<![CDATA[m5stack_index.json file signature verification failed]]>Hi,

New user but experienced with Arduino.

I'm getting the above error (or in full http://www.M5Stack.com/download/package_m5stack_index.json file signature verification failed. File ignored) when trying to get started having added the URL as per the littlepaper booklet to the list of boards.

Is this a know issue. I have other unrelated boards added no problem.

using M5 Basic.

thanks

Steve

I tried this - it starts the installation, but gives a message :
Error downloading https://dl.espressif.com/dl/esptool-2.5.0-windows.zip
java.lang.RuntimeException: java.lang.Exception: Error downloading https://dl.espressif.com/dl/esptool-2.5.0-windows.zip
Until now none of the json links worked for me.
Please help.

The forum will be getting an overhaul pretty soon. Thanks for your patience

To be careful...

I want to update this link(https://dl.espressif.com/dl/package_esp32_index.json) for downloading ESP32 Board Support.

this link is out-of-date that need to be replaced by the lastest one(https://github.com/espressif/arduino-esp32/releases/download/1.0.1-rc1/package_esp32_dev_index.json"). The lastest one is 1.0.1-rc version.

Othewise, if we have used the old link(https://dl.espressif.com/dl/package_esp32_index.json), we need to update esp32 board support by "Board Manager" of Arduino IDE

I presume your trying to add the board definitions to the arduino ide

please use this link: https://dl.espressif.com/dl/package_esp32_index.json

that link is out of date, we are currently in the process of updating manuals with a qr code
and link to our docs page to avoid confusion and to avoid any issues with updates.

I think you should have no problem getting set up if your familiar with the arduino IDE already but
just in case check out our video on youtube. https://www.youtube.com/watch?v=U2es-l4z2Zg&t=21s

Hope this helps

Luke
