GEN2

Unexpected Outputs During Boundary Scan

Date Added: 10/18/2002

Description: D[32:60] outputs may behave indeterminately during boundary scan.

Workaround: Reset the device by asserting PORESET while HPE/EE1=0. Alternatively, assert

PORESET throughout boundary scan.

Fix Plan: RevA

SC1

PC Cannot Be Updated in Debug Mode Entered From Asynchronous Interrupt

Date Added: 10/5/2000

Description: When a DEBUG instruction is executed in a static or dynamic delay slot created by

an asynchronous interrupt, the core enters Debug mode, but the PC cannot be updated.

Workaround: In the dynamic case, the debugger can use a status bit in the ESR, which indicates

whether the core entered a debug in a delay slot. Software workarounds are available for all the

static cases. A detailed description was sent by StarCore and can be resent upon request.

SC3

Erroneous Trace Buffer Value

Date Added: 10/5/2000

Description: An erroneous 62-bit value may be written to the trace buffer when the EOnCE is

programmed to write both event counters (ECNT_VAL and ECNT_EXT).

Workaround: None.

CPM2

CAM Access Not Atomic

Date Added: 5/30/2000:

Description: The bus atomicity mechanism for CAM access may not function correctly when

the CPM’s DMA accesses the CAM. This only affects systems in which multiple CPMs will ac-

cess the CAM.

Workaround: None

No CTS Lost Indication with HDLC

Date Added: 5/30/2000

Description: When CTS is deasserted at the end of hdlc frame, (last flag or one bit before) trans-

mission will be aborted. However there is no CTS-LOST indication. There is only abort indica-

tion.

Workaround: None

Data Corruption on SDMA Flyby

Date Added: 5/30/2000

Description: The data of a SDMA write, which follows a SDMA flyby read in the local bus may

be corrupted.

Workaround: None
