I have several Wireless Stick Lites and up to now there have been no problems to flash them using Arduino IDE. Only one brand new board is not working. I am trying to flash a simple program blinking the onboard led and writing some text on serial monitor. Flashing seems to be ok:
Compressed 3072 bytes to 128…
Writing at 0x00008000… (100 %)
Wrote 3072 bytes (128 compressed) at 0x00008000 in 0.0 seconds (effective 819.2 kbit/s)…
Hash of data verified.
I can also read the calibration data so there is no problem with communication:
espefuse.py -p COM21 adc_info
ADC VRef calibration: None (1100mV nominal)
But when I open the serial monitor and press the RST button I get the following message:
18:31:28.473 -> ets Jun 8 2016 00:22:57
18:31:28.473 -> rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
18:31:28.473 -> waiting for download
Program is not running because the led is not blinking. Flashing and running the same program with another Wireless Stick Lite borad is no problem. What is wrong with this board and how do I proceed to get my board alive again?
