CC1352P: Initiate boot

You can refer to chapter 10 in www.ti.com/.../swcu185b.pdf

Hei Carl-Axel,
You should also take a look at this application note: www.ti.com/.../swra466

Thanks, but these answer does not help us. We are making the circuit diagram. We need to know what
pins should have pull-ups and pull-downs at Reset in order to force the chip to initiate flash load.

Hei Carl-Axel,

The information you are after is stated in the very start of chapter 10 in the document YiKai is pointing to.

Fredrik

Hej! You may call me blind, but I have studied SWCU185B , chapter 10, several times. There is no information that answers my questions there. I have also studied SWRA466A without finding the information.

How does the chip get into the boot mode?
What pins need to be asserted at Reset?
Does the JTAG-pins have to be in a certain state?

Best regards,
Carl-Axel

Well, It is all there in 10.1.1 and 10.1.2.

If the device does not have a valid image in flash, it will boot straight to the bootloader. If there is a valid image in the flash you need to make sure the bootloader is enabled and that there is a defined bootloader backdoor pin. If this is the case, and the bootloader backdoor pin is asserted when the device comes out of reset, it will jump to the bootloader.

All configuration is done in CCFG.

Fredrik
