Other Parts Discussed in Thread: TMS320F28335, CCSTUDIO
Hello!
I am using CCS V3.3, an eZdsp-board with a 28335 DSC and the
XDS510USB-plus external JTAG emulator and I would like to establish
real time data transfer. I sucessfully compiled the provided tutorial
"sect1_less2" (transfer of an array) after I changed the linker command
file to suit 28335's memory tables (see memory listing below) and downloaded it to the controller.
The RTDX configuration panel from CCS looks then as shown below,
so that RTDX should work. Furthermore, I enabled RTDX transfer in CCS and started the provided host application for this example but unfortunately no data were transmitted. While debugging, I recognized that after a long branch directive to the program entry point at c_int00 in boot.obj, .text section was overwritten with the fill-value 0xBEEC from data section .cio (see memory listing below).
After uncommenting the "fill 0xBEEC" comand for .cio section, boot.obj program code worked until a long branch to reserved memory (0x010000 - 0x300000) of TMS320F335 occured (see following screenshot from mixed source/ASM view of boot28.inc).
I guessed that the provided boot routine in "rts2800_ml.lib" might not be suitable for the TMS320F28335 so I included the "rts2800_fpu32.lib", which has worked fine without RTDX. Unfortunately, this produced the error
fatal error: file
"C:/CCStudio_v3.3/bios_5_33_03/packages/ti/rtdx/lib/c2000/rtdxx.lib<rtdx_usr
6.o28L>" specifies ISA revision "C2800", which is not compatible with ISA
revision "C28FPU32" specified in a previous file or on the command line
To sum up, I would like to ask
- Why does the .text section contain initialised data?
- Is the provided RTDX example "...\bios_5_31_02\packages\ti\rtdx\examples\tutorial\sect1_less2\ezdsp2812\" designed to work with an TMS320F335?
- Which boot routine or which libraries except rtdxx.lib do I have to include for RTDX with a TMS320F2833?
Thanks for any advice!
