Writing ELF binary into MPC5748G Flash

bix010 — Wed, 28 Aug 2019 05:55:23 GMT

Hi,

I'm using S32 with PEMicro debugger to write my compiled ELF into the flash of a MPC5748G LCEVB.

For debugging reasons, I also dumped out the full 6MB contents of user application flash. However, I can't find my ELF file in the dumped binary. The ELF magic number can't even be found.

How does S32 copy ELF binaries into flash?

Thanks!

Hi,

S32DS gets from elf raw binary data and write it into flash memory. Elf file is used for symbols and source code location.

Hi Jiri,

Thanks for your reply. Am I correct to say that S32DS discards the ELF headers and only copies the necessary binary sections into their respective physical memory addresses?

Hi,

yes, you are right.
