RTOS/AM5728: AM57xx-EVM CCS project importing

Hi Rahul,

With Makefile approach i tried to build epwm_duty_cycle_test_app available in examples but i got only object file, there is no .out file. Also that application is written as baremetal program. 

Is there way to create RTOS application just like other application are created using pdkProjectcreate.sh .

Am trying to create Code composer project as you mention in above link but not getting success yet.

Got some error while build as below:

../csl_a15_init.asm:152: undefined reference to `_bss_start'
../csl_a15_init.asm:153: undefined reference to `_bss_end'

is there any example how to create RTOS application for CSL 

Hi Rahul, i read somewhere that CSL examples can be use only for A15. Is there any way to run those applications for DSP (C667x)/M4 cores.
and what will be the make command to build adc/pwm application from CSL using makefile approach

Hi Rahul,
which makefile is used to build CSL example application. I tried below mention command but not get .out file for desired application.
pdk_am57xx_1_0_12/packages/ti/build$ make -s BOARD=evmAM572x OS=linux examples csl_epwm_duty_cycle_test_app .

Also tried with CCS but not succeed til now

Hi Rahul, 

Can i know which makefile used to build pwm & adc csl application examples. As am trying to create CCS project with the help of makefile as suggested in casse of SBL. But getting errors in code composer studio.

In case of SBL makefile is well written having all required information to create Code composer project same will not true in case of other projects. Can i know how to get to know what are the path i need to add in directories & what source file need to be include to build project in Code composer.

Hi Rahul,
Project is created successfully in Code composer studio but getting error while building at padConfig_prcmEnable() in main function of
" epwm_app.c ".

Getting below error:
makefile:144: recipe for target 'pwm.out' failed
./epwm_app.o: In function `main':
epwm_app.c:(.text.startup+0x44): undefined reference to `CSL_xbarIrqConfigure'

collect2: error: ld returned 1 exit status
gmake[1]: *** [pwm.out] Error 1
gmake: *** [all] Error 2
makefile:140: recipe for target 'all' failed


Is that any problem related to symbol , currently added symbols under Build -> GNUCompiler->Symbols:
SOC_AM572x
am5728
core0

if i comment padConfig_prcmEnable() in epwm_app.c , am able to build application in code composer studio for pwm_test application in csl

Hi,

You need to add CSL libraries to resolve those functions. They are under pdk_am57xx_1_0_xx\packages\ti\csl\lib\am572x\a15\release. The libraries are: ti.csl.aa15fg and ti.csl.init.aa15fg.

Hi lding,

I added library you suggest but after adding csl and board related library am getting other undefined symbol error for UART_stdioInit , Then i added ti.drv.uart.ae66 as am building my application for C667x DSP. But these undefined symbol error are coming continuously 

Library i added:

ti.csl.ae66

ti.csl.intc.ae66

ti.board.ae66

ti.drv.uart.ae66

Is there any documentation which suggest what library are needed for particular application. Or everybody have to play-around across all libraries mention in SDK 

As once i added one library another undefined symbol error is generated

Infact with provided makefile its really impossible to build csl example specially which are not listed by TI on its forum but they are part of examples folder.
Their makefile required lots of update to build those examples successfully. Am able to build after done certain updated in make file. But struggling with Code composer studio while building them

Hi Eric,
Am able to create project in code composer studio, take help from makefile logs. Now problem occurs at xds200 debugger end. As i create project for c66x core so try to debug that application using xds200 jtag emulator. But getting error--->

C66xx_0: Error connecting to the target: (Error -1180 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 8.0.903.6)

Only first time when i launch my target configuration am able to debug that application using xds200. But from second time onwards am getting above errror.
Tried various option already mention in forum but not able to debug.
Thanks & Regards
Akash

For debugger issue, please open a new thread. Also clarify if you run the Linux on A15 or not, if you use GEL file on DSP/ARM or not.
