ESP32 Forum

Hello I have upgraded to the lasted version when I go to compile my code I now get this error
A fatal error occurred: Segment loaded at 0x40156208 lands in same 64KB flash mapping as segment loaded at 0x40156204. Can't generate binary. Suggest changing linker script or ELF to merge sections.

Any suggestions?

Hi jrounds,

What ESP-IDF version were you using before you updated to v3.1.4?

Can you please run the following command and post the full output: "xtensa-esp32-elf-objdump -h build/PROJECT_NAME.elf"

Thanks,

Angus

I upgraded from 3.1.3 see below for output of the command
build/G2.elf: file format elf32-xtensa-le

Hi,

Sorry noone got back to you before now. It seems like there is some problem with the linker script, not all output sections of the ELF are linking properly.

If you do a "make clean" or delete the build directory and then rebuild, does the problem go away?

If that doesn't work, is there any chance you could send us your project privately so we can reproduce?

Thanks,

Angus
