Hi,

We are trying to initialize stack, CPU , RAM on T2080ARDB but we are not finding basic baremetal boot code for initialization.

Could you please help us with any pointers or reference to look into?

Thanks,

There are no such separate software components from NXP.

Available complex reference is U-Boot source code from the Linux SDK.

The SDK v2.0 can be downloaded from:

Thanks for the response.

I installed SDK on linux and my need is to get start.S file for T2080rdb e6500 core.

I migrated to below path after sdk installation:

/QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb-64b/tmp/work/t2080rdb_64b-fsl-linux/u-boot-qoriq/2016.09+fslgit-r0/git/arch/powerpc

I couldnt find the start.S for e6500 power pc core .

Could you please suggest something?

Thanks.

The same "start.S" is used for all processors of the "mpc85xx" branch including T2080.
