SpletWe are able to reset over PCIe by writing to the PLL Reset register, and we do this all the time. You must do this: Enable MST_PRIV bit in PCIE_PRIORITY_REG from the host (otherwise key below wont be accepted and nothing will happen). Write the proper key value (0x5A69 i think) to the PLL_RSTCNTL register. SpletThis Hot Reset mechanism is the preferred mechanism to issue independent conventional reset to different P-tile endpoints residing in the same component and/or adapter. This …
