TMS320F28388D: Lib movement from Flash to RAM

NAGESH RK

Part Number: TMS320F28388D

Hi,

I am using F28388D controller, the question is related to NMI sources.

#if defined(__TI_EABI__)
GROUP
{
ramfuncs
{ -l rts_TMS320F28388D_FlashAPI.lib}
} LOAD = FLASH0 | FLASH1 | FLASH2 | FLASH3,
RUN = RAMLS0123 ,
LOAD_START(RamfuncsLoadStart),
LOAD_SIZE(RamfuncsLoadSize),
LOAD_END(RamfuncsLoadEnd),
RUN_START(RamfuncsRunStart),
RUN_SIZE(RamfuncsRunSize),
RUN_END(RamfuncsRunEnd),
ALIGN(8)

How can i split the Flash Api lib in different RAM locations like for example i want to load flash api lib in RAM1 and application to be stored in RAM0

thanks,

Nagesh,

Are you saying you want to allocate RAMM1 to the RUN address (in above linker snippet) instead of the RAMLS0123? That should be fine as long as it fits in that memory. Did you face any issues? Please provide details of the issue clearly so that we can analyze.

Thanks and regards,
Vamsi

Hi Vamsi,

Yes, in the linker cmd file.i was looking for some reference on how to do it.

thanks,

Nagesh,

You just need to replace "RUN = RAMLS0123" with "RUN = RAMM1".

Not sure if you are asking for something else.

Once you do this, if the code does not fit in the RAMM1 size, then linker will error out. You need to allocate more RAM for that section as it needs.

Thanks and regards,

Vamsi
