I am trying to customized sci bootloader pins.

In the Reference manual, it says I can customized sci bootloader pins. But how to do it ?

    Hello,

    Thanks for your question! The full steps for configuring the sci mode pins are shown in chapter 4.6.7.2 (SCI Boot Mode). Please follow all steps in this section, along with Figure 4-5. Overview of SCI Boot Function. Also required is chapter 4.3 (Device Boot Modes). That chapter gives the overview of what is needed to be done.

    Reviewing those will give you a full view of the steps needed to change boot pins.

    To answer your second question, the pins shown are the only ones available for SCI boot. Other pins cannot be configured for SCI boot.

    Regards,

    Thanks your reply. Actually still hard to find how to change the variables. I did see in the document, which varible should be changed, I am not very familar with code composer and TI's chip. Is there any example to show how to do that ?

    Hi Zong,

    Our C2000Ware example "boot_ex2_customBootConfig.c" (found in C2000Ware_VERSION#\driverlib\f28004x\examples\boot) would provide an excellent starting point! The other examples in this directory (examples\boot) will also be very helpful for learning this, but please be careful as some will program OTP and OTP changes are permanent.

    To get more familiar with CCS and TI's chips, here are a few suggestions for where to start:

    To get familiar with the chip and code composer studio rapidly, I would highly suggest walking through the C2000™ F28004x Microcontroller Workshop, which provides an excellent overview of how the device works, how to use code composer studio, and how to start your first program. By the end of this, you'll know all the basics and be very familiar with CCS!

    From there, I would then look at the C2000Ware examples mentioned above.

    After these, you'll have a great understanding of the device!

    Let me know if you have any other questions.

    Regards,

    Vince
