Freescale Semiconductor User's Guide Document Number: KSDKLWIPUG Rev. 4, 01/2016 lwIP TCP/IP Stack and Kinetis SDK Integration User’s Guide Contents 1 Overview This document describes how to compile and run the lwIP TCP/IP stack examples. This document also provides the board-specific information related to the jumper and hardware settings. 2 Release Scope 2.1 Hardware Support for TWR-K64F120M and TWR-K65F180M Tower System modules and FRDM-K64F Freescale Freedom Development Platform 3 Requirements for Running lwIP Demos © 2016 Freescale Semiconductor, Inc. 1 Overview....................................................................1 2 Release Scope............................................................ 1 3 Requirements for Running lwIP Demos.... ...............1 4 lwIP code structure.................................................... 2 5 Compiling or Running the lwIP Stack and Demos........................................................................3 6 Revision History......................... .............................. 9 lwIP code structure 3.1 Hardware • • • • • TWR-K64F120M/ Freescale Freedom FRDM-K64F platform TWR-SER and elevator TWR-K65F180M USB cable Ethernet cable 3.2 Software • • • • • • Freescale KSDK release package that includes the lwIP TCP/IP package IAR Embedded Workbench for ARM® version 7.50.0 Keil® μVision® 5 Integrated Development Environment Version 5.17 service pack for Kinetis K60 Kinetis Design Studio IDE Version: 3.0 Makefiles support with GCC revision 4.9-2015-q3-update from ARM Embedded Atollic® TrueSTUDIO® 5.4.0 3.3 Board jumper settings The Ethernet-related jumper settings are described in this document. For other jumper settings, see the board-specific user’s guide. By default, the lwIP stack uses RMII mode. Follow the below hardware configuration: • TWR-K64F120M • J32 1-2: Use the external clock from the CLOCKIN0 to keep the synchronization with the external PHY on TWR-SER Tower System module. • TWR-K65F180M • No jumper specifications. • TWR-SER • J2 3-4: Ethernet PHY Clock Select 50 MHz, RMII mode. Cut off other connections on this jumper. • J3 2-3: Route 50 MHz clock to CLOCKIN0. Cut off other connections on this jumper. • J12 9-10: Ethernet PHY Configuration, pull-up CONFIG0, RMII select. Cut off other connections on this jumper. • Freescale Freedom FRDM-K64F platform • No jumper specifications. 4 lwIP code structure The lwIP code is located in this folder:/middleware/lwip_1.4.1. The lwip folder includes the source code. There are two subfolders in the lwip folder as shown in the figure. lwIP TCP/IP Stack and Kinetis SDK Integration User’s Guide, Rev. 4, 01/2016 2 Freescale Semiconductor, Inc. Compiling or Running the lwIP Stack and Demos Figure 1. lwIP folder structure • src • This subfolder includes the lwIP 1.4.1 source code which can be downloaded from this link: savannah.gnu.org • port • This subfolder includes the adapter files which can make the lwIP stack run on the KSDK and different RTOSes. 5 Compiling or Running the lwIP Stack and Demos 5.1 Step-by-step guide for IAR This section shows how to compile and run demos in IAR. 1. Open the workspace corresponding to different demos and different boards. For example, the lwip_ping_demo.eww on the Freescale Freedom FRDM-K64F Platform under /boards/frdmk64f/demo_apps/lwip/lwip_ping/bm/iar/ or the lwip_ping_demo_freertos.eww on the Freescale Freedom FRDM-K64F platform under /boards/ frdmk64f/demo_apps/lwip/lwip_ping/freertos/iar/. These steps use lwip_ping_demo.eww on FRDM-K64F as an example. Figure 2. Workspace 2.

Click the “Go” button to run the demo. lwIP TCP/IP Stack and Kinetis SDK Integration User’s Guide, Rev. 4, 01/2016 4 Freescale Semiconductor, Inc. Compiling or Running the lwIP Stack and Demos 5.2 Step-by-step guide for Keil This section shows how to compile and run demos in Keil. 1. Open the workspace corresponding to different demos and different boards. For example, the lwip_ping_demo.uvmpw on the Freescale Freedom FRDM-K64F platform under /boards/frdmk64f/demo_apps/lwip/lwip_ping/bm/ mdk/ or the lwip_ping_demo_freertos.uvmpw on the Freescale Freedom FRDM-K64F platform under / boards/frdmk64f/demo_apps/lwip/lwip_ping/freertos/mdk/. These steps take lwip_ping_demo.uvmpw on the Freescale Freedom FRDM-K64F platform for an example. Figure 5. Workspace 2. 3. 4. 5. Build the ksdk_platform_lib library. Build the lwip_ping_demo. Click Start/Stop Debug Session. Wait for the download to finish. Click the “Run” button to run the demo. 5.3 Step-by-step guide for the Kinetis Design Studio IDE and Atollic TrueSTUDIO lwIP TCP/IP Stack and Kinetis SDK Integration User’s Guide, Rev. 4, 01/2016 Freescale Semiconductor, Inc. 5 Compiling or Running the lwIP Stack and Demos This section shows how to compile and run demos in the Kinetis Design Studio IDE. The steps are identical for Atollic TrueSTUDIO. 1. The Kinetis Design Studio doesn’t have a workspace. Create a workspace and import the platform/rtos libraries and the lwIP demos. For example, ksdk_platform_lib under /lib/ksdk_platform_lib/kds/K64F12 and .cproject for lwip_ping_demo on Freescale Freedom FRDM-K64F platform under /boards/frdmk64f/demo_apps/lwip/ lwip_ping/bm/kds/; or lwip_ping_demo_freertos on Freescale Freedom FRDM-K64F platform under / boards/frdmk64f/demo_apps/lwip/lwip_ping/freertos/kds/.

Debug Configurations 4. Click the “Debug” button. Wait for the download to finish. 5. Click the “Resume” button to run the demo. 5.4 Step-by-step guide for ARMGCC and KDSGCC 1. ARMGCC and KDSGCC both use cMake to generate makefiles. Run the batch file (in the Windows® operating system) or sh file (in Linux® operating system) to build projects. These steps use ARMGCC as an example. 2. Change to the demo directory. For example: /boards/frdmk64f/demo_apps/lwip/lwip_ping/bm/armgcc 3. Run build_all.bat to build both debug and release projects. 4. Go to the debug/release directory to download and run the elf file using gdb. 6 Revision History This table summarizes revisions to this document. lwIP TCP/IP Stack and Kinetis SDK Integration User’s Guide, Rev. 4, 01/2016 Freescale Semiconductor, Inc. 9 Revision History Table 1.
