how to solve device boot loop

Hi, I made a mistake on the device configuration and I assigned a device to a GPIO that is used for the flash.
Now I get a boot loop and do not know how to solve it.
It reboots before the wifi appears, it has the serial port disabled and the reset pin also disabled.
I can upload a new version of software with different default configuration but I still get the boot loop.
I suppose that a solution will be to upload new software and that delete the device configuration, but I do not know how to do it.

Thanks.

You could connect GPIO-0 to GND and press reset. This will force the flash mode when booting and then you can erase the entire flash.

You can upload a blank bin file. I got some here: https://www.dropbox.com/s/g8i2gr26t09l9 ... s.zip?dl=1

Link Rx and TX pin before power on
If Rx and TX is joined during boot the settings will be cleared to original values

Try it

@ayasystems I tried connecting the RX to TX as you suggested, but it does not work.

I forget to mention that I am working with and 8285, I do know if that could the reason because it does not work....


@grovkillen, @TD-er, Thanks for your answers.
I search but I do not find how to erase the flash or upload bin directly to the board or how to erase the flash

You just flash the blank bin as you would flash a firmware bin.
