[HELP] Image size error after enabling wifi on esp32c6-devkitc:mcuboot_nsh

[engdavidiogo]

Description

I'm trying to run a demo of MCUboot and NuttX on my ESP32-C6. By configuring the project with esp32c6-devkitc:mcuboot_nsh, I can compile and burn the firmware on the ESP32 without any problems. However, when trying to enable Wi-Fi in my settings, I start facing issues related to image size.

I studied both projects and tried to configure them according to the information below. Please let me know what I'm doing wrong or what would be the best approach to tracking down the root cause of this issue.

Hello @fdcavalcanti can you help us to do it work, please ?

[fdcavalcanti]

Hello, thanks for reporting. Will try and replicate it.

[fdcavalcanti]

It seems like an issue with imgtool. The 0x50000004c image size seems excessive.
Can you check the .hex file size?

Some things to try:

• On bootloader configuration, try to modify the hash to the newest mcuboot version.
• Update imgtool to newest version using pip.

I just followed your instructions but I still have the same behavior.

Thanks for the info. Could be a linker issue, looking into it.
