

    @hanktttop can you help me ? mycardputer not turning on

    Have you charge it and tried the power switch?



  • @twinturbo I did'nt solved the problem yet, and I'm pretty novice with it, but explain what's your problem and maybe someone else can help.



  • Boa noite, colegas!

    Eu acredito ter resolvido esse problema, tente fazer da seguinte maneira:

    1 - Com o cabo conectado ao Cardputer clique para fazer o Download de qualquer aplicação;

    2 - Quando estiver executando aperte ao mesmo tempo o "BtnGo" e o "BtnRst", com isso irá aparecer outra mensagem de erro informando que o dispositivo foi desconectado;

    3 - Em seguida tente novamente fazer o Download de qualquer aplicação para efeito de teste e o Cardputer vai funcionar normalmente.

    Esse foi o que eu fiz e deu certo, tente fazer dessa maneira e verifique o que dá... Espero que funcione para você. TKS



  • @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.



  • @hanktttop

    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
