TMS570LC4357: Bootloader jump cause a dataentry abort

Hi Furka,

Apologies for the delay, here in India we got consecutive holidays:

jump_add_u32 = (uint32_t)OP_FW_JUMP_ADD;

((void (*)(void))jump_add_u32)();

I don't see any issues with this code, this looks fine to me. Make sure you are calling the right address according to your application.

And we have CAN bootloader examples in below git link:

SafetyMCU_Bootloaders « Bootloaders - hercules_examples/hercules_examples - Software Examples for Hercules Processors (ti.com)

You can refer them and can make the changes in according to it.

If this doesn't solve your issue, then either you can share your complete project through private chat or else we can setup a live debugging session.

Hi Jagadish,

I am sure about the jump address. I checked from memory map. I refer from your examples and the code working very well until memory jump part. When I came this part I could not succeed and get data entry error there. If we can plan a live debug session I would highly appreciate it.

Best Regards,

Furkan

Hi Furkan,

We will setup a live debugging session, before that i want to verify your application and bootloader linker cmd files.

Is it possible to share them? And also mention the address you are calling?

I mean value of OP_FW_JUMP_ADD?

Hi jagadish,

Of course i can share them. Can we share these data with private chat ?

Also OP_FW_JUMP_ADD means application software start address which equals to Flash Bank 1 start address.

Best Regards,

Furkan

Yes, you can share with them through private chat. Please accept my friend request, once you did that you could share the files through private chat.

I sent these files.

Best Regards,

Furkan

Sorry about corruption our internet connection was broken for a hour that is why ı could not turn back to meeting.  I will try your what you said.

Hi Furkan,

No problem.

I think you understood the main problem, the bootloader overwriting the application vector memory with application code, because of this jump to the application is not taking properly.

The method we discussed before the call disconnected, also will not work because still our jump address is 0x200000 but the jump should be at 0x1FFFE0.

However, i think you understood main problem, just verify it in that way and do the necessary workaround.
