Part Number: DK-TM4C129X
I am using the base code as an example provided in ti rtos (though it is for another board) for establishing a https client on my target.
When the board it connected to ethernet, and i run the code, i get the error that host is not resolved.
To test, I tried to connect curl to my cloud server, and got the same error host is not resolved. Then i set the proxy settings for curl and i am able to connect curl to cloud via proxy tunnel.
Now i want to do the same on my target, ie to set proxy.
I am not able to find much documents or example on this. Can you please help, and guide me in the right direction.
Thanks a lot

I was able to set the proxy settings on this board.
I was able to do http get command from the target successfully.
My next concern is regarding the httpS client. I understand that the wolfssl has to be downloaded separately, build and then linked to my project(pls correct if i'm wrong). But the wiki page doesn't mention my board in Supported targets and products section.
Is it possible to create a HTTPS client on dk-tm4c129x??
Please guide me on this

I was trying to build the wolfssl as mentioned in the wiki page: http://processors.wiki.ti.com/index.php/Using_wolfSSL_with_TI-RTOS#Build_Instructions
my wolfssl version is 3.11.0
but when i build it i get the following error regarding aes file
i understand that i have to change the configuration in the settings.h.
can me you tell me what is the correct configuration that has to be changed for ti rtos
this is how my products.mak file looks

a.vmy wolfssl version is 3.11.0
Our WolfSSL support for Tiva is limited to WolfSSL v3.9.6w. You can download that version (GPL licensed) of WolfSSL from their github.
Hope this helps.

I am stiil facing the same error after trying with version 3.9.6.w of wolfssl.
Can u suggest the correct configuration of the products.mak file and the solution to overcome this error.
i was able build the wolfssl correctly following this link: https://github.com/wolfSSL/wolfssl-examples/tree/master/tirtos_ccs_examples
My board is DK-TM4C129X
there is no example which i can use directly from resource explorer.
i have followed the above link and was able to build a https get project for my board without error.
when i run this i get an error
httpsTask: TLS create failed
i understand while using wolfssl on this board needs the certificate to be saved as a string.
uint8_t ca ="line1" "line2" "line3" "and so on";
tlsParams.ca = ca;//storage;
tlsParams.calen = strlen((const char*)ca);//strlen(SL_SSL_CA_CERT_FILE_NAME);
tls = TLS_create(TLS_METHOD_CLIENT_TLSV1_2, &tlsParams, NULL);
UARTprintf("httpsTask: TLS create failed");
cli.tls = tls;
is this the right format??
i had entered the certificate as such: my certificate geo trust golbal ca
uint8_t ca ="MIIDVDCCAjygAwIBAgIDAjRWMA0GCSqGSIb3DQEBBQUAMEIxCzAJBgNVBAYTAlVT\
with back slash at the end
i have added start sntp function now, but it waits forever on the semhandle semaphore.
if i comment this semaphore pend out i get current time as Current time: Thu Jan 1 00:00:00 1970
later code crashes at tls create.
this is my code format
#define NTP_HOSTNAME "126.96.36.199"#define NTP_PORT "123"#define NTP_SERVERS 3#define NTP_SERVERS_SIZE (NTP_SERVERS * sizeof(struct sockaddr_in))
my final aim is to connect to google firebase cloud.
Any help is appreciated
thanks a lot
