How to reset an axi4lite peripheral programmatically through a c baremetal application running on MicroBlaze

Hi All,

 

I have an peripheral connected to a MicroBlaze system through axi4_lite. I'd like to reset it through C. 

 

I would expect to be able toggle a memory-mapped register somewhere to accomplish this but unfortunately I can't locate this.

 

I went through the hardware source files and realized that axi4_lite peripherals can't be reset individually but I'm ok with this (i guess) as there's one signal (interconnect_aresetn_i in 13.4\ISE_DS\EDK\hw\XilinxProcessorIPLib\pcores\axi_interconnect_v1_05_a\hdl\verilog\axi_interconnect.v) to affect them all but then I got a bit lost in proc_sys_reset's files.

 

I know the system is reset when you download an application through SDK and that one can actually choose a type of reset (Xilinx Eclipse SDK -> Run -> Run Configurations -> (choose elf) -> Device Initialization Tab) to Entire System or Processor Only or No Reset.

 

Well I'd like to have something similar (a peripheral reset) but while the processor runs. 

 

Running SDK 13.4.

 

Thanks
