CC1352R: Failing programming the Bootloader ofCC1352R

user6223499

Part Number: CC1352R
Other Parts Discussed in Thread: UNIFLASH, ,

I can't load the firmware image to CC1352R1 via bootloader using Uniflash.

I have following every step in the document http://www.ti.com/lit/ug/slau799b/slau799b.pdf for 8 Bootloader Programming for SimpleLink CC13xx and CC26xx MCUs (pag. 14).

Step 1: I build project in ccs (unlike the tutorial, I don't see the file ccfg.c):

Step 2: I get the Firmware Image:

Step 3:

I can to flash the image from Uniflash to the CC1352R via XDS110 USB, but can't achieve the same using the UART / BootLoader.

I start by erasing the entire flash from Uniflash's "Settings & Utilities" (Manual Erase, Erase Entire Flash) via XDS110 USB, and then manually select the device as 'CC1352R (BOOTLOADER)' before to loading the image.
Then, I follow the 8.2 in the document slau799b and I set my COM port and Image Valid Address as 0x00000000 for the CCGF from "Settings & Utilities".

When I load Image, the error message I get is:

And if I click "load Image again", I get the error following:

What happen?
How can I solve that?

Which hardware is this and which UART pins are you using?

The hardware is a LAUNCHXL-CC1352R1, and also I have tried my own board which includes a MCU CC1352R1.

I use DIO12 (RXD) and DIO13 (RXD) as UART pins. I have tried it both XDS Application UART and extern UART.

What hardware is this and what UART pins are you using?

I haven't had time to replicate this. Have you tried to use Flash Programmer 2?

I have used Flash Programmer 2 but I haven't succeeded either. Besides, I haven't got tutorial about Flash Programmer 2 for CC1352 bootloader.

What am I doing wrong in UniFlash following the steps of the tutorial?

For Flash Programmer 2:

Go to XDS110 Class... as marked above. This will show unknown. Select the chip you have connected by manually selecting it.

Then browse to the .out/ .hex you want to use and press the "play" button.

This applies if you have an empty flash, if not, you have to use a bootloader backdoor pin.

How do I generate the / .hex?

I only know that the .out is generated by the ccs automatically.

Once I load the .out or .hex, can I reload another updated .out or .hex using only DIO12 (RXD) and DIO13 (RXD) as UART pins? Or do I have to do some configuration so that the micro always starts reading from the bootloader?

Do you need the hex file? If you search online you should be able to find some E2E posts on how to setup CCS to give out the correct hex format.

See for details on the bootloader. You can set up which pin you want as bootloader backdoor in the CCFG.c file

Where do I have to include ccfg.c?
If you check the first post of this E2E post, in the step 1, I build the project in ccs but I don't see ccfg.c file.

I forgot that this project uses syscfg, see screenshot below on where to enable bootloader etc:

Set the Bootloader backdoor DIO pin and the level to what you want to use in your application.

Ok. But my question in this post is to use uniflash. What am I doing wrong? Can you check my steps?

TI__Guru**** 317180 points

Why do you need to use Uniflash when you can do the same in Flash Programmer 2?

0 user6223499 over 4 years ago in reply to TER

Prodigy 80 points

Because there is more documentation of uniflash than Flash Programmer 2.

In a previous question in this post, I also asked how I can generate the .hex with ccs.

Finally, is it possible to "fake" CCFG (or modifying the code generated by the syscfg) so you don't have to use the Bootloader backdoor DIO pin???

Does that mean that the help you get in SmartRF Studio when you press F1 does not cover what you are looking for?

For hex file, this (https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/t/580228 ) is one of multiple posts on E2E that covers this.

Not sure what you mean by: "Finally, is it possible to "fake" CCFG (or modifying the code generated by the syscfg) so you don't have to use the Bootloader backdoor DIO pin???" If you have an empty flash, you don't need to use this option, if you have a flash image , you have to use this option to use the bootloader. Figure 1 in http://www.ti.com/lit/an/swra466c/swra466c.pdf covers this.

In my board I have all the pins busy, for this reason I need to use only the UART pins to program after having a flash image.
Is it possible to reuse the Bootloader backdoor DIO pin for later firmware execution as GPIO?

I believe you can reuse the pin.
