Other Parts Discussed in Thread: EK-TM4C1294XL

I followed the steps mentioned below. I am sending .bin file from LMFlash Programmer. In following code it always go to else condition.
//
// Return control to the boot loader. This is a call to the SVC
// handler in the flashed-based boot loader, or to the ROM if configured.
//
#if ((defined ROM_UpdateEthernet) && !(defined USE_FLASH_BOOT_LOADER))
ROM_UpdateEMAC(ui32SysClock);
#else
(*((void (*)(void))(*(uint32_t *)0x2c)))();
#endif
}
I am using EK-TM4C1294XL board. If I just keep, ROM_UpdateEMAC function it is giving compilation error that ROM_UpdateEMAC() is not defined.

It goes to SoftwareUpdateRequestCallback() function, but upgrade is not happening.
Can you please provide any suggestion why its not working?

Hello Duraiswamy,

Did you include the rom.h and rom_map.h in the file where the above function is being called?

As well as Amit's suggestion to check you are including the rom.h and rom_map.h files, you also need to define a TARGET_IS_* macro to make the rom.h include file define the ROM function.

See the Direct ROM Calls section of the TivaWare™ Peripheral Driver Library User's Guide.

Hello Chester,

As an addition, TivaWare 2.1.4 that is under works will have the Ethernet Update example implemented for EK-TM4C1294XL.
