Lab 5: SDK Lab Introduction
This lab guides you through the process of adding timer and interrupt controller to an embedded system and writing a software application that utilizes these timer and interrupt controller. The SDK will be used to create and debug the software application.
After completing this lab, you will be able to: Utilize the XPS timer with interrupt controller
- Assign an interrupt handler to the timer
- Develop an interrupt handler function
- Use SDK Debugger to set break points and view the content of variables and memory
You will extend the hardware design created in lab 5 to include an XPS interrupt controller and XPS Timer (see Figure 5-1). You will develop an interrupt handler to count the interrupts generated from the timer. The steps for completing the lab are listed below:
1. Add a timer and interrupt controller
2. Create a SDK software project
3. Write an Interrupt Handler
4. Add a Linker script
5. Verify operation in hardware SDK Lab: www.xilinx.com/university 5-3

For each procedure within a primary step, there are general instructions (indicated by the symbol). These general instructions only provide a broad outline for performing the procedure. Below these general instructions, you will find accompanying step-by-step directions and illustrated figures that provide more detail for performing the procedure. If you feel confident about completing a procedure, you can skip the step-by-step directions and move on to the next general instruction.

Add a Timer and Interrupt Controller Step 1Create a lab5 folder and copy the contents of the lab4 folder into the lab5 folder, or copy the content of the labsolution\lab4 folder into the lab5 folder. Launch Xilinx Platform Studio (XPS) and open the project file.
Create a lab5 folder in the C:\xup\embedded\labs directory and copy the contents from lab4 to lab5, or copy the content of the labsolution\lab4 folder into the lab5 folder → → → → → → → → → → → →
Open XPS by selecting Start → All Programs → Xilinx ISE Design Suite 12 → EDK → Xilinx
Browse to the lab5 directory and open the project system.xmp
Add the XPS timer and XPS Interrupt Controller peripherals to the design from the IP Catalog, and connect them to the system according to the following table. xps_intc_0 instance
Intr timer1 Irq Microblaze_0_INTERRUPT delay instance
CaptureTrig0 net_gnd Interrupt timer1 microblaze_0 instance
Add the XPS Timer/Counter peripheral from the DMA and Timer section of the IP Catalog, check Only One Timer is present option, and change its instance name to delay
Add the XPS Interrupt Controller peripheral from the Clock, Reset, and Interrupt section of the IP Catalog with default settings Connect the timer and interrupt controller as a ‘s’ (slave) device to the PLB bus (see Figure
Figure 5-2. Add and Connect the Interrupt Controller and Timer Peripherals
Select Address tab and click Generate Addresses The generated addresses should look similar to that indicated in the figure below
SDK Lab: www.xilinx.com/university 5-5
Figure 5-3. Generate Addresses for Interrupt Controller and Timer peripherals
- Connect interrupt output port Irq of the xps_intc_0 instance to the MicroBlaze interrupt input port using the microblaze_0_INTERRUPT net
- Click in intr field of xps_intc_0 field to open the Interrupt Connection Dialog. Click on timer1 on left side, and click on sign to add to the Connected Interrupts field (right), and then click OK
SDK Lab: www.xilinx.com/university 5-6
In the Ports section, type in timer1 as the Interrupt port connection of the delay instance, and hit enter Make a new net connection (see Figure 5-4) for the INTERRUPT (external interrupt request) port on the microblaze_0 instance by selecting New Connection from the drop-down box. This will create a net called microblaze_0_INTERRUPT
Figure 5-4. Make a new net connection to connect the MicroBlaze Interrupt port
Connect the interrupt controller and timer as follows (refer to Figure 5-5)

Write an Interrupt Handler
Create the interrupt handler for the XPS timer
Go to where the interrupt handler function has already been stubbed out in the source file (a fast way to do this is to click on the function in the outline view).
Create new local variable for the timer_int_handler function:
unsigned int csr; The first step in creating an XPS timer interrupt handler is to verify that the XPS timer caused the interrupt. This can be determined by looking at the XPS Timer
Control Status Register. Open the API documentation to determine how theControl Status Register works.
In the XPS System Assembly View window, right-click the delay instance and select View PDF
Datasheet to open the data sheet
Go to the Register Description section in the data sheet and study the TCSR0 Register. Notice that bit 23 has the following description:
Indicates that the condition for an interrupt on this timer has occurred. If the timer mode is capture and the timer is enabled, this bit indicates a capture has occurred. If the mode is generate, this bit indicates the counter has rolled over. Must be cleared by writing a 1
0 - No interrupt has occurred 1 - Interrupt has occurred
0 No change in state of T0INT
1 Clear T0INT (clear to ’0’) The level 0 driver for the XPS timer provides two functions that read and write to the Control Status Register. View the timer API doc by right-clicking on the delay instance in the System Assembly View and selecting Driver:tmrctr_v2_00_a View API Documentation. In the API document, click on the File List link at the top of the document, then click on the link labeled xtmrctr_l.h in the file list. This brings up the document on identifiers and the low- level driver functions declared in this header file. Scroll down in the document and click on the link for the XTmrCtr_GetControlStatusReg( ) function to read more about this function. Use this function to determine whether an interrupt has occurred. The following is the pertinent information found in the XPS timer documentation:
XTmrCtr_GetControlStatusReg ( BaseAddress, TmrCtrNumber )
Get the Control Status Register of a timer counter
SDK Lab: www.xilinx.com/university 5-11
SDK Lab: www.xilinx.com/university 5-12 o BaseAddress is the base address of the device. o
TmrCtrNumber is the specific timer counter within the device, a zero-based number, 0 -> (XTC_DEVICE_TIMER_COUNT - 1)
o The value read from the register, a 32-bit value
Add the XTmrCtr_GetControlStatusReg function call to the code with the associated parameters. The resulting 32-bit return value should be stored in the variable csr. csr = XTmrCtr_GetControlStatusReg(baseaddr, 0); Note: Substitute baseaddr with the base address for the delay peripheral. Refer to xparameters.h
Complete the Interrupt handler (see Figure 5-15) according to the steps below
1. Test to see if bit 23 is set by ANDing csr with the XTC_CSR_INT_OCCURED_MASK parameter.
2. Increment a counter if an interrupt was taken.
3. Display the count value by using the LEDs_8Bit peripheral and print the value using xil_printf (same functionality as printf with the exception of floating-point handling) Hint: You may use the XGpio_DiscreteWrite () function
4. Clear the interrupt by using the following function call:
XTmrCtr_SetControlStatusReg(baseaddr, 0, csr);
The completed handler should look like as shown in the next figure
Figure 5-11. Completed Interrupt Handler Code Save the file, this should compile the source successully. Add Linker Script
SDK Lab: www.xilinx.com/university 5-13
Generate the linker script by assigning code section to ilmb and data section to xps_bram. Set heap and stack to 0x400 each.
Right-click lab5 in project view and select Generate Linker Script Set the heap and stack size to 1024 each
Assign Code section to ilmb_cntlr_dlmb_cntlr and Data, Stack and Heap sections to
xps_bram_if_cntlr (this is necessary as each of the memory is too small to hold everything)
