NetXDuo mDNS domain set issue
Hello, My issue is related to:- MCU: STM32H733 Middleware: Azure RTOS Middleware Component: NetxDuo (6.2.0) Addon: mDNS I am using Azure RTOS with NetxDuo, I implemented a secure https server in my device and implemented mDNS which was working very well for me till I required to change domain. I want to add a sub-domain like (myhostname.mysubdomain.local). In documentation it is stated that by default the domain is .local but can be changed using nx_mdns_domain_name_set API Now, I have implemented this API in my code like this: ``` status = nx_mdns_create(&mdns_instance, &ip_instance, &netxduo_packet_pool, MDNS_PRIORITY, mdns_thread_stack, sizeof(mdns_thread_stack), (UCHAR *)hostname, (VOID *)local_service_cache, sizeof(local_service_cache), (VOID *)peer_service_cache, sizeof(peer_service_cache), NX_NULL); if (status != NX_SUCCESS) { Error_Handler(); } status = nx_mdns_domain_name_set(&mdns_instance, "home"); status = nx_mdns_enable(&mdns_instance, PRIMARY_INTERFACE); ``` It returns success and according to the document I must be able to ping hostname.home but thats not the case not matter what I done it will be always accessible through hostname.local I checked the domain name buffer inside mdns_instance, its updated to home but even then changed domain is not accessible. Goal: To be able to add subdomain Bigger Picture: I want to use wild card while generating certificate and keys in alt name and CN so that same certificate can be used in many devices thats why I need subdomain as it allows wild card in *.example.local not in *.local
USBX: hard fault after reading fx_directory_information_get
Hi team, I'm using stm32f746disco and trying to implement USBx as a host with AZURE RTOS. Everything goes well until I want to read the file size using the "fx_directory_information_get" function. The function runs without failure and returns the values correctly, but if I unplug the USB, the MCU goes to a hard fault. Questions: 1) Am I using the right function to read the file size? 2) Does it need to call any other function before or after "fx_directory_information_get" somehow to close or flush the media?
How to tune azure netxduo to receive more incoming connections?
Hello, I am using the stm32h563 processor in my project. I made a TCP Server application using the ethernet connections of this processor and I was able to run it as I wanted. But I saw that it could not connect to another client over the same IP address without breaking the connection with one client. Even though I set the NX_MAX_PHYSICAL_INTERFACES defined value to two, there was no change. Also, in the files I shared, it is said that we can make a tcp server and 2 tcp client connections and open a separate socket for each (1). After some research, I realized that this problem can be solved with lwip + freertos. Below are examples of these solutions. How can I make a similar solution on Azure RTOS Netx side? Our problem with lwip + freertos solved community issue(2) was previously shared and the solution was "By tweaking the options in lwipopts.h, it should be possible to receive more incoming connections: MEMP_NUM_TCP_PCB, MEMP_NUM_TCP_PCB_LISTEN, MEMP_NUM_NUM_NETCONN, etc... " was returned as ". As a similar header you can see the extension(3) under the References header.

NetX Duo and AWS
Hi, I am currently using Azure RTOS on my project. I want to connect my device with AWS(Amazon Web Services). I found some sources but, I did not find any examples on STM32 devices. Is there any examples with NetX Duo on AWS? On the other hand I have found examples with FreeRTOS. Do I have to use FreeRTOS to access all features of AWS? Regards
Configuring Levelx
I am kind of lost about filex vs levelx configuration. My memory is the w25q64jv, it has 8mb being 2048 blocks of 4096 bytes. Configuring levelx: nor_flash->lx_nor_flash_total_blocks =2048; nor_flash->lx_nor_flash_words_per_block =128; What I have understood is Levelx uses 1 sector (512b) for control, so 7 sectors are left for data for each block (4096b). Now I computed the total data sectors available: 7 x 2048 =14336 and have used this amount when formating the media (total_sectors). Is that right?LevelX NandFlash Problem
The page size of nand flash used is 8KB, a block has 128 pages, a total of 10 * 1024 blocks are used, but when _lx_nand_flash_open function is used to open, it is found that the opening fails. According to my code trace, it was found that the LX_NAND_PAGE_TYPE_ERASE_COUNT_TABLE branch in the _lx_nand_flash_open function caused an error when page_index=1. But this value is actually written using the _lx_nand_flash_format function, Because the _lx_nand_flash_metadata_build function gets page_count=2 (page_count= (nand_flash ->) when erasing counts. lx_nand_flash_block_status_table_size + (nand_flash -> lx_nand_flash_bytes_per_page - 1)) / nand_flash -> lx_nand_flash_bytes_per_page;) I would like to ask, does levelX not support such a large Nand-Flash? Or is there something wrong with my configuration?
minor bugs in nx_dns.c
Hi all, working on nx_dns.c versio 6.1.12 I found some minor bugs. In function 3911 _nx_dns_host_resource_data_by_name_get() we have a NX_DNS_QUERY_FAILED 0xA3 /* DNS query failed; no DNS server sent an 'answer' */ return value on most errors, end even if we got a reply. It seems that it is due to line 4052 4052 return(NX_DNS_QUERY_FAILED); while 4052 return(status); would return actual error. You can test this searching a non existing domain name (e.g. goo4gle.com) or setting server address to a non existing dns server (e.g 91.1.1.1). Digging deeper, I found another non optimal return value in function 4888 _nx_dns_response_process() Here we have NX_DNS_SERVER_AUTH_ERROR 0xAC /* Server not able to authenticate answer/authority data*/ for any reply with reply code 0x2, 0x3, 0x6, 0x7, but not alla are errors. Can be reproduced as before with non-existing domain. it comes from line 4039 nad folowing if ((status & NX_DNS_ERROR_MASK) == NX_DNS_ERROR_MASK) { /* Release the source packet. */ nx_packet_release(packet_ptr); return NX_DNS_SERVER_AUTH_ERROR; } Best would be to add in nx_dns.h #define NX_DNS_REPLY_CODE_OK 0xB8 /* base value for reply code management */ #define NX_DNS_REPLY_CODE_FORMERR 0xB9 /* DNS Query Format Error */ #define NX_DNS_REPLY_CODE_SERVFAIL 0xBA /* Server failed to complete the DNS request */ #define NX_DNS_REPLY_CODE_NXDOMAIN 0xBB /* Domain name does not exist */ #define NX_DNS_REPLY_CODE_NOTIMP 0xBC /* Function not implemented */ #define NX_DNS_REPLY_CODE_REFUSED 0xBD /* The server refused to answer for the query */ #define NX_DNS_REPLY_CODE_YXDOMAIN 0xBE /* Name that should not exist, does exist */ #define NX_DNS_REPLY_CODE_XRRSET 0xBF /* RRset that should not exist, does exist */ #define NX_DNS_REPLY_CODE_NOTAUTH 0xE0 /* Server not authoritative for the zone */ #define NX_DNS_REPLY_CODE_NOTZONE 0xE1 /* Name not in zone */ and change 4939 if (((status & NX_DNS_QUERY_MASK) == NX_DNS_RESPONSE_FLAG) && ((status & NX_DNS_RCODE_MASK) != NX_DNS_RCODE_SUCCESS)) { /* Release the source packet. */ nx_packet_release(packet_ptr); return (NX_DNS_REPLY_CODE_OK + (status & NX_DNS_RCODE_MASK)); } This allows to take proper action if required.
