Can you please share the application that you run?
I cannot share the application, because for me i throw this IP to waste and programmed one for myself in the meantime !
But i think it is a bug, so you should look for it.
I will target that to one of our evaluation boards and see where it is going wrong.
Simply connect the QuadSPI as a single SPI in standard mode. Then connect MOSI to MISO. No Flash to read or write. I already
described this in the first post.
It's not a loopback. Can you please point to the reference where it runs a loopback?
As explained above i used the example : xspi_intr_example.c ( see below)
[...]
// Run loopback test only in case of standard SPI mode.
if (SpiInstancePtr->SpiMode != XSP_STANDARD_MODE) {
return XST_SUCCESS;
}
// Connect the Spi device to the interrupt subsystem such that
// interrupts can occur. This function is application specific.
Status = SpiSetupIntrSystem(IntcInstancePtr,SpiInstancePtr,SpiIntrId);
if (Status != XST_SUCCESS) {
return XST_FAILURE;
}
/*
* Setup the handler for the SPI that will be called from the interrupt
* context when an SPI status occurs, specify a pointer to the SPI
* driver instance as the callback reference so the handler is able to
* access the instance data.
*/
XSpi_SetStatusHandler(SpiInstancePtr, SpiInstancePtr,
(XSpi_StatusHandler) SpiIntrHandler);
/*
* Set the Spi device as a master and in loopback mode.
*/
Status = XSpi_SetOptions(SpiInstancePtr, XSP_MASTER_OPTION | XSP_LOOPBACK_OPTION);
if (Status != XST_SUCCESS) {
return XST_FAILURE;
}

But as i explained above, it doesn't work without loopback, and as i further explained above, everything works i even get an interrupt, but the received data is alway 0. . I looks like the input pin i not lead back to the IP.
