Flash programming: Is RAM required on the target board to load the flash driver or can the cache in a P4080 be used?

[peterpetrowich]

Id the cache can be used, how do I do that?

Thanks!

Hello Peter Petrowich,

CodeWarrior provides SRAM initialization file P4080DS_init_sram.tcl in CW_PA_<version>\PA\PA_Support\Initialization_Files\QorIQ_P4 to configure internal CPC as SRAM to avoid using DDR.

If you use the recent released CodeWarrior, when creating a bareboard project following new project wizards, please select "Download SRAM" or "Connect SRAM" launch configuration, then use it to connect to the target board.

Another method, you could configure CodeWarrior initialization file as <installation folder>\CW_PA_<version>\PA\PA_Support\Initialization_Files\QorIQ_P4\P4080DS_init_sram.tcl from Run->Debug Configurations-><project>-core00_RAM_<processor>_Download(Connect)->Edit->Edit->Initialization->Initialize target script.

Have a great day,
Yiping
