@robski Yeah I had seen that behavior with it jumping to the right address and then crawling after not finding it.

Hello @turgu

FWIW: in M5PaperS3 the eInk display is directly controlled by ESP32S3.

In M5Paper the GPIO WaitBusy() checks is GPIO27 which comes directly from IT8951 so I guess if the line never goes HIGH either IT8951 is not (properly) powered or defective.

Anyhow, have you tried to change the code to ignore the busy state of IT8951; maybe add some small delay instead.

BTW: I measured GPIO27 and when M5Paper is running it's being pulled up. I don't see a pull-up resistor in the schematics so I guess IT8951 is pulling it up (when not busy).

Thanks
Felix

@obstbauer yeah thats the registers table, I used Uiflow2 with calibration block but you are using not M5Stack controller I see

@kuriko nothing.. It just closes. It comes up with the list on the left. And M5Bruner v then closes..

@robski it is not showing in VS Code. First I thougt that it was a problem of VS Code, that is why I tried it with MU.

@holofloh

Connecting TXD to RXD & supplying 5V to the Grove connector works great! I never thought about studying the schematic right on the device. Thanks for your assistance!

@konacurrents Note, I have a similar startup issue with the Atom Socket and H-Driver.

Anyone know how to stop it starting before I get a change to stop it?

v1.5

Added version to boot animation Cloud source error messages are now more informative Minor UI fixes (hints, navigation, sound)

@ajb2k3 Thanks for the suggestion, but I already looked at that, and decided not to get it, as it's EOL and comes as a kit with a module I don't need.
The plate used in the video is perfect.

@felmue Thanks for answering!
Tried it and now I am getting always chip id 0xFF or 0x0 depended on data order in SPISettings (MSB or LSB first). Tried it with and without battery plugged in but there was no difference.
Any other ideas?

I, too, am looking for clear-cut information on how to update the firmware on several devices using the STM chips on the Unit itself.

I've searched most of the GitHub repos, done web searches, and asked my AI buddies for help, but nothing is directly related to M5 devices.

@tt1296116093 这是正常现象，因为您的额外代码不以块的形式存在。
您需要将额外代码放在“执行代码”块中，以使其不会消失。

@ATARI don't think this is possible to rotate device image based on screen rotation

this code is for StickC/C Plus/C Plus2

@mgrouch What you want is a Stephenson screen case I have one by TFA and the ENVPro has now been outside and working for 6 weeks!

@I_am_Exiled When I get situations lie that I just use M5 Burner to erase and start over

@mumin50 They are releasing it as part of an upgrade kit with an adapter board that should be out next Friday.

@marcelusvictor Did you put the Cardputer into Download Mode as described here? https://docs.m5stack.com/en/core/Cardputer
If Yes, check your device manager if the COM port appears without any error message. If it not apears then your USB cable may be broken or has power wires only (cross check with another one).
