The program assigns the following settings to the board if DHCP is disabled or DHCP request times out: IP Address: 192.168.1.10 Netmask : 255.255.255.0 Gateway : 192.168.1.1 MAC address: 00:0a:35:00:01:02 These settings can be changed in the file main.c. The main tftp server logic is present in the file tftp_server.c. Running the tftp server example ------------------------------- To connect and test the tftp server. Run tftp client on host machine: $ tftp 192.168.1.10 $ tftp > put sample1.txt Sent 60 bytes in 0.0 seconds Logs on board: TFTP WRQ (write request): sample1.txt TFTP_WRQ: Transfer completed lwIP tftp client ---------------- Files to be included: lwip_example_i2c_access.c lwip_example_iic_phyreset.c lwip_example_platform.c lwip_example_platform.h lwip_example_platform_config.h lwip_example_platform_mb.c lwip_example_platform_zynq.c lwip_example_platform_zynqmp.c lwip_example_sfp.c lwip_example_si5324.c lwip_example_tftp_platform_fs.c lwip_example_tftp_platform_fs.h lwip_example_tftp_client.c lwip_example_tftpclient_common.h lwip_example_tftpclient_main.c The lwIP tftp client application gets/puts files from/to tftp server running on host machine. The program assigns the following settings to the board if DHCP is disabled or DHCP request times out: IP Address: 192.168.1.10 Netmask : 255.255.255.0 Gateway : 192.168.1.1 MAC address: 00:0a:35:00:01:02 These settings can be changed in the file main.c. The main tftp client logic is present in the file tftp_client.c. TFTP client application will put and get 3 files from TFTP server(default: 10.10.70.101). TFTP server ip can be changed from tftp_common.h. Running the tftp client example ------------------------------- To test the tftp client application tftp server should be running on the host machine. Log on board: TFTP_WRQ: tftp get sample1.txt TFTP_WRQ: Transfer completed TFTP_WRQ: tftp get sample2.txt TFTP_WRQ: Transfer completed TFTP_WRQ: tftp get sample3.txt TFTP_WRQ: Transfer completed TFTP_RRQ: tftp get sample1.txt TFTP_RRQ: Transfer completed TFTP_RRQ: tftp get sample2.txt TFTP_RRQ: Transfer completed TFTP_RRQ: tftp get sample3.txt TFTP_RRQ: Transfer completed lwIP Webserver -------------- Files to be included: lwip_example_i2c_access.c lwip_example_iic_phyreset.c lwip_example_platform.c lwip_example_platform.h lwip_example_platform_config.h lwip_example_platform_mb.c lwip_example_platform_zynq.c lwip_example_platform_zynqmp.c lwip_example_sfp.c lwip_example_si5324.c lwip_example_ws_platform_fs.c lwip_example_tftp_platform_fs.h lwip_example_web_utils.c lwip_example_ws_http_response.c lwip_example_webserver.c lwip_example_webserver.h lwip_example_ws_main.c The lwIP webserver application starts a webserver at port 80. By default, the program assigns the following settings to the board: IP Address : 192.168.1.10 Netmask : 255.255.255.0 Gateway : 192.168.1.1 MAC address: 00:0a:35:00:01:02 These settings can be changed in the file main.c. The main webserver logic is present in the file webserver.c. platform.c implements certain processor and platform dependent functions. Setting RAMFS parameters ------------------------ As the webserver uses RAM based FAT FS to store webpages, it's important to set correct RAMFS parameters according to your h/w. By default, xilffs library takes following value for ramfs_size and ramfs_start_addr: ramfs_size - 3145728 ramfs_start_addr - 0x10000000 These values should work for most Zynq and ZynqMP solutions, but are likely to be different for MicroBlaze. Please set appropriate parameters in xilffs section of MSS file for your h/w, if they should be different. Creating FAT image on Linux --------------------------- This requires root (sudo) access on the Linux host Following commands can be used on terminal to create FAT image to be used with webserver application: # create image file of 3MB dd if=/dev/zero of=example.img bs=512 count=6144 # format image with FAT /sbin/mkfs.vfat example.img # mount it mkdir /tmp/fs sudo mount -t vfat -o loop,rw example.img /tmp/fs/ # copy your webpages sudo cp -r webpages_dir/* /tmp/fs/ sudo umount /tmp/fs Running the webserver example ----------------------------- The application expects webpages to be stored in RAM based FAT FS. Please tune RAM FS start address and size according to the h/w design and size of webpages in MSS file. Please load FAT FS image file in the RAM at the same address as the one specified in the MSS file while running the application. To connect and test the webserver, download the program and FAT image file on the board, and then run the program. The server can be accessed using the URL - http://; e.g. http://192.168.1.10 lwIP IGMP --------- Files to be included: lwip_example_i2c_access.c lwip_example_iic_phyreset.c lwip_example_platform.c lwip_example_platform.h lwip_example_platform_config.h lwip_example_platform_mb.c lwip_example_platform_zynq.c lwip_example_platform_zynqmp.c lwip_example_sfp.c lwip_example_si5324.c lwip_example_igmp_app.c lwip_example_igmp_app.h lwip_example_igmp_main.c Requires igmp options(LWIP_IGMP) in lwip library configuration parameters. The lwIP IGMP application joins a default multicast group of 224.10.10.3. Any data sent to this Multicast IP address and default 5001 port, will be accepted. Once IGMP_MULTICAST_RXPKT_COUNT (defined in igmp_app.h) packets are received, then application will send single multicast packet and leave multicast group. Following IGMP Mulitcast options can be changed in file igmp_app.h, 1) IGMP_MULTICAST_IP_ADDRESS 2) IGMP_MULTICAST_PORT 3) IGMP_MULTICAST_RXPKT_COUNT If LWIP_DHCP enabled then board should get IP address from DHCP server. If DHCP timeout happens or LWIP_DHCP disabled then, the program assigns the following IP settings to the board: IP Address: 192.168.1.10 Netmask : 255.255.255.0 Gateway : 192.168.1.1 MAC address: 00:0a:35:00:01:02 These settings can be changed in the file main.c. The main IGMP logic is present in the file igmp_app.c. Running the IGMP example ------------------------ To connect and test the IGMP, download and run the program on the board, and then issue the following command from your host machine: $ iperf -c 224.10.10.3 -t 2 -u -b 1M -B FreeRTOS lwIP tftp server ------------------------- Files to be included: lwip_example_iic_phyreset.c lwip_example_platform_config.h freertos_lwip_example_tftp_platform_fs.c freertos_lwip_example_tftp_platform_fs.h freertos_lwip_example_tftp_server.c freertos_lwip_example_tftpserver_common.h freertos_lwip_example_tftpserver_main.c The Free
