AXI Master example fails memory access

100mokhtar
100mokhtar over 13 years ago

Hi all,

I created a peripheral with CIP ( AXI4 burst capable high-throughput memory mapped interface), I connected the slave of peripheral to the master GP2 of PS and its Master to the HP0 of PS (64 bits). I choose the option to generate the ISE project and template driver files of peripheral with quite the default options (added software reset). So I keep evrything by default, But when I run the SW application an error appear to me :

*****************************
* User Peripheral Self Test
******************************

User logic slave module test...
   - slave register write/read passed

Soft reset test...
   - write 0x0000000A to software reset register
   - soft reset passed

User logic master module test...
   - source buffer address is 0x00102F80
   - destination buffer address is 0x00103000
   - initialize the source buffer bytes with a pattern
   - initialize the destination buffer bytes to zero
   - start user logic master module to receive word from the source
   - transfer completed
   - start user logic master module to send word to the destination
   - transfer completed
   - destination buffer byte 1 is different from the source buffer
   - master module data transfer failed

I try to disable the cache but the same error appear to me.

Any help please???

Mokhtar.

    Yes, I disabled the cache:
        void Xil_DCacheDisable(void);
    or

      void Xil_L1ICacheDisable(void);
    - master module data transfer failed
    That is means there is no transfer happened
    And I found the same error
