Hi,I use US159-DA16200MEVZ with AT Command.When I tried acceess to AWS s3 use on AT+NWHTC(with presigned URL), DA16200 put "Hard Fault Exception".Presigned URL is long(over 1500 character) URL Data.
AT Command
AT+NWHTC=https://xxxxxxxx....xxxxxxx,get
Debug Message
And, I confirmed same issue with dummy long URL.AT Command
AT+NWHTC=https://aaaaaaa...aaaaaaa,get
When I used dummy short long URL, Hard Fault is not occured.
AT+NWHTC=https://aaaaa,get OK +NWHTCSTATUS:3
Read CA(length = 0) Read Cert(length = 0) Read Privkey(length = 0) [httpc_cb_result_fn:674]httpc_result: 3, received: 0 byte, err: -16
so, I think maybe over DA16200's URL limit size.I want to solve this problem.I would greatly appreciate any feedback, guidance, or suggestions that the Renesas community can provide.
My SDK Information is...

Hi There,Thank you for posting your question online.From the logs you have shared I can see that you are using a quite old SDK version (v3.2.3). Is there a reason you are not using the latest SDK version?We highly recommend to use the latest SDK version v3.2.6 which you can find here:https://www.renesas.com/eu/en/document/sws/da16200-da16600-freertos-sdk-v3260?r=1600096You can find the pre-compiled images here: https://www.renesas.com/eu/en/document/sws/da16200-da16600-freertos-sdk-image-v3260?r=1600096Regarding the issue you are facing with AT+NWHTC:The maximum url string length is 256 bytes. That is why you were facing a Hard Fault Exception.
You should search on the user_http_client.h file and change:
#define HTTPC_MAX_PATH_LEN 256
#define HTTPC_MAX_PATH_LEN (1024 * 2)
// Max size of HTTP Client's request data #define HTTPC_MAX_REQ_DATA (1024 * 4)
// Stack size of HTTP Client #define HTTPC_STACK_SZ (1024 * 6) // Max 10KB
#define TX_PAYLOAD_MAX_SIZE (1024 * 8) // Max 8KB
Hi OV_Renesas,
Thanks for your answer.
I want to try this suggestions but now I'm facing bellow same problem and I can not build SDK version v3.2.6 on windows.
https://community.renesas.com/wireles-connectivity/f/wi-fi/29990/da16200-sdk-3-2-6-unable-to-build
for now, I wait this issue is solved.
Hi There,Thank you for the reply.I will update you here as well when this issue is fixed.Kind Regards,OV_Renesas
Hi There,Apologies for the delay.The issue on SDK v3.2.6 has been fixed.Please refer here: DA16200 SDK 3.2.6 unable to build - Wi-Fi - Wireless Connectivity - Renesas CommunityKind Regards,OV_Renesas
Thanks for your support.
The build now works for me on Windows 11 ver.21H2 and Eclipse 2023-03 (4.27.0)
And I tried to up url string length, so, Hard Fault with url string length is gone.
Thanks a lot!!
and... now I'm facing bellow new 2 issue.
1. ERROR -682 Occured.
When I send AT+NWHTC Continuously, somtimes AT+NWHTC respond ERROR -682.
(maybe this error -> AT_CMD_ERR_NW_HTC_TASK_CREATE_FAIL = -682,)
When this error is responded, do I retry command until "OK HTTP/1.1 200 OK"?
Or, Do I wait any STATUS?
e.g.
AT+NWHTC=https://xxxxx,put,Message1 OK HTTP/1.1 200 OK AT+NWHTC=https://xxxxx,put,Message2 ERROR:-682 +NWHTCSTATUS:0 AT+NWHTC=https://xxxxx,put,Message3 OK HTTP/1.1 200 OK
2. Hard Fault Exception
Maybe, related to the "1. ERROR -682 Occured"
When I send bellow AT+NWHTC, DA16200 put "Hard Fault Exception".
Is there a way to avoid Hard Fault?
AT+NWHTC=https://xxxxxx,put,Message1 OK HTTP/1.1 200 OK AT+NWHTC=https://xxxxxx,get ERROR:-682 +NWHTCSTATUS:0 AT+NWHTC=https://xxxxxx,get OK HTTP/1.1 200 OK [Hard Fault] +NWHTCSTATUS:0 +INIT:DONE,0
I confirmed this issue too with bellow version.
DA16200_IMG_FreeRTOS_ATCMD_QFN_v3.2.6.0_4MB
I would greatly appreciate any feedback, guidance, or suggestions that the Renesas community can provide.
Hi There,Thank you for the reply.Glad you were able to build SDK v3.2.6 and for being able to get rid off the Hard Fault error for the URL string.Regarding the new 2 errors you are facing, let me check on this and I will get back to you as soon as possible.Kind Regards,OV_Renesas
Hi There,Apologies for the delay.Regarding the Error: -682The root cause of this error was that MCU sent the AT+NWHTC command before it had received the +NWHTCSTATUS:0 response.
The normal sequence is like below:1. MCU will send "AT+NWHTC=">">https://xxxxx,put,Message1" command.2. MCU will receive "OK" response.(Then, the MCU can send another command (for instance: AT+VER) except "AT+NWHTC" to DA16200. You cannot send again the AT+NWHTC command because it is still working)3.Finally, if the MCU receives "+NWHTCSTATUS:0" response, then the MCU can send next AT+NWHTC command.Please test after changing the sequence on the MCU side.Regarding the Hard Fault Error:We were not able to reproduce this error after trying multiple times. Can you please clarify if you faced the error -682 and the hard fault error with the official (pre-compiled) binary (DA16200_IMG_FreeRTOS_ATCMD_QFN_v3.2.6.0_4MB) or if it happened with your own custom binary? If it happened with your own custom binary, could you please provide a map file so we can investigate it?Can you also kindly share how many times (how often) are you able to reproduce the hard fault error?Finally, could you please test again after changing the sequence of the MCU? (MCU send the next AT+NWHTC command only after it has received the +NWHTCSTATUS response)Best Regards,OV_Renesas
Thanks your answer!!
I will try your suggestions "Changing the sequence of the MCU".
HI There,Thank you for the reply.Please share any feedback if you faced the Error: -682 and the Hard Fault error after changing the sequence of the MCU.Kind Regards,OV_Renesas
Sorry I mistake log file.I put again.
Thanks your support.
I tried to change sequence (Wait +NWHTCSTATUS Response).
so, Error: -682 was gone. Thanks a lot!!!
But... I faced Hard Fault too.I insert log (with masked private information)

