m5stack cardputer doesn't turn on.

@ajb2k3 Adam, very interesting. I will look into it.
My first S3 was the LilyGO T-Display S3, which took several weeks and the feeling that I had 'bricked' it by fumbling around. YouTuber Volos gave me insights to rein - in control.
I now have a LilyGO T-Display S3 AMOLED, extremely high resolution and clarity and and a large screen T-HMI, very well engineered, but not enough bit resolution for such a large screen.

Hello @ajb2k3

using M5Burner I've downloaded the below firmware to my M5Cardputer. Then measured G0, G1, G2 and G46 while the firmware was running.

   NEMO for  | Marauder for | Cardputer | Volos Cardputer
   Cardputer | Cardputer    | User Demo | TV Remote
   v2.4.1    | v0.13.6      | v0.9.1    | v1.0
G0   3.3 V   |  3.3 V       |  3.3 V    |  3.3 V
G1   3.3 V   |  3.3 V       |  3.3 V    |  3.3 V
G2   3.3 V   |  3.3 V       |  3.3 V    |  3.3 V
G46  3.3 V   |  0 V         |  0 V      |  3.3 V

Note: Downloading firmware from M5Burner always put the M5StampS3 into download mode automatically - at no point did I have to manually set it to download mode using G0 button.

Note: I am on Ubuntu 20.04

Thanks
Felix

@teastain I thought you was Volos for a while

@felmue Thanks, It looks like that Serial/JTAG is the default mode unless USB OTG is set.

Thats what I though, Nemo and Marauda are pulling G0 high

teastain

@felmue You are thorough.

Is there any way I can reset it so it turns back on?

teastain

@sl4sh00 Yes.
What app did you try to install?
That could be the root of the problem.
The BootLoader firmware is unbreakable, so there is no real problem.

robski

@Sl4sh00 can you try this...press and hold boot button (on side of cardputer or top of stamp) while holding connect usb then let button go, then try to load fresh firmware in M5Burner.

@robski I tried holding down the reset button but nothing happened, is there any other way to install the firmware?

teastain

@sl4sh00 To put it into 'download' mode you can do as @robski suggested or:
Press and hold the G0 Boot button...while holding it in, press and release the reset button, THEN release the G0 Boot.
While doing this you can check the connection status in whatever burner app you are using.
Please tell us if you can see the connection status AT ALL, this would be helpful in solving your problem.

m5stack cardputer doesn't turn on, after I connected it to the computer and tried to put an app on the M5Burner and it didn't turn on anymore and when I plug it into the computer it keeps connecting and

Comprei um cardputer para mim, quero saber como faço para instalar as aplicações do git hub, e só baixar e passar para o cartão sd .

@gera5034 baixa o M5Burner no site da M5. nele vc põe a opção do cardputer e aparece os apps q funcionam nele.
