AT91SAM9263 Errata - Revision “A” Parts
AT91SAM9263 Preliminary
2D Graphic Controller
AC97
BMS
Bus Matrix
CAN
Polygon Fill Function
Bad Management of Endianess Conversion
BMS Does Not Have Correct State
Problem with Locked Transfers
Low Power Mode and Error Frame
Low Power Mode and Pending Transmit Messages
Refer to
Polygon fill function is not functional.
Problem Fix/Workaround
None.
When the transfer size is not a multiple of bytes, the Endianess is incorrect.
Problem Fix/Workaround
None.
The AT91SAM9263 device samples the BMS signal on the rising edge of proc_nreset (refer to
RSTC) and so one slow clock cycle after the NRST rising edge. NRST cannot be used to isolate
BMS (multiplexed with AC97_RX) at reset.
Problem Fix/Workaround
None.
Locked transfers are not correctly handled by the Bus Matrix and can lead to a system freeze-
up.
This does not concern ARM locked transfers.
Problem Fix/Workaround
Avoid other Bus Matrix masters locked transfers.
If the Low Power Mode is activated while the CAN is generating an error frame, this error frame
may be shortened.
Problem Fix/Workaround
None
No pending transmit messages may be sent once the CAN Controller enters Low-power Mode.
