LwIP integration - mapping RTEMS FDs to LwIP ones
Hello Antonio, I have noticed that you have tried to map RTEMS network applications to LwIP. You have tried to use LwIP headers instead of NewLib provided ones. To integrate read, write, close etc. correctly it is necessary to use RTEMS FDs and map them to LwIP ones. See my description in RTEMS Wiki https://devel.rtems.org/wiki/Packages/LWIP I have tried to implement this mapping based on original RETMS network stack cpukit/libnetworking/rtems/rtems_syscall.c file. There is the result https://github.com/ppisa/rtems-devel/blob/master/rtems-omk-template/applwiptest/rtems_lwip_io.c I have been able to run RTEMS provided telnetd over this IP stack replacement on TMS570LS3137. See telned startup fragment at starting lines 58 and 155 of example application https://github.com/ppisa/rtems-devel/blob/master/rtems-omk-template/applwiptest/init.c#L58 Because LwIP sockaddr type can in general differ and AF_XXX and PF_XXX differ between NewLib and LwIP there is implemented layer to translate NewLib application types and defines to from/to LwIP ones https://github.com/ppisa/rtems-devel/blob/master/rtems-omk-template/applwiptest/rtems_lwip_int.h https://github.com/ppisa/rtems-devel/blob/master/rtems-omk-template/applwiptest/rtems_lwip_sysdefs.c I have revised actual sockaddr types and it seems that they should compile to same fields types and offset. So that part of the file is probably not required. I have removed RTEMS provided archives ar d librtemscpu.a in_proto.o ip_fw.o ip_icmp.o ip_input.o \ main_netstats.o main_ping.o rtems_syscall.o \ tcp_debug.o tcp_input.o tcp_output.o tcp_subr.o \ tcp_timer.o tcp_usrreq.o udp_usrreq.o and replaced them by ar r librtemscpu.a rtems_lwip_sysdefs.o rtems_lwip_io.o I have used already described mapping to LwIP https://sourceforge.net/p/ulan/lwip-omk/ci/master/tree/ports/os/rtems/arch/ LwIP stack is our code with OMK build system, probably some simpler RTEMS only build tree can be prepared https://sourceforge.net/p/ulan/lwip-omk/ci/master/tree/ Test application together with links to LwIP has been build from OMK templete https://github.com/ppisa/rtems-devel/tree/master/rtems-omk-template config.target: RTEMS_MAKEFILE_PATH=/opt/rtems5.0/arm-rtems5.0/tms570ls3137_hdk_sdram config.omk: CONFIG_OC_APP_APPLWIPTEST=y CONFIG_OC_APP_APPLWIPTEST_RTEMS_IO=y CONFIG_OC_APP_APPLWIPTEST_TELNETD=y CONFIG_LWIP_LIB=y CONFIG_LWIP_LWIP_IPV4=y #CONFIG_LWIP_LWIP_SNMP=y CONFIG_LWIP_LWIP_ARP=y CONFIG_LWIP_OS_PORT = rtems CONFIG_LWIP_DEVICE_DRIVERS = tms570_emac #lwipots CONFIG_LWIP_STATIC_IP_ADDRESS=0 CONFIG_LWIP_HOST_TMR_INTERVAL=0 #CONFIG_LWIP_DYNAMIC_HTTP_HEADERS=y vypnul jsem ja CONFIG_LWIP_SYS_LIGHTWEIGHT_PROT=1 CONFIG_LWIP_LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT=1 #CONFIG_LWIP_MEMP_OVERFLOW_CHECK=2 #CONFIG_LWIP_MEMP_SANITY_CHECK=y CONFIG_LWIP_MEMP_SEPARATE_POOLS=y CONFIG_LWIP_NO_SYS=0 CONFIG_LWIP_TCPIP_THREAD_PRIO=5 CONFIG_LWIP_TCPIP_THREAD_STACKSIZE=8192 CONFIG_LWIP_MEM_LIBC_MALLOC=0 #CONFIG_LWIP_MBOX_SIZE=4 CONFIG_LWIP_MEM_ALIGNMENT=4 CONFIG_LWIP_MEM_SIZE=(64*1024) CONFIG_LWIP_MEMP_NUM_PBUF=48 CONFIG_LWIP_MEMP_NUM_TCP_PCB=32 CONFIG_LWIP_PBUF_POOL_SIZE=256 CONFIG_LWIP_MEMP_NUM_TCPIP_MSG_INPKT=50 CONFIG_LWIP_MEMP_NUM_TCPIP_MSG_API=30 CONFIG_LWIP_IP_REASSEMBLY=0 CONFIG_LWIP_IP_FRAG=0 CONFIG_LWIP_LWIP_DHCP=1 CONFIG_LWIP_DHCP_DOES_ARP_CHECK=0 CONFIG_LWIP_LWIP_AUTOIP=0 CONFIG_LWIP_TCP_MSS=512 CONFIG_LWIP_TCP_WND=(512*4) CONFIG_LWIP_TCP_SND_BUF=(512*4) CONFIG_LWIP_PBUF_LINK_HLEN=14 CONFIG_LWIP_PBUF_POOL_BUFSIZE=256 CONFIG_LWIP_ETH_PAD_SIZE=0 CONFIG_LWIP_MEMP_NUM_NETCONN=10 CONFIG_LWIP_LWIP_NETCONN=1 CONFIG_LWIP_LWIP_SOCKET=1 CONFIG_LWIP_LWIP_SO_RCVTIMEO=1 CONFIG_LWIP_TCPIP_MBOX_SIZE=100 CONFIG_LWIP_DEFAULT_RAW_RECVMBOX_SIZE=100 CONFIG_LWIP_DEFAULT_UDP_RECVMBOX_SIZE=100 CONFIG_LWIP_DEFAULT_TCP_RECVMBOX_SIZE=100 CONFIG_LWIP_DEFAULT_ACCEPTMBOX_SIZE=100 CONFIG_LWIP_LWIP_STATS_DISPLAY=y CONFIG_LWIP_LWIP_STATS=1 CONFIG_LWIP_MEMP_STATS=y CONFIG_LWIP_MEM_STATS=y #CONFIG_LWIP_ALL_DBG_ON=1 CONFIG_LWIP_LWIP_NETIF_API=1 Best wishes, Pavel Pisa ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
pthread_mutexattr_setrobust/pthread_mutexattr_getrobust didn't recognize by (GCI 2018)
Hi guys,
Currently I am working under a new test suite "psxtmmutexattr01" where all
test cases works with except
"pthread_mutexattr_setrobust/pthread_mutexattr_getrobust".
I had searched on internet that we have to declare a macro test for that
and I had done by giving #define _GNU_SOURCE but seems it doesn't works.
Any resolution ?
Thanks
Himanshu
