AT91SAM9G45 Errata
DDRSDRC: DDR2 Multi-port Read Optimization
ECC: Computation with a 1 clock cycle long NRD/NWE pulse
ROM Code: SAM-BA
AT91SAM9G45-ES ROM Code Replacement
Read optimization does not work for the multi-port DDR2. This feature is enabled by default in
the DDRSDRC_HS register at offset 0x2C in the DDRSDRC user interface.
Read optimization must be disabled by software by setting the DIS_ANTICIP_READ bit.
If the SMC is programmed with NRD/NWE pulse length equal to 1 clock cycle, HECC cannot
compute the parity.
It is recommended to program SMC with a value superior to 1.
The connection through USB to the SAM-BA monitor does not work.
Use JTAG or serial port to communicate with SAM-BA monitor.
