SIMPLELINK-CC2640R2-SDK: v2.20.00.49 Off-chip OAD not working. BTool/OAD Target says OAD Download successful, but new image is not loaded.

Part Number: SIMPLELINK-CC2640R2-SDK
Other Parts Discussed in Thread: CC2640R2F

EDIT: It's not just my OAD distributor code, even the Out-of-the-box simple peripheral off-chip OAD demo provided with the v2.20.00.49 SDK doesn't work with my set-up. Would be helpful if someone confirms that they see the same issue. I have no problems with the on-chip OAD demo.

Hi,

This is my set-up:

1. 2x LAUNCHXL- CC2640R2

2. OAD Downloader/Distributor (written by me)

3. OAD Target (the simple peripheral off-chip OAD example without any modifications)

4. OAD Image used for testing: Just the output *_oad.bin file generated by the build. The ONLY difference from the example simple peripheral off-chip OAD example is the Software Version.

5. BleStack project (NOT ble5)

6. IDE: IAR 8.20

I have implemented an OAD Distributor which transfers a firmware image to the OAD target. The image is downloaded successfully, image is enabled, and the OAD target responds with FLASH_SUCCESS, which indicates that the image has been validated AND saved successfully to external Flash AND the meta-header has been written as well.

But, the newly loaded image is not loaded, even after a power-off/on reset. The BIM seems to find the meta-header successfully, but the CRC check on the entire image fails. Is there something I'm doing wrong?? Similar result when I use BTool. Is there something I'm missing? Maybe in the way the binary is generated maybe?

Thanks for your help!

If you try with with original simple_peripheral_oad_offchip example to work with BTool, does it work?

I just tried that, it doesn't work either. Here's my jumper config.

Why do you remove those jumpers on RESET, TMS, TCK, TDI, TDO, and SWO? And, what does the ribbon cable connect to?

I just got the board like that. I'm not really familiar with this dev board, will put them back on, and test it again. The ribbon cable is just tied to XDS used to flash the image.

LAUNCHXL- CC2640R2F embedded XDS110 on it and you just need to put those jumpers on RESET, TMS, TCK, TDI, TDO, and SWO back to make it work. You don't have to connect external XDS 110 debugger from ribbon cable.

Adding the jumpers didn't help either. Still the same

Do you try original simple_peripheral_oad_offchip example to work with BTool?

0 Sanjay over 5 years ago in reply to YiKai Chen

Prodigy 200 points

Yes, I'm using the original example with BTool. BTool says "OAD Download Successful", but new image doesn't load.

Which SDK version do you use?

0 Sanjay over 5 years ago in reply to YiKai Chen

v2.20.00.49

Try to refer to dev.ti.com/.../performing-an-oad.html and test from scratch again.

Hi,

Have you checked out our OAD user’s guide?

Hi,

I did look at the documentation. Out-of-the-box OAD on-chip works for me, but the off-chip still doesn't work. I'm using IAR to compile, if that changes anything.

This is my setup, again,

Blestack project

SDK v2.20.00.49.

IDE: IAR 8.20

Board: 2x LAUNCHXL CC2640R2

Thanks,

Sanjay

I just tested the 1.4 SDK's ble5stack off-chip OAD demo with my set-up. That works, too.

Can someone please confirm that the 2.20.00.49 SDK does indeed have a problem?

Thanks,

Sanjay

The latest CC2640R2 SDK is 2.30.00.28 and I would suggest you to try it instead of struggling on 2.20.00.49 SDK.

0 YiKai Chen over 5 years ago

Guru 735475 points

For your reference, I had a project based on SDK 2.20.00.49 and the OTA works fine. We will do porting to 2.30.00.28 and expect OTA would work too.

0 Sanjay over 5 years ago in reply to YiKai Chen

Thanks, it works for me now, too. I'm not 100% sure why, but when I remove the RESET pin jumper the OAD doesn't reset correctly after a power on/off reset.
