aws_https_client_ek_ra8m1_ep Ethernet connection does not work

Question

Hi, 
 I'm using EK RA8M1 to test out the aws_https_client_ek_ra8m1_ep example which fails to connect to internet, using fsp 5.7.0

Board: 
 EK-RA8M1

Device: 
 R7FA8M1AHECBD

Core: 
 CM85

Toolchain: 
 GCC ARM Embedded

Toolchain Version: 
 13.2.1.arm-13-7

FSP Version: 
 5.7.0

Project Type: 
 Flat

Upon compiling and running the project, the following occurs (J61 jumper is removed)

 But the link never comes up, no matter how long I wait. The same issue occured with fsp 5.6.0 btw. 
 
 Testing with NetX_https_client_ek_ra8m1_ep results i proper connection

 No modification to code was done, examples were just compiled and loaded onto the device J61 was not populated. Any idea what is wrong with aws_https_client_ek_ra8m1_ep example and how to fix it?

Hello asob , 
 Let us apologize for the delayed response on your request due to the big amount of requests we receive per daily basis. 
 I replicated the specific example on FSP 5.7.0 and EK-RA8M1 and I was able to run it without any issues. 
 I used the example provided here in our github repo which has been updated 1 month ago and the example projects are now all in FSP 5.7.0. 
 https://github.com/renesas/ra-fsp-examples/tree/master/example_projects/ek_ra8m1/aws_https_client/aws_https_client_ek_ra8m1_ep 
 I was able as you can see to successfully connect to network. 
 Of course as you mentioned J61 need to be removed so that you use ethernet B: 
 
 And as you can see I was able to connect: 
 
 Also connected successfully to server Adafruit IO by generating my own certificated as descripted on aws_https_client_notes.md. 
 And also managed to perform GET,PUT and POST http requests.

And could see the data on my feed on Adafruit IO server:

Please test the example we provide on git. 
 And let us know if you also successfully run it! 
 Attaching my project also to check what changes you need to do in file user_app.h 
 
 As far it concern account key, certificates and the changes in the name of the APIs.

 Hope it helps.

Hello asob , 
 The specific thread is referring to FTP NetX Client and FTP NetX Server examples. These examples use different stacks and NetX Duo is used for ethernet connectivity. 
 The specific example you are mentioning on this post uses FreeRTOS+TCP stack. 
 I replicated the example again and I was able to connect and send data to server:

The only case that I see what you describe is if I do not remover jumper j61 to enable using ethernet B. 
 
 I have also tested the simple ethernet example from github repo and this example also run successfully.

The board successfully connected to network and obtained an IP address from DCHP server. 
 Test the example attached for simple ethernet connectivity. Also J61 needs to be removed on this example. 
 
 Also could you please specify which IDE are you using? Are you using e2studio? Or other IDE like IAR, Keil MDK etc? 
 In case you are using another IDE than e2studio it is possible that the ethernet is failing due to the fact that the TrustZone boundaries have not been set properly to the device.

Vasanth , 
 Thanks for your request. 
 However we would appreciate it if you could make a new post about your issue in order to help us organize better our work. 
 From the log messages on RTT you shared it looks like you missed the process about generating with OpenSSL the proper certificates and keys to provision and connect to the server succefully, 
 Please read carefully and follow the steps as mentioned on this markdown file: 
 https://github.com/renesas/ra-fsp-examples/blob/master/example_projects/ek_ra6m3/aws_https_client/aws_https_client_ek_ra6m3_ep/aws_https_client_notes.md 
 
 Check the project attached on this thread which has worked for me: RE: Ra6M3 Ethernet Code Issue 
 To see what modifications you should do in user_app.h file inside src folder. 
 
 Thanks and Regards, 
 IK
