LAUNCHXL-CC2640R2: Procedure to Program Simple Peripheral on-chip?

NathanS said:

The BIM and stack projects need to be flashed before the app project.

Because of this Procedure 1, will not work. I tried Procedure 1 again and my CC2640R2 Launchpad can not be seen at SensorTag App. This is On-Chip OAD configuration simple peripheral

But why for CC2650 Launchpad when I program the hex files of sensortag_cc2650lp_app, sensortag_cc2650lp_hex, and bim_extflash using SmartRF Flash Programmer 2, it works without problems after reset. My CC2650 launchpad can be seen at SensorTag App. This is Off-Chip OAD configuration.

Hi,

It is possible that it could work with the app getting flashed first, depending on the memory mapping. In general though, the app should always be flashed after the stack and bim.

I will try this later. But this is the comparison I did with simple peripheral for CC2650 Launchpad and Simple Peripheral for CC2640R2 Launchpad.

Procedure 4. CC2650 Launchpad detected at SensorTag App.

1. Program hex files of simple_peripheral_cc2650lp_app and simple_peripheral_cc2650lp_stack to CC2650 Launchpad using SmartRF Flash Programmer 2.

Procedure 5. CC2640R2 Launchpad not detected at SensorTag App.

1. Program hex files of simple_peripheral_cc2640r2lp_app and simple_peripheral_cc2640r2lp_stack to CC2640R2 Launchpad using SmartRF Flash Programmer 2

Procedure 6. CC2640R2 Launchpad detected at SensorTag App. Able to turn on LEDS and detect key press.

1. Program hex files of project_zero_cc2640r2lp_app and project_zero_cc2640r2lp_stack to CC2640R2 Launchpad using SmartRF Flash Programmer 2

With these test comparison there is something wrong with your simple_peripheral_cc2640r2lp_app and simple_peripheral_cc2640r2lp_stack. 

Since my current product development requires on-chip OAD I need to know the correct procedure to program the hex files of simple_peripheral_cc2640r2lp_app_oad_onchip, stack, and bim using SmartRF Flash Programmer 2.

Procedure 7. CC2640R2 Launchpad not detected at SensorTag App.

1. Program hex files of simple_peripheral_cc2640r2lp_stack and bim_oad_onchip_cc2640r2lp_bim using SmartRF Flash Programmer 2.
2. Program hex file of simple_peripheral_cc2640r2lp_app_oad_onchip using SmartRF Flash Programmer 2.

Procedure 8. CC2640R2 Launchpad not detected at SensorTag App.

1. CCS->Debug simple_peripheral_cc2640r2lp_stack to load program.
2. CCS->Debug bim_oad_onchip_cc2640r2lp_bim to load program.
3. CCS->Debug simple_peripheral_cc2640r2lp_app_oad_onchip.

Please, clarify the procedure. I also used oad_target_cc2640r2lp_stack hex files but still same result. The alternate way is to use Project Zero as base for product development and then add on-chip OAD. But, from my experience with Project Zero at CC2650 Launchpad, adding just one service causes error. I hope the same will not happen with Project Zero for CC2640R2 Launchpad.

This is caused by programming hex files of simple_peripheral_cc2640r2lp_app and simple_peripheral_cc2640r2lp_stack from C:\ti\simplelink_cc2640r2_sdk_1_00_00_22_copy

CC2640R2 Launchpad detected at SensorTag App if programming hex files of simple_peripheral_cc2640r2lp_app and simple_peripheral_cc2640r2lp_stack from C:\ti\simplelink_cc2640r2_sdk_1_00_00_22

Hi,

As long as you flash the device with bim and the stack project before the app, procedure 1 does work. Make sure you are using the default sdk and try a mass erase of the device first if you still don't see it advertising.

I tried Procedure 1 more than 10 times now and it does not work. I tried also flashing the bim and stack project first and then the app and it does not work. Your engineer can duplicate this at TI side.

Procedure 1: CC2640R2 Launchpad not detected at Sensortag App.

1. Program hex files of simple_peripheral_cc2640r2lp_app_oad_onchip, simple_peripheral_cc2640r2lp_stack, bim_oad_onchip_cc2640r2lp_bim using Smart RF Flash Programmer 2.

What works is Procedure 9. The difference is Procedure 1 uses simple_peripheral_cc2640r2lp_app_oad_onchip and Procedure 9 uses simple_peripheral_cc2640r2lp_app.

Procedure 9: CC2640R2 Launchpad detected at Sensortag App.

1. Program hex files of simple_peripheral_cc2640r2lp_app, simple_peripheral_cc2640r2lp_stack, bim_oad_onchip_cc2640r2lp_bim using Smart RF Flash Programmer 2.

Hi NathanS,

I have done the On-Chip OAD Guide several times and it works. But, I am at software development stage and On-Chip OAD Guide Procedure requires too many steps and the OAD takes some time to finish.

So, now my work flow for software development stage is do Procedure 9 and do Procedure 1 at the last part to test On-Chip OAD.

Thanks for your time.
