ESP32 Forum

Hi,

I developed with the latest esp-idf, when I compile my project, I got the following error message: Segment loaded at 0x3f407a98 lands in same 64KB flash mapping as segment loaded at 0x3f400010. Can't generate binary.

What does this mean? Is there any suggestion to solve it? Thanks.

Does a 'make clean' solve anything maybe?

Please run and post the output here.
Thanks.

@ESP_Sprite "make clean" is useless

@ESP_igrr the dumped info is as below:

Thanks.

You have an '.irom.text' section in your program but it is not placed anywhere in the linker script.
You need to remove function attributes that assign functions to this section. My guess is that you are moving code from the 8266 and use something like ICACHE_FLASH_ATTR.

@ESP_igrr Yes, you're right. It works. Thanks.

I'm new to vscode and esp-idf.
How do i run the line mentioned above? (xtensa-esp32-elf-objdump -h build/yourprogramname.elf)
I'm having the same issue.

this is the output of the code. dont see any .irom.txt
