paper s3 Get mac failed

jahaan2311

Hi everyone i'm new to the m5 ecosystem and the paper s3 is my first device, I'm trying to burn the uiflow 2.0 for s3 firmware to it but I keep getting a "GET mac failed" error.

For more info, when I plug in the device, it recognises it and brings up the usb port it's connected to, The when I press burn, it loads fo a second, the paper s3 restarts, m5burner loses connections fora couple of seconds then reconnects when th s3 has finished restarting. All this happens while it is still trying to "Burn"

for computer details, i'm using an M2 macbook air 16inch running the latest macos Sequio with Xcode installed

@jahaan2311 The "GET mac failed" error when burning UIFlow 2.0 firmware to your PaperS3 (SKU:C139) typically relates to communication issues during the flashing process. Here are the recommended steps to resolve this:

Ensure Correct Download Mode: When connecting the PaperS3 to your Mac, make sure the device enters download mode properly. The screen should remain blank after connecting, indicating it's in programming mode.

Verify M5Burner Setup:

Confirm you have the latest M5Burner version installed for macOS
Select the correct PaperS3 firmware in M5Burner
Double-check the USB port selection matches your connected device

Check USB Connection:

Try using a different USB-C cable (preferably a data cable, not charging-only)
Connect directly to your Mac's USB port instead of using a hub
Avoid using USB-C adapters if possible

Reconfigure Burning Settings:

In M5Burner, click "Configure" before burning
Verify all Wi-Fi settings are correctly entered
Ensure the baud rate is set to the recommended value (typically 115200)

macOS Specific Considerations:

Ensure you have the necessary USB drivers installed
Check System Preferences > Security & Privacy for any blocked developer extensions
Try restarting your Mac and the PaperS3 device before retrying

If the issue persists after these steps, please try burning the factory firmware first using the PaperS3 Factory Firmware and then attempt the UIFlow 2.0 firmware again.
