Hello,
I use one GP AXI Master Port to extend IO by adding AXI Interconnect IP and AXI GPIO IP. I test AXI GPIO rate, only 2MHz-3MHz.
In SDK, using code below
while(1)
{
XGpio_DiscreteWrite(&LED_Ptr, 1, 0xffffffff);
XGpio_DiscreteWrite(&LED_Ptr, 1, 0x00000000);
}
When I set FCLK_CLK0 100MHZ, GPIO rate is about 2.3MHz.If FCLK_CLK0 200MHZ, GPIO rate is about 3.6MHz.
I think it is too slow. What is the max rate for AXI GPIO? How to config ZYNQ to max AXI GPIO rate? Thanks!
