Hello,

I trying to repeat a DropBox OTA demo.
I was make all as described in

I made Dropbox App and OTA_R2_MCU_FLASH directory inside

I recompile all and add correct CA certificate into firmware.

But, when I start OTA (by button pressing) I got next errors:

I think that Launchpad can't found image inside DropBox. I'm not sure about path and file name.
Can you make some comments here?

Hi Vladimir,

Please try nesting the folder another level deep as in this post:

e2e.ti.com/.../2200951

Please let me know if this fixes your error.

Sincerely,
Bryan Kahler

I added another one level of deep in apps directory. Now deepest path looks like:

www.dropbox.com/.../OTA_ARM/OTA_R2_MCU_FLASH/OTA_R2_MCU_FLASH
I placed my image 20170908163645_CC3220SF_OTA.tar in each folder:

www.dropbox.com/home/Apps/OTA_ARM/OTA_R2_MCU_FLASH/OTA_R2_MCU_FLASH
www.dropbox.com/home/Apps/OTA_ARM/OTA_R2_MCU_FLASH
www.dropbox.com/home/Apps/OTA_ARM

But I still have the same errors (see original post).

I think I understand what's going wrong.
I can't use OTA_R2_MCU_FLASH as application name. Because it can be only one OTA_R2_MCU_FLASH on DropBox servers. So, when I renamed application name to OTA_R3_MCU_FLASH i got different errors:

I made some debug and complete the quest.

Try to use next command to check image.tar availability from PC:

curl -X POST content.dropboxapi.com/.../download --header "Authorization: Bearer INSERT_TOKEN_HERE" --header "Dropbox-API-Arg:{\"path\":\"/OTA_R3_MCU_FLASH/20170908163645_CC3220SF_OTA.tar\"}" --output 1.tar

If all's good you'll receive something like this:

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  130k  100  130k    0     0  44373      0  0:00:03  0:00:03 --:--:-- 42872

In other case you got some errors.

it's need to be pointed that solution for last issue in my reproduction was described in . You should use Uniflash 4.1

Dear Vladimir -
if you see Section 3.2 of this guide:

dev.ti.com/.../Over_The_Air_Update_Guide.html

you will see the dummy certificate for this is located in this folder: C:\ti\simplelink_cc32xx_sdk_1_50_00_06\tools\cc32xx_tools\ota-example-cert

this is used to test that this is working in your applicaiton, but not for use in "real life"

then you can buy the certificate from the vendor, for your production use:
for example ==> www.digicert.com/.../order-1.php

How to get rid of this problem..I am stuck in this stage.

Hello Dwitam,

You can download CA root certificate from official repository certs.godaddy.com/repository
You should check that file in correct format (der) and corresponding filename.
