Hi!

I want to load program with communication pins(GPIOs 29 28) instead of JTAG.

Do I call boot roam on sci boot? or Do I call sci boot function on flash?

Regards

Do you mean branch to flash from Reset? There is a boot to flash boot mode option, just as there is an SCI bootloader option. Please see the TRM.

Do you mean branch to flash from the SCI flash kernel. This is done automatically by the software we provide.

Thank you, and have a good day.

TRM stands for technical reference manual. We have documents which describe the boot ROM.

How do you intend to communicate to the device whether to run the flash application or perform a firmware update? The information needs to get there somehow. What is your software design?

How will your application know when to branch to SCI boot?

This is the fundamental question. And unless you provide some more information and sufficiently formulate your question I will not be able to help you.

Please close this thread if you have no more questions.
