Compile failed with bootloader.

[msojocs]

Maybe no one still works on it, but I am just want to post it. (

Step

platformio.ini

[env:rtos_iot]
platform = https://github.com/WallaceWilliam/framework-esp8266-rtos-sdk-idf-platformio.git
board = nodemcuv2
framework = esp8266-rtos-sdk
monitor_speed = 115200

1. Initial project, failed.
2. Download xtensa-lx106-elf, and extract it to packages folder.
3. Initial again, failed.
4. Clone https://github.com/espressif/ESP8266_RTOS_SDK.git and overwrite packages/framework-esp8266-rtos-sdk
5. Build failed as following reason.
