CC2640R2F: Difference between flashing through Flash Programmer 2 and Uniflash in case of OAD

Part Number: CC2640R2F
Other Parts Discussed in Thread: UNIFLASH

Hi,

I have an application with support for On-chip OAD built using SimpleLink CC2640R2 SDK version 2_30_00_28 and CCS-8.2.0.0.

The documentation section "Setting up the BLE OAD Environment" instructs to use "Uniflash" as the flash programming tool. Prior to this, we were using "Smart RF Flash Programmer 2".

I am using python tool "hexmerge" to combine the 4 images (BIM, Persistent, Stack, Application) to create production image as said in (https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/682423?CC2640R2F-How-to-combine-onchip-OAD-fourth-file-to-one-file-for-downloading-easily-

Basically, it makes no difference by using Uniflash or "Smart RF Flash Programmer 2".

Hi,

Sometimes i see that the device does not function properly when combined hex is flashed using "Smart RF Flash Programmer 2" especially during OAD(OAD start using OAD reset service)

Is there any settings that "Uniflash" takes care and "Smart RF Flash Programmer 2" does not take care?

For eg.

Thanks,

Arul Christopher

I don’t think so. It’s more likely that there is something wrong with your combined hex file.

In addition to YK's comments, make sure you are using the newest version of the flash programmer (newest one released Jan. 8, 2019).
