then output reports are transmitted to a device through the Control endpoint.
No Fix.
Incorrect Inter-Packet Delay on USB interface.
The Inter-Packet Delay (IPD) between two consecutive High-Speed transmit packets
from the USB ports does not meet the USB2.0 Compliant Test Specification of minimum
88 to maximum 192 bit time. As a result, unable to pass and obtain USB2.0 compliant
logo. The IPD is the time between the end of one packet to the start of the subsequent
packet.
Tested Devices that Pass on the Intel
Processors
Devices that connect to the USB interface may not be recognized when using High
Speed mode.
None.
No Fix.
USB 2.0 Device Reset during Bulk Out Transaction
In High Speed mode, the bit stuffing mechanism fails to insert a zero on the seventh bit
position followed by six consecutive ones. As a result, the USB host fails to send the
entire MaxPacketSize, and illegal packets are detected at the device (for example
MDATA and Split Token in BULK OUT transfer). The device will be reset and packets are
re-transmitted.
Failure signature is intermittent. The USB device will be reset in between the
transmission cycles. Eventually the entire data size (or file) will successfully get to the
device. Meaning that the data could be delayed and cause a performance impact.
None.
No Fix.
RX FIFO Overflow Condition Not Properly Captured in the Rx Status
Register
Whenever Rx FIFO overflows, it generates a rx_fifo_error signal to the Receive State
Machine (RSM). The RSM will transit to a state where it will report a status valid for NPE
to read the Rx Status register (via ECP_RdRxSts instruction). During this state, the
state machine fails to capture the rx_fifo_error signal properly and transits back to idle
state. This results in the Rx FIFO overflow condition not properly captured in the Rx
Status Register.
Causes no further packets to be received in the Rx FIFO. The issue is observed only
when TMII co-exist with HSS interface. Will not happen when the NPE runs in standard
MII mode.
Workaround has been implemented in the Intel
Ethernet NPE measures the Rx idle time, and issues Ethernet MAC coprocessor
instruction (ECP_ClearRxError) to flush MAC Rx Engine FIFO to correct the lock-up
