TMS320F280049: Unresolved symbols when choosing EABI format output

Hi expert,

I am building below project and meet some error when I choose EABI as output format. I am not sure which compile document should I refer to to solve this issue.

I am use CCS 10.0 for below project and just change the output format before a build.

C:\ti\c2000\C2000Ware_3_01_00_00\device_support\f28004x\examples\launchxl

Error message shows:

Sheldon,

I tried myself on CC9.3, and I encountered similar issue.

I was able to resolve the issue by changing cmd file:

SECTIONS
{
   codestart        : > BEGIN,     PAGE = 0
   .TI.ramfunc      : > RAMM0      PAGE = 0
   .text            : >>RAMM0 | RAMLS0_LS3 | RAMLS4,   PAGE = 0
   .cinit           : > RAMLS5_LS7,   PAGE = 1

   .switch          : > RAMM0,     PAGE = 0
   .reset           : > RESET,     PAGE = 0, TYPE = DSECT /* not used, */
   .stack           : > RAMM1,     PAGE = 1


#if defined(__TI_EABI__)
   .bss             : > RAMLS0_LS3,     PAGE = 0
   .bss:output      : > RAMLS5_LS7,     PAGE = 1
   .init_array      : > RAMM0,      PAGE = 0
   .const           : > RAMLS5_LS7,     PAGE = 1
   .data            : > RAMLS5_LS7,     PAGE = 1
   .sysmem          : > RAMLS5_LS7,     PAGE = 1
   .bss:cio         : > RAMLS0_LS3,     PAGE = 0
#else
   .pinit           : > RAMM0,      PAGE = 0
   .ebss            : > RAMLS5,     PAGE = 1
   .econst          : > RAMLS5,     PAGE = 1
   .esysmem         : > RAMLS5,     PAGE = 1
   .cio             : > RAMLS0_LS3,     PAGE = 0
#endif

You will also need two more changes in f28004x_sysctrl.c and f28004x_examples.h

change F28x_usDelay to _F28x_usDelay

I will create a bug to track the fix in C2000ware.
