ESP8266 native SDK expection

[condemil]

ESP8266 package with native SDK gives the following exception:

Fatal exception (0): epc1=0x40240655, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

With arduino framework ESP8266 is working fine, I can see such behaviour only with native SDK

How to reproduce

• Create native SDK project with your upload_port in platformio.ini

*. Create empty user_config.h under the src folder

• Create user_main.c under the src folder with the following content:

#include "ets_sys.h"
#include "osapi.h"

void user_init(void)
{
    os_printf("SDK version:%s\n", system_get_sdk_version());
}

• Execute platformio run
• Connect to ESP8266 UART with 74880 baudrate, I am using miniterm from pyserial for that purpose

miniterm.py /dev/<YOUR_DEV> -b 74880

Edited: Requested from http://esp8266.ru.

miniterm.py /dev/<YOUR_DEV> -b 74880

Don't forget that you can use platformio serialports monitor command. It also uses miniterm.

@condemil please upgrade PlatformIO to the latest release 2.2.0.
