Bare metal application for MPC5748G

[sawrs]

I am looking for a bare metal application source example for MPC5748G. I am interested in the MMU setup. Once I setup the MMU I will load the 'BootLoader_MPC5748G.elf' and follow that up with loading of the application. If the example source file can be compiled in S32DS then it will be very helpful. Your attention and help is much appreciated.

Hi Peter,

I appreciate your patience in replying to all my questions. Thank you very much for your guidance.

Hi Peter,

Thank you very much for your response. I assumed that e200z4 core by default has MMU built-in. Is it fair to conclude the MPC5748G SoC does not have MMU even though it has e200z4 and e200z2 cores? Just out of curiosity how does one disable the MMU in e200z4 core?

Hello,

I assumed that e200z4 core by default has MMU built-in.

There are many different version or e200z4 (like e200z4n2,etc..)

For MPC57xx family, the MMU is only on MPC5777C integrated.

Is it fair to conclude the MPC5748G SoC does not have MMU even though it has e200z4 and e200z2 cores?

No MMUs integrated, even if cores are capable of supporting it.

Just out of curiosity how does one disable the MMU in e200z4 core?

On a core where it is integrated? You do not disable it. As you need always some space to be mapped, even if you running from RAM. Usually you map 1 large table for whole memory, if you don't use MMU actively.

Best regards,
Peter

This device does not contain MMU unit.
