When rebooting P1010, hardware carries out the following.
1.P1010 asserts a HRESET_REQ signal.
2.If HRESET_REQ is asserted, HRESET_B will be asserted in a circuit and the signal will be inputted to P1010.
3.If a HRESET_B signal is asserted, P1010 will negate a HRESET_REQ signal.
It is above.
However, there was a case where it did not operate normally after reboot even if it performs the above.
I attach the file which showed timing.
I think that there is the cause when HRESET_B is asserted immediately, after HRESET_REQ is asserted.
Although regulation of the timing of a HRESET_REQ signal and HRESET_B considers not being written to a datasheet by it, is it right?
Are there any other factors?
