Hi Mohammad,
You could route a clock from the HPS to the fabric, which is done through the HPS block in qsys. This clock is generated from the on SOM 25Mhz oscillator and is PLLed up to 100Mhz by the HPS. The checkbox is called "Enabl... Daniel Vincelette

This doesn't explain why USB isn't coming up though. Your log doesn't show any USB log statements, the most likely reason would be if the USB kernel modules aren't loaded either.

Hi Sandeep,
Are you trying to loop spidev4.0 to spidev4.1? Or are you looping back one of the two devices onto themselves (e.g., SPI4_D0 connected to SPI4_D1 on same SPI channel)?

If you open up the Datasheet and check Table 8 and search for Y13 you should that it is a direct connect to the EDGE connector (I believe pin 117, but you should double check).
There is no other connection.
