CCS/TMS320F28388D: startup_cm file vs startup_ccs

Part Number: TMS320F28388D

Tool/software: Code Composer Studio

Hi TI

I trying to update an old code from F28M36 on to F28388D.

I am having a problem when it come to the startup file and the third party "enet_lwip" example. How can it be that he is using the startup_ccs.c file which is for the old board?

When i am taking one of you examples the startup file is called startup_cm and is pretty much the same.

He is using the old startup file for an old board. 

Is it possible to use the old startup file for the new board?

Hope it makes sence.

I cant seem to find the Ethernet vector interrupt in the new startup_cm.c file.

  • Hi,

    While it is mostly M4 centric, the g_pfnVectors in startup_ccs.c is ported for the interrupts applicable to F2838x device.

    Ethernet Vector interrupt is not defined in the startup_ccs.c but registered as part of Ethernet_getHandle() API. Please refer Ethernet_init in enet_lwip.c file in the project.
