dynamic memory allocation in MPC5744P

mayurbankhele — Wed, 15 Jun 2016 09:46:48 GMT

Hi All,

We are using MPC5744P controller.

We want to implement the dynamic memory allocation.

To allocate memory at the run time what masking bit we have to set, which register we have to use.

We are not sure about it.

Can we get the sample application or example set how to set the dynamic memory allocation in CMPU and SMPU.

Regards,

Mayur Bankhele

Hi,

could you please clarify, which IDE you use?

Neither CMPU nor SMPU are related to dynamic memory allocation. This is the function of compiler. Please look at the functions malloc and free in C language.

Regards,

Martin

Hi,

We want to know about the resister setting of SMPU_CESR0, SMPU_CESR1, SMPU_RGDn_WORD2 at the time of dynamic memory allocation. We want to restrict the access for protected region. or any sample application used for same.

Hi,

please look at the following example:

Example MPC5748G SMPU initialization

This example is created for MPC5748G, but SMPU module is nearly the same as in MPC5744P.

If you have any other question, please feel free to write me back.

Martin