I would greatly appreciate any feedback/suggestions.
Finally, I will answer the following.
> official (pre-compiled) binary (DA16200_IMG_FreeRTOS_ATCMD_QFN_v3.2.6.0_4MB) or if it happened with your own custom binary?
I use official (pre-compiled) binary (DA16200_IMG_FreeRTOS_ATCMD_QFN_v3.2.6.0_4MB).And I changed MQTT TLS buffer size on debug window refer to the bellow.

> how many times (how often) are you able to reproduce the hard fault error?
When I send Https PUT -> Https GET, Hard Fault or ASSERT vPortFree one or the other always occurs.
Hi There,Thank you for the reply and the feedback.I shared the response with our Wi-Fi Team and I will get back to you as soon as possible.Best Regards,OV_Renesas
Hi There,Our Team was able to reproduce the "ASSERT vPortFree 405/406" error (with the DA16200 EVK + Python HTTPS server on Test PC) and are currently looking for the root of cause. We will update you as soon as possible.
Regarding the Hard-Fault error, our team was not able to reproduce it yet. From the logs you have shared, the URL and header information were blocked with "xxxxxx".Could you please provide the test URL and test cert information (temporarily ROOT CA) of yours. We would like to run the exact same test as you did. If the information is confidential, you could raise a private ticket.In order to do that:Go on our Renesas Website and click on the following: A new window should pop-up:Click on Submit a Ticket and fill the forms.Please make sure that on Inquiry Product Category you have inserted the option Wireless Connectivity.Please also add the link of this forum thread on your private ticket so we can track it down. Everything is confidential there and 1on1.If you do not want to share these information at all, we could provide a debug log enabled test binary to narrow down the issue.The best way for us would be to run the same test as you did.Kind Regards,OV_Renesas
I'm looking forward to solve "ASSERT vPortFree 405/406" .
About Hard-Fault error,
It will take time to prepare Test URL.
Becasae I access Cloud Storage use on Presigned URL with limited time, and I change URL every test.
Sorry Please wait.
Hi There,Thank you for the reply and the feedback.We will be waiting for the Test URL and we will update you regarding the Assert Error as soon as possible.Kind Regards,OV_Renesas
Hi There,Apologies for the delay.Please find the attached zip with a patch we created for SDK v3.2.6 in order to fix the ASSERT vPortFree 405 Error , and hopefully the Hard Fault error as well.You will need to replace the file inside the folder path of SDK v3.2.6 as shown in the zip file.Please test it from your side and share any feedback.20230411_assert_and_hardfault_patch.zipKind Regards,OV_Renesas
Thanks your support!
I will try, and share any feedback.
Please wait.
I tried to your patch zip.
So, ASSERT vPortFree 405 Error was gone.
Thanks for your support !!!
And Hard Fault error is not occured at the moment on this patch.
It seems effective against Hard Fault error too.
I use this patch until official version is released.
Best Regards,
Hi There,Thank you for the reply and the feedback.Glad you are no longer facing these errors. I will update you here when the latest version (which includes the patch) will be released. If you found any answer helpful, you can accept it, this way you can help others in the community as well.If you face any other issue, feel free to raise a new ticket.Best Regards,OV_Renesas
