eFuse error with MicroPython firmware

andrewm

Hi,

I'm following these instructions for setting up my M5Stack Fire for MicroPython:
http://forum.m5stack.com/topic/67/micropython-on-webide-1-prepare-and-hello-world

I have successfully erased the firmware and am attempting to burn m5cloud-20180516-v0.4.0.bin on the device. When I press 'Start', however, I see this in the logs:

main.py:96: wxPyDeprecationWarning: Using deprecated class PySimpleApp.
('self.chip: ', 'ESP32')
RF option applied...

CONNECT BAUD: 115200

![Here's a screenshot of my settings in the Espressif firmware tool:

What can I do to get past this error and burn the new firmware to the device, please?

That guide is out of date, if you install the UIFlow firmware they you have access to micro python via the UIFlow interface and via REPL

Thanks for your quick reply. The link to the M5Burner executable for Windows - https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/software/M5Burner.zip - is dead. Is there another location to download this from, please?

@andrewm Check out this wip guide. you use the link in UIFlows settings.
