answering myself but in case it can help others this type of update has to be made as part of a loop screen instruction as in yellow above otherwise it is not working

Hello,

I am aiming at updating a label every seconds but the rendering is always made at the very end of the loop.

Using the https://m5stack.github.io/UIFlow_doc/en/en/Start_programming/Wait.html I was hoping this type of loop would to it.

Is there anything in particular to take into account?

A specific button calls that function, the rest is pretty simple a label being displayed on the middle of the screen.

But instead of seing, 1, 2, 3,....10

Only 10 is displayed at when loop has completed.

I will try to do so deleting it

Great thanks, I will try again later, in the meantime I switched to a Windows machine to make it working.

@ajb2k3 said in M5Paper on macos Big Sur:

I found an issue with the driver and had to select the kext file and now the driver works and usb serial is now working again!

Hi @ajb2k3 what do you mean by selecting the ktext file, something like

sudo kextload SiLabsUSBDriver.kext

me it does not change anything, I am on OS Catalina

I have installed latest driver https://www.silabs.com/documents/public/software/Mac_OSX_VCP_Driver.zip and can see the corresponding extension in /Library/Extensions with

drwxr-xr-x@ 3 root wheel 96 Oct 15 10:46 SiLabsUSBDriver.kext

but then when running M5Burner it only show a tty device of type Bluetooth or usb modem

ls /dev/tty.*

/dev/tty.Bluetooth-Incoming-Port
/dev/tty.usbmodem51850037101

I am running macOS Catalina

Hello @Zontex could you advise me also as I got a similar problem

I guess it is the driver not loading well as I can only see this tty of type modem but I have found no easy way to make it working, I am using the Apple Multi Adaptor (HDMI/USB) on USB C.

hello I got the exact same issue with my mac book pro, I will add some more details, I am using the default apple mac https://www.apple.com/shop/product/MUF82AM/A/usb-c-digital-av-multiport-adapter and then the Burner app, it does display the same option ttyusbmodem something. It would be great to find a workaround to be able to updgrade the firmware and start innovating ;)
