I know microblaze support fast interrupt mode with 3 signal: interrupt, interrupt_address and interrupt_ack. So I connect these signal to 3 corresspond signal in my interrupt controller. I have some question here:
1)If i wanna use fast interrupt, so interrupt handler has a format below, right...
I wanna access in a register like a bit. Example :
u32 ISR = Xil_In32(TMR1_BASEADDR + bTmrTCSR0);
if (ISR[8] == 1)
function();
else
fuction1();
But this error "subscripted value is neither array nor pointer nor vector" happen.
aruipksni,
all signal have connected. now I build application interrupt handle for my SoPC. I have some problem here. I have 1 interrupt interrupt from AXI timer.
Main program: just a simple shift 8 led.
MyINTC_Initialize(): Initialize my interrupt controller ( enable...
PORT INTERRUPT = Interrupt, DIR = I, LEVEL = HIGH, SIGIS = INTERRUPT##, BUS = INTERRUPT
PORT INTERRUPT_ADDRESS = Interrupt_Address, DIR = I, VEC = [0:31]##, BUS = INTERRUPT
PORT INTERRUPT_ACK = Interrupt_Ack, DIR = O, VEC = [0:1]##, BUS = INTERRUPT
so I should uncomment it,right ???
With...
I have just connect 3 signal interrupt, interrupt_address, interrupt_ack invidiual, so DRC not warning driven to GND any more
WARNING:EDK:4180 - PORT: tdi_in, CONNECTOR: bscan_tdi - No driver found. Port will be driven to GND -...
I think APB interface in my interrupt, It's ok when I use code below
void MyINTC_Initialize()
{
Xil_Out8(sysclr, 0x01);
Xil_Out8(ier, 0xff);
Xil_Out8(iscra, 0x55);
Xil_Out8(iscrb, 0x55);
Xil_Out8(ipra, 0x10);
Xil_Out8(iprb, 0x32);
Xil_Out8(iprc, 0x54);
Xil_Out8(iprd, 0x76)...
indeed. I conntect to all interrupt source "ext_event" ,"nmi_event" and "irq_in". any problem about this ??? Besides, I edit it in mpid file right??
But still no ID interrupt na. You can see my xparameter.h below
Attachment:
/*******************************************************************...
I do it just like you say but in xparameter.h still not ID for interrupt source
## Ports
PORT req_int = Interrupt, DIR = O, SIGIS = INTERRUPT, BUS = INTERRUPT, PERMIT = BASE_USER, DESC = 'Interrupt Request Output'
PORT vect_int = Interrupt_Address, DIR = O, VEC = [31:0], VEC = [31:0], ENDIAN =...
If I insert the line just like you write above, it mean have a priority for each interrupt source[L to H], right ??? But I don't want this priority because my interrupt controller support "programmable priority" for each interrupt already, you have a way what to ignore this ?? because i just...
I don't sure PORT Interrupt just you write above, its a interrupt input source or output to MicroBlaze ???
This is mpd file of my interrupt controller:
BEGIN intc
## Peripheral Options
OPTION IPTYPE = PERIPHERAL
OPTION IMP_NETLIST = TRUE
OPTION HDL = MIXED
OPTION IP_GROUP = USER
