Dear C2000 expert,
Today I'm trying to use sfra to scan my power topology plant, it works while after downloading .out image, but found that the sfra lib can't work after powering up, it looks that some of data are not stored into flash.
And I view the sfra user guide, that make the libary to be allocated into ram, the cmd file changes as highlighted as below:
.TI.ramfunc : LOAD = FLASH_BANK0_SEC2,
RUN = RAMLS4
LOAD_START(_RamfuncsLoadStart),
LOAD_SIZE(_RamfuncsLoadSize),
LOAD_END(_RamfuncsLoadEnd),
RUN_START(_RamfuncsRunStart),
RUN_SIZE(_RamfuncsRunSize),
RUN_END(_RamfuncsRunEnd),
PAGE = 0, ALIGN(4)
{
--library=sfra_f32_coff.lib<SFRA_F32_inject.obj>
--library=sfra_f32_coff.lib<SFRA_F32_collect.obj>
}
But there are 2 warnings, can you please help on it? Or can you please help me know how to allocate all the sfra lib to flash, and run in ram? Thanks...
"../source/common/cmd/28004x_cla_flash_lnk.cmd", line 156: warning #10068-D: no matching section
"../source/common/cmd/28004x_cla_flash_lnk.cmd", line 157: warning #10068-D: no matching section
Please note that I have add the lib, and lib file path as below:
I'm using F280049 instead of F28069. Here is my map file which inserted sfra lib, is there anything that I missed to allocate to flash?
And here's the SFRA GUI error after device power up again.
Why are you not using the SFRA TMU coff , we release it in v3_00_00_00 of the digital power sdk. sfra_f3_tmu_coff.lib
The error you are pointing to for GUI is unrelated to being able to run from FLASH, it happens when SFRA GUI calculatation fails for BW, GM and PM. You can uncheck the save SFRA Data and it will save the data into excel.
Hi Manish,
Can you please help me know what's improved in using sfra_f32_tmu_coff.lib?
I've just change cmd file to allocate the FPUmathTables into FLASH section, this seems OK.
FPUmathTables: > FLASH_BANK0_SEC10, PAGE = 0
Jack, the tmu lib will run faster , specially the background tasks,
Please see benchmark data http://www.ti.com/lit/ug/spruik4a/spruik4a.pdf?&ts=1590148614030, Table 2
Hi Manish,
Thanks for this info.
Another question, if runs SFRA in CLA, what's specific setting shall to do? Is there any docs about SFRA runs in CLA?
