The L4 Watchdog Module Address Map is not exact in the hps.h

Hello, 

I would like to use header in my application using Altera Cyclone V. 

In the Cyclone V Hard Processor System Technical Reference Manual I can find this information about the Watchdog: 

L4 Watchdog Module Address Map 

Registers in the L4 Watchdog module 

Module Instance Base Address 

l4wd0 0xFFD02000 

l4wd1 0xFFD03000 

But in the following header file the address does not correspond: 

7 816:# define ALT_L4WD0_OFST 0xffd00200  

7 859:# define ALT_L4WD1_OFST 0xffd00300  

Is that the good header file? 

What can I do? 

Thanks for your help 

Jerome

Hi, 

 

I'm not sure why you are seeing different values, but It should be like 

@6546:# define ALT_L4WD0_OFST 0xffd02000 @6589:# define ALT_L4WD1_OFST 0xffd03000  

I have checked the file from the "Quartus installation directory\ip\FreeRTOSv10.0.1\FreeRTOS\Demo\CORTEX_A9_Cyclone_V_SoC_DK\Altera_Code\HardwareLibrary\include\socal\hps.h" 

If you are facing the same issue try reinstalling Quartus. 

 

Let me know if you need any further assistance.

Hi, 

Thanks for your reply. 

I don’t use the same directory; the hps file is in that directory: 

C:\intelFPGA_pro\18.0\embedded\ip\altera\hps\altera_hps\hwlib\include\soca10\hps.h 

I cannot find your directory, can you give me a link to install Quartus free including the freeRTOS directory? 

Thanks for your help.
