TMS320F28388D: Linker-Generated CRC Tables for Connectivity Manager

Noah Erickson

Tool/software:

Hi E2E,

I'm developing a bootloader for the TMS320F28388D, treating CPU1 as the "primary" bootloader, which has provisions to relay an image to smaller bootloaders on CPU2 and the Connectivity Manager via the IPC feature so they can flash themselves. For my CPU1 and CPU2 application images I'm using the linker-generated CRC table feature in order to validate the image integrity. If available, can I request some guidance on how to implement this for the ARM Connectivity Manager core? The syntax for the C2000 cores doesn't seem to work. Should I be using the "--cmac" option in place of this?

For the C2000 I am using "ti-cgt-c2000_22.6.1.LTS". For the ARM, I am using "ti-cgt-arm_20.2.7.LTS".

Thanks,

Noah

Hi E2E,

I've updated my bootloader scheme so the CM is my "primary" bootloader, allowing binary payload to come from CAN-FD or Ethernet, then routing to the correct target core via IPC. I haven't dug back into linker generated CRCs for the CM core yet, but am still interested if anyone has any guidance on this?

Thanks,

Noah

Hi,

I apologize, we don't have a similar CRC example for ARM. I think this is all the guidance we can give: https://software-dl.ti.com/codegen/docs/tiarmclang/compiler_tools_user_guide/compiler_manual/linker_description/09_linker_generated_crc_tables/linker-generated-crc-tables-stdz0752992.html

Hi Ben,

Thanks for the response. I am using driverlib and at first glance when switching to use the TI Clang compiler, it looks as though driverlib was not written with Clang in mind. I get a quite a few warnings about legacy TI intrinsics being used.

I think I will opt for embedding a CRC into my binary output as a post-build step.
