In my embedded controller application,In order to improve execution speed I would like to copy the function of F280X_BDC_PWM_Update
which in the library F280xDRV_ml.L28 from Flash to RAM.
1, The library path is C:\tidcs\DMC\c28\v32x\lib\drvlib280x\lib\F280xDRV_ml.L28
2,The function of F280X_BDC_PWM_Update will be put in .text.(flash)
3, And then be copped to ramfuncs and run in ram
4, The .cmd is as bellow.
5, How shall I do? Such as how to rewrite the .cmd?etc.
Best regard,
