<![CDATA[New M5stack Show MPU ERRORs]]>This is a brand new M5Stack. On attaching a usb power bank the M5Stack Logo screen appears, then a list of errors:
MPU9250 ERROR
AK8963 ERROR
Wifi RSSI ok
SDCard ERROR
ADC34: Various numbers
ADC35: Various numbers
ADC34: 0000

I have been through the forum entry "Let's start! Hello world"
When I upload the Arduino sketch. I get "....._____" x10 returned, with a communications error message, which I have seen before using a ESP32 chip, that was fixed using the boot/enable button.
Have I got a Hardware problem?
The funny thing is this is the second M5stack that I have bought with exactly the same problem.
I'm pretty sure that I am doing the installation correctly.
Am I just unlucky, stupid or is there an generic M5stack problem

The COM port is open and selected. When I try the hello world sketch I get the following error:

A fatal error occurred: Invalid head of packet ('5')

Thanks for any help.

First, refer to the the section 2 of this article for comfiring the USB driver has been installed.
https://m5stack.readthedocs.io/en/latest/get-started/establish_serial_connection.html
Second, if usb driver has not been installed, then install it refer to the article "Establish Serial Connection"
Third, try to set up the development environment on MacOS again, then we analyse the problem.

And idea why I am getting those errors? I get them even when I plug it in to an external battery. Do I have a bad one?

I have a brand new on I got from Amazon and I have the same issue.
MPU9250 ERROR
AK8963 ERROR
WiFi RSSI OK
SDCARD OK
ADC34:0800
ADC35: 0018(fluctucates)
ADC34: 0000

I am not able to upload any sketches to the device using my Arduino IDE. I am new to all of this.

I think the problems are all to do with the connectors to the back panel. I have found that applying pressure to the back has gradually allowed the +5V to rise to its proper level, as if the battery is charging. I shall see if the other one has the same problem.

Don't worry, it just a factory testing program. To avoid making customers confused, we have already changed it.

Btw, about the problem one, it can not upload any program right ? Did you buy in our store ?

Both had the same problem when trying to upload a sketch. One of them has since died. Yes I have checked through all the steps shown on github, but still getting time out errors.

That list of errors is just a factory testing program and it is normal for the basic version.

Btw, both your two M5stack all have the '....._____' returned problem ? Have you checked all steps install correctly as our github showed? https://github.com/m5stack/M5Stack
