Hi,

How many long Xilkernel take to startup with microblaze (System
Clock : 50 MHz).
On my design, the Microblaze need more than 30 second to create the
first thread after xil_kernel_main().

Sounds like you have a large context switch interval configured. Check the
value for the parameter systmr_internal (specified in milliseconds) in the
kernel configuration. Also check if an incorrect value has been provided to
systmr_freq. Assuming these two values are correct, the first context switch
should take around about the time you have specified for systmr_interval.
Note the kernel initialization time is dependent on the numbers you have
configured for the various kernel features like number of
threads/semaphores -- but unless you threw in a huge number there, this
overhead should be negligible.



when I remove verbose mode, xilkernel start-up in less than 1 second.
