CC3200: SSL demo : error (-456) Bad CA File.

Hi all,

I tried the SSL demo, but I am always getting the (-456) error : Bad CA File.
Actually, I am not sure that I have flashed the right certificate or maybe it was an invalid format of certificate.

I am using SDK_1.2.0 and ServicePack_1.0.1.6-2.7.0.0.

Here is the code for setting up the socket and some instruction from SSL() demo:

#define APPLICATION_NAME        "SSL"
#define APPLICATION_VERSION     "1.1.1"

#define SERVER_NAME                "www.google.com"
#define GOOGLE_DST_PORT             443

#define SL_SSL_CA_CERT_FILE_NAME        "/cert/testcacert.der"

#define DATE                13    /* Current Date */
#define MONTH               11     /* Month 1-12 */
#define YEAR                2019  /* Current year */
#define HOUR                10    /* Time - hours */
#define MINUTE              26    /* Time - minutes */
#define SECOND              0     /* Time - seconds */

I downloaded the CA certificate like this way (from windows 10 machine):

Then, I loaded the file using UniFlash:

Thanks.
