CC140XP-DESIGN: CC1312R1F3RGZR--Application for Development Tutorial

? ?

Part Number: CC140XP-DESIGN
Other Parts Discussed in Thread: CC1312R

I saw in the manual of CC1312R that there is 352KB of programmable flash memory and 256KB of ROM for storing the protocol stack.
My understanding is that 352KB of flash memory is used for the storage of the applications we write. That 256KB ROM still requires us to develop the RF protocol stack separately.
Should the protocol stack be burned back into the ROM after compilation? This is equivalent to developing applications and burning them to flash memory, as well as developing protocol stacks and burning them back to ROM.
I don't know if my understanding is correct. Please help confirm.
Also, if there are any development tutorials and instruction documents in this regard, could you provide them? Thank you!

Hi,

We have received your post and the investigation will take some time. Thank you for your patience.

Hi,

ROM is read-only memory, it's not possible to write to it after manufacturing. The protocol stack is stored in ROM. If a change is needed, the specific changes are written to flash and the device will no longer be able to use that piece of ROM code. This is handled by TI software and there is no need for the customer to think about this.

That being said, we use very little of the ROM code in newer SDK releases. Both RTOS and protocol stacks run mainly from flash.

I would recommend starting with SimpleLink Academy. Here we have a bunch of trainings on our existing stacks (e.g. TI 15.4-Stack) and propritary RF:
