Esp32 new IC programming issue

Postby Deepak » Sat Dec 30, 2017 7:02 am


I am using new esp32 IC with new flash. I have made GPIO0 pin zero an also GPIO2 is set to ground. Now when I power on the device and try to make flash or try to download firmware using ESP32 FLASH DOWNLOAD TOOL, my firmware does not get downloaded.
I get an error as "waiting for packet header...". if I try to program with FLASH DOWNLOAD TOOL It responds me with its MAC address but program does not get flashed.
Please help me to solve this issue.

if you open a Serial Terminal (Putty, idf_monitor) and put your device in download mode you should see this message:
waiting for download
Then you can close the terminal and run "make flash"
