[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.

[engdavidiogo]

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

[fdcavalcanti]

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

[fdcavalcanti]

Hi @engdavidiogo. #13795 Should fix this issue.
Thanks for the help @almir-okato.

[fdcavalcanti]

I saw that PR fixed the build issue but WiFi stopped. I jumped the gun on that PR, sorry about that. Still working on it.

[FelipeMdeO]

Thank you for the effort.

[fdcavalcanti]

Hello. So I noticed you guys still had issues on that linker fix.
There is a different issue going on regarding WiFi stability that was affected by a different merge request.
As soon as that is fixed, I will reopen that linker MR and it should be good. Just tested on a C6 using those fixes and its working as expected.

[engdavidiogo]

Hi @fdcavalcanti, good news.
Are there any issues related to this fix?

Furthermore, I understand that you were able to track down the commit that caused the break. Could you share your successful test scenario

[fdcavalcanti]

Yes. You guys got tangled between two issues.
One is the one you reported, which was fixed on #13795. I can't submit that until another issue gets fixed, which is #13814.

Here's the output using the defconfig you provided previously, connecting to my WiFi hotspot:

nsh> wapi psk wlan0 espubuntu123 3
nsh> wapi essid wlan0 espubuntu 1
nsh> renew wlan0
nsh> ifconfig
wlan0	Link encap:Ethernet HWaddr 60:55:f9:f6:06:04 at RUNNING mtu 576
	inet addr:10.42.0.199 DRaddr:10.42.0.1 Mask:255.255.255.0

nsh>

@FelipeMdeO could you try this patch #13841?

[fdcavalcanti]

Looks good. Already reopened the PR for linker fix and this issue would be done.
