Compiler/TMS320F28069: Boot ROM Issues

TMS320F28062F: Jump to SCI_Boot in Boot ROM from application

Part Number: TMS320F28062F
Other Parts Discussed in Thread: CONTROLSUITE

I have successfully used the ROM bootloader on the F28062 to boot from SCI. I've seen forum topics describing methods of jumping directly to the SCI_Boot function in ROM using software rather than the Boot GPIOs and would like to try this. However, I'm not finding the address of the SCI_Boot function. I've found the Boot ROM source code and output files in ControlSuite but there is no map file to get the symbol info from. Where might I find this?

Thanks,

Ben

    I was able to load symbols from the .out file in the ControlSuite boot rom project and found SCI_Boot at 0x3FF698. Is this correct?

    Ben,

         That is correct. Note however that the device may be at a different state when you are calling the SCI bootloader from the application. i.e. the device state (in terms of PLL and WD settings) may be different between invoking the loader after a reset as opposed to invoking it from the application, since your application might have changed the PLL and WD settings. Once you have taken into account the differences, the SCI loader should work as before.
