Some basic bootloader questions:
I am trying to design a board with the tms570LC43x IC, and I would like to be able to flash it using the second serial port sciREG2.
I have looked at http://processors.wiki.ti.com/index.php/TMS570_Hercules_MCU_Bootloader and understand that when boot loading one should pull GIO_A7 and then the boot loader code kicks in.
Could a technician cable be made that pulls that line when connected, and a second cable for operational use be made that does not?
I'm looking to build in a boot loader to my project and found SaftyMCU_Bootloater projects, but they do not have one for the LC43x.
Can one of the examples be used (LS04x, LS12x and LS31x are provided)?
Is the bootloader code loaded separately (prior to) from the actual project?
If I load a customized loader on sciREG2, my assumption is that the working Code Composer load will not work as it uses sciREG1. Is that correct or can a configuration be installed that will allow either?
How does the Code Composer initiate the load? Is the reset line pulled some how through the USB ?
