But when i downloaded .bin files to board, blue led of board which is communication led indicator for us is not turn on and i cant wake ALEXA. Please help me.

Hi walker34,

Can you please tell what do you see on the console when the device boots up?

Also, we are planning to release new MSC release shortly which will be C based implementation of Alexa and would be much more stable and feature ready.

Hi walker34,
Can you please try unchecking "DoNotChgBin" and check "SpiAutoSet" in the flashing utility? It appears that flash size being detected is incorrect.

Hi ESP_Amit,
Thank you for responding. I tried it, but i failed again. My dealer send new .bin files. The error which was mentioned is gone after I used new lib, but I have been giving a new trouble. The flash chip resetting by itself.
This is the error code:
rst:0x10 (RTCWDT_RTC_RESET),boot:0x3f (SPI_FAST_FLASH_BOOT)
flash read err, 1000

What can I do about it?

Sincerely yours,
