ESP32-s2 & Whippersnapper says offline cannot update

Post by Fibbermcg »

I have followed the steps for whippersnapper installation, but I cannot drag and drop the uf2 file. I get the board to have the green light (after double reset press), file manager shows 3 files on screen for the drive. I then drag the new uf2 file and see the transfer graph and a blinking light on the esp board. BUT nothing. no file transfer or re-boot to whipper. what am I doing wrong. I checked the cable to my phone to see data and it is reading data.

You need to enter bootloader mode on the the ESP32-S2 so that that the device will boot with a drive name like FTHRSBOOT (if you are using a Feather ESP32-S2) names will vary, but the 'BOOT' part is important. Then you can drop the WipperSnapper drive.

Code: Select all

To enter ROM bootloader mode, hold down DFU button while clicking reset button mentioned above.
