MCU-PLUS-SDK-AM243X: How to avoid warning of sbl_ospi

Hi,

I would suggest you to take a look at the default SBL OSPI and the different sections configured in SysConfig.

Then you can go ahead and modify it further.

creating output section ".app" without a SECTIONS specification

I think this message is coming while building the application? Or while adding any subsection/configuration inside SysConfig?

Hi Vaibhav,

It occurred  while building "default" application mcu_plus_sdk_am243x_11_00_00_15.

This is the log.

Hi,

Please allow me sometime to read through this and get back to you.

Thanks for your patience.

Hi,

I am not facing any build warnings/error.

Can you head to your .map file?

Your built application will contain the file:

sbl_ospi.debug.map and sbl_ospi.release.map

Does it contain a section under Output called .app? and is main.obj uninitialized there?

Regards,

Vaibhav

Hi Valibhav,

.app       0    70023000    00040000     UNINITIALIZED
                  70023000    00040000     main.o (.app)

Only .app is called under Output in the sbl_ospi.debug.map.

 I will share my tools details.

CCS : 12.8.1

compiler : TI Clang v4.0.1LTS

sysconfig : 1.22.0

MCU + SDK for AM243x : 11.0.0.15

Hi,

Pretty sure this warning should not interfere with your build process or the way your application runs.

Please allow sometime for another expert to comment on this thread.
