TMS320F28069: Noinit Section is getting initialized

Tobias Faschingbauer

Part Number: TMS320F28069

Ive run into an issue where i defined a section in the linker script as "NOINIT" and after some debugging i came to the conclusion that it is zeroed out before the main is enetered. Compiler is the latest with EABI choosen. Also in the map file the compression is set to "zero_init" although marked as "NOINIT". Any idea how to resolve the issue or what im doing wrong.

Kind Regard

Hi,

Can you share how the section is defined in Linker Command File?

.persistent : > RAML4 (HIGH), NOINIT
this is the line, currently it gives a warning and says bad section property. If i remove the "," between (HIGH) and NOINIT it builds but seems like its ignored

Tobias,

I think the syntax is like below:

.persistent : > RAML4 (HIGH), type=NOINIT

Have you already tried it?

Tobias,

I want to point you to this link which walks through all the steps required for migration from COFF to EABI. If you have not gone through this, please take a look:
