Hi Ti,
I am a newcomer for developing dsp. I am trying to use ccs to debug the dsp side codes of the notify example in syslink on DM8148. The versions are:
ccs 5.4.0
sys/bios 6.35.1.29
ipc 1.25.0.04
xdctools 3.25.0.48
syslink 2.0
First I create and build the notify project in ccs as http://processors.wiki.ti.com/index.php/Creating_CCS_Project_for_SysLink_samples?keyMatch=creating%20ccs%20project&tisearch=Search-CN said. But I do "not" set the build options as "-DSYSLINK_PLATFORM_TI81XX" because of the different versions of ccs between mine and the authors. Also I do "not" set the configuration script arguments type as "{dmTimerFreq: 32768}" because the example would be stuck behind ipc_start() if so. And I changes the Timer.intFreq.lo as 20000000 in .cfg file.
Based on the above settings, I build the project and get the .out file. But there are two warnings "#10063-D:entry-point symbol other than ' _c_int00 specified ' " and "#10247-D:creating output section '.plt' without a SECTIONS specification". It seems nothing matters. In order to verify the correctness of the .out file or my settings, I download the .out file into the platform's filesystem and run in the same way as the .xe674 file in syslink. The results are the same. I think my settings are correct, am I right? But the sizes of the .out file and the .xe674 file differ largely. Is it because the difference between windows and linux? Oh, I’m digressing here.
Then, I begin to debug the codes on dsp side as follows:
1. Startup DM8148 and the dsp core: ./slaveloader_debug startup DSP ./notify_ti81xx_dsp.xe674
2. Startup ccs, debug .ccxml, right click on dsp core and select "connect target". Although it prompts one error "No source available for '0x8b0168fc' ", but I ignore it. After I load the symbols, it should spin on Ipc_start(), but it halts on ti_sdo_ipc_GateMP_start() in the GateMP.c file.
I have consulted many threads but got no way. I have tried my best. Is anyone willing to help me? Thanks!
