Linux – De1-soc HPS-to-FPGA AXI bridge

I work on DE1-Soc. I am using a linux BSP (linux console) that i found in terasic's website linux image.

I have some questions about the AXI bridge. In fact i would like to send some data from the hps to the fpga through the AXI bridge ( HPS-to-FPGA AXI ) and then use those data by the FPGA. I created a Quartus project based on the DE1-SOC-GHRD. The DE1-SOC-GHRD includes the file soc_system.qsys which includes hps_0 (HPS component). I would like to use the EPCQ to store the fpga configuration (.sof) And sD card for linux and my app.

Can someone give me some advices about how to use the AXI bridge? work to do for the FPGA and work to do for processor?

I am new in Soc, and i found it hard to understand how it works. I read cyclone V handbook but i feel that i missed something and i don't know what.

update:

I used Qsys to generate my hps component ans my system. I created 2 slave component(read and write) ( avalon memory mapped slave) and i can through the lightweight HPS-to-FPGA bridge map the address of the first slave (write) and write data. Also with the second one i can read data from it by the hps. The problem is that the lightweight HPS-to-FPGA bridge has a capacity of 32 bits. So i would like to use the HPS-to-FPGA bridge which has a capacity of 128 bits. I did the same thing that i did for the lightweight. but it doesn't work. I don't know why??

What is the difference between those two bridges? is there something to add (configuration)? I didn't find the base address of the HPS-to-FPGA bridge? where can i find it?

for example: what I did for the lightweight bridge

first:

define HW_REGS_BASE ( ALT_STM_OFST )

define HW_REGS_SPAN ( 0x04000000 )

define HW_REGS_MASK ( HW_REGS_SPAN - 1 )

define WRITE 0x0

define READ 0x10


// lightweight base address

define ALT_LWFPGASLVS_OFST        0xff200000


virtual_base = mmap( NULL, HW_REGS_SPAN, ( PROT_READ | PROT_WRITE ), MAP_SHARED, fd, HW_REGS_BASE );

then:

// address for write

h2f_write=virtual_base + ( ( unsigned long  )( ALT_LWFPGASLVS_OFST + WRITE ) & ( unsigned long)( HW_REGS_MASK ) );

//address for read

h2f_read=virtual_base + ( ( unsigned long  )( ALT_LWFPGASLVS_OFST + READ ) & ( unsigned long)( HW_REGS_MASK ) );
