RTOS SDK : undefined reference to `system_upgrade_start'

[raspberrypidmx]

Hi,

I am using the latest RTOS SDK. My environment is setup correctly. I am able to compile, link and upload non-OTA firmware.

While compiling with the code "if (system_upgrade_start(update) == false)", I get the following error :

user_main.c:678: undefined reference to `system_upgrade_start'

There is no libupgrade provided with the RTOS SDK. Which other lib must be used?

Many thanks in advance,
Arjan

Hello,

There is a file called "upgrade.h", which contains definitions related to what you are possibly trying to do. Let me know if adding that solves your problem.

Hi Pratik,

I have a link error and not a compile error. The <upgrade.h> is already included.

In which library is system_upgrade_start() provided?

Thanks, Arjan

You can refer to this demo of RTOS SDK. There is a folder "upgrade" https://github.com/espressif/ESP8266_IOT_PLATFORM
