Part Number: TMS320F28335
Hi,
I am implementing a DSS script and would like to return a non-zero code when the script fails for whatever reason.
Please advise how to do this.
I am using the dss.bat, thus:
C:\ti\ccs1040\ccs\ccs_base\scripting\bin\dss.bat Z:\DSS-Scripts\dss-flash.js --ccxml '"C:\TMP_CAP_DIR\SP3_0_5_Target.ccxml"' --mask 80 --cpu 1 --key - --app '"C:\TMP_CAP_DIR\SP3_DSP.out"' --chk -
My script is attached but renamed as a text file.
Thanks,
Jason
