Description Alan DeMars CLA 2011-05-11 12:29:22 EDT 
Build Identifier: gep-c03

In the absence of explicit placement of the .args section, the linker attempts to place it at location 0, which is the "SFR", a memory mapped MSP430 core register. This causes problems when CCS tries to load the application onto the device. A memory initialization error results.

Reproducible: Always
Comment 1 Sasha Slijepcevic CLA 2011-11-04 19:14:12 EDT 
I added the code that sets argSize to 0, in ti.platforms.msp430.Platform.xs. The code runs before the user's script, so the user has a chance to overwrite it if needed.
Comment 2 Sasha Slijepcevic CLA 2011-11-04 19:14:35 EDT 
The fix is in 3.23.00.26.
Comment 3 Alan DeMars CLA 2011-11-15 14:12:50 EST 
Verify Pass

1) Using CCS and xdc tools 3.23.00.29, I built the SYS/BIOS msp430 stairstep example.

2) I then removed the explicit setting of the "Program.argSize = 0" from the config script, cleaned, and rebuilt the testcase.

3) I inspected the generated linker command file and observed the expected:

   "--args 0x0"
