Hi,

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.

Regards
Deepak Patel

if you open a Serial Terminal (Putty, idf_monitor) and put your device in download mode you should see this message:
rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
waiting for download
Then you can close the terminal and run "make flash"
