Part Number: LAUNCHXL-F2800157
Other Parts Discussed in Thread: C2000WARE

Tool/software:

I have import uart code from sci_ex1_echoback and i'm trying to make a rtos task that runs the uart code. When i attempt ot compile/build i get the following error.

undefined first referenced
symbol in file
--------- ----------------
F28x_usDelay ./f280015x_sysctrl.obj

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "freertos_ex1_c28x_led_blinky.out" not built

In linked resources c2000ware is properly pointed to and i can see f280015x_examples.h in the includes folder. Why am i still getting this error?

Any help would be amazing.

Hi Eric,

Please ensure that ...\F280015x\driverlib\sysctrl.c is added to your project. I suspect this might be the issue.

If that does not solve your issue, can you please refer to this thread and see if the solution helps:

I added the sysctrl.c to the project that didn't work same error and i also tried the link to files found in the thread you sent same error. I checked and a file has extern void F28x_usDelay(long LoopCount); I must not have the file that has the function declaration if i'm still get this error.

i figured it out you need to add f280015x_usdelay to the project. its found under device_support/f20015x/common/source/f280015x_usdelay.asm
