1.1.1.4. HPS TAP Controller Is Reset By Cold Reset
Description
The HPS TAP controller should be only be reset by a JTAG reset and should remain active during all other resets. Because of this erratum, the HPS TAP controller is erroneously reset by a cold reset. The HPS JTAG controller will not be visible while HPS is in a cold reset. FPGA JTAG is unaffected.
Workaround
This issue typically will not cause a problem for debugging applications executing in the HPS because you usually do not debug code through a reset. To have access to the HPS JTAG chain, release HPS from cold reset.
Status
Affects: All Arria® V SX and ST devices
Status: No planned fix
