KAA ESP8266 Queries

Question

I compiled configuration demo for ESP8266 by using Xtensa-lx106 GNU

file demo_client

demo_client: ELF 32-bit LSB executable, Tensilica Xtensa, version 1 (SYSV), corrupted program header size, not stripped

Could you please tell me, how can i flash this application to ESP8266 by using espytoo.py and how to test it.

I also not able to get GPIO ESP8266 controll application in my sandbox image. Could you please tell me how can i test gpio control application with nodemcu esp8266 and android app.

Thanks

Answer 1

To create a binary from the ELF file:

esptool.py elf2image demo_client

After this, to flash the board with the application:

sudo esptool.py write_flash 0x00000 demo_client-0x00000.bin 0x40000 demo_client-0x40000.bin

If necessary, you can specify the serial port with --port argument.

Regarding GPIO demo for ESP8266, here is an example of GPIO slave application that works with Kaa 0.10.
