Start-up Xilkernel on Microblaze

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().

Regards,

Yannick

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.
