7.1i EDK Xilkernel - Xilkernel stops working when external interrupt is faster than the systmr_freq


Keywords: hang, XMK, timer

In my design, the XMK systmr_freq is set to be equal or greater than the opb_timer interrupt frequency. When a task goes to sleep, Xilkernel does not wake the process back up. How can I resolve this issue?


To work around the issue, change the systmr_freq value to be less than the opb_timer interrupt frequency.

This is fixed in the current version of the EDK software. The first version containing this fix is EDK 8.1.
