X-CUBE-VS4A -- How to pass Amazon ATS certificates?

1.Uncommenting one line in service_asset.c still can't work.

Request a token from Amazon website. It shows token "ANeQCyBUgoyAFxrpfsUJ" in browser.

But my STM32F769I shows below messages: Always can't pass Amazon ATS certificates.

=================================================================

Network : ssl_tls.c:4591 : c04337f4: x509_verify_cert() returned -9984 (-0x2700)

TLS certification error, check the Root CA : EVT_TLS_CERT_VERIFY_FAILED(0)

Open a TLS Connection : EVT_OPEN_TLS(0)

Debug : avs_token_imp.c:462 : could not get token from amazon with code ANeQCyBUgoyAFxrpfsUJ

2.Create new project in developer.amazon.com/avs/, and get new client_id, client_secret, project_id, renew these information has the same error.

3.Check CA in default_amazon_root_ca_raw.c, ROOT CA are the same as listed in https://www.amazontrust.com/repository/, But no "Cross Certificates" and no "Other CAs"

in f/w.

What should I do to fix this issue?

My Sequence is: (have step3 or haven't step3 results the same error)

1.enable the new Amazon ATS certificates by uncommenting this line in service_asset.c

{"default_amazon_root_ca", default_amazon_root_ca, sizeof(default_amazon_root_ca)},

2.Enable Messages in avs_base,h

AVS_TRACE_LVL_DEFAULT = (AVS_TRACE_LVL_ALL)

3.Create a Project in developer.amazon.com, update MY_CLIENT_ID, MY_CLIENT_SECRET_ID, MY_CLIENT_PRODUCT_ID values from "Security Profile > Web" page

Add "http://stvs4a/grant_me" in "Allowed return URLs"

4.Use trueStudio build code, select \Projects\STM32F769I-Discovery\Applications\STVS4A\SW4STM32\STVS4A_BSP_LWIP

Binary file outputs: STM32_AVSdemo_F769.elf

5.Use STM32CubeProgramer:

5-1.Connect Device

5-2.Option:Unlocked DBANK

5-3.Select STM32_AVSdemo_F769.elf, set Verify programming.

5-4.Select Available external loaders:MX25L512G_STM32F769I_DISCO

5-5.Full chip erase

5-6.start programming

6.Plug Network from RJ45, Hardware Reset Device

7.Open PC's browser, enter Device's local ip, log in Amazon, redirects to a token url. rename with the local ip in front of the url

8.Browser shows:Got the Alexa access token : xxxxxxx...

But Message shows

"Network : ssl_tls.c:4587 : 0xc0436874: x509_verify_cert() returned -9984 (-0x2700)"

"TLS certification error, check the Root CA"

Hi,

don't change service_asset.c for the moment and it will connect.

This piece of code was written, based on Amazon message telling that the connection way would be updated mid June. The connection part itself was tested on a test server, but the full use case could not be executed at that time.

Currently the legacy way still works.

We'll work on this evolution and make it work for next release.

Hi,

I remove step1.

A Token is already available

But still get another Error as below:

Make sure you have updated the external flash content and that it doesn't contain anymore the default_amazon_root_ca section

Hi Emmanuel_C,

Yes, I did full chip Erase by STM32CubeProgramer before download firmware.

I use default setting to run Sdk v1.1.1 and v1.1.0, both has the same log, and LCD is always showing "Resolving Amazon..."

I only change clientId, clientSecret, productId, which are get from the project I created in Alexa's developer web site.

Use default clientId, clientSecret, productId has the same result also.

======== Below log with default debug settings, for detail error please refer my previous comment ============

Hi,

Except doing internal and external flash full chip erase.

I also remove codes relative default_amazon_root_ca:

1.service_assets.c -- assets_header_flash_base

2.service_persistent_storage.c -- service_persistent_init_default

After build, no "default_amazon_root_ca" relative codes can be found in output.map.

But still get the same log. LCD also always shows "Resolving Amazon...".

There's an error returned in avs_porting_http2_client_connect > http2ClientConnect.

How should I do to fix this error?

Thank you.

Hi,

Has anything been resolved with this issue?

I am having a similar issue.

I followed the steps in the response above and I still am getting a certificate error.

I have tried it with and without the default certificate commented out.
