[v3.3-rc1] Error during esptool elf2image: "Found 2 segments that could be irom0. Bad ELF file?" (GIT8266O-429)

[yh-sb]

Environment

• Development Kit: ESP8266 nodemcu board
• IDF version: v3.3-rc1 (816f1d21)
• Development Env: make
• Operating System: Ubuntu
• Power Supply: USB

Problem Description

Can't generate --version=1 binary file using components\esp8266\ld\esp8266_out.ld. I need to have it in order to avoid using extra bootloaders which is working with --version=3.

Expected Behavior

Generation binary files should work OK without providing --version=3 to esptool elf2image. Like in previous SDK version (v3.2)

Actual Behavior

Error during the generating binary from elf file when --version=1.

Steps to reproduce

1. Try to generate bin file from elf using --version=1 (or without specifying version at all) esptool elf2image command:

python /home/user/dev/ESP8266_RTOS_SDK-v3.3-rc1/components/esptool_py/esptool/esptool.py elf2image -o /home/user/dev/ESP8266_RTOS_SDK-v3.3-rc1/examples/wifi/simple_wifi/build/simple_wifi.bin /home/user/dev/ESP8266_RTOS_SDK-v3.3-rc1/examples/wifi/simple_wifi/build/simple_wifi.elf
esptool.py v2.4.0
Creating image for ESP8266...

A fatal error occurred: Found 2 segments that could be irom0. Bad ELF file?

These problematic segments are described in components\esp8266\ld\esp8266_out.ld linker file. It locates .flash.rodata and .flash.text to iram0_2_seg which cause esptool error.
