3.5.2. Error Reporting
Parameter |
Value |
Default Value |
Description |
---|---|---|---|
Advanced error reporting (AER) |
On/Off |
Off |
When On, enables the Advanced Error Reporting (AER) capability. |
ECRC checking |
On/Off |
Off |
When On, enables ECRC checking. Sets the read-only value of the ECRC check capable bit in the Advanced Error Capabilities and Control Register. This parameter requires you to enable the AER capability. |
ECRC generation |
On/Off |
Off |
When On, enables ECRC generation capability. Sets the read-only value of the ECRC generation capable bit in the Advanced Error Capabilities and Control Register. This parameter requires you to enable the AER capability. |
Enable ECRC forwarding on the Avalon-ST interface | On/Off | Off |
When On, enables ECRC forwarding to the Application Layer. On the Avalon-ST RX path, the incoming TLP contains the ECRC dword(1) and the TD bit is set if an ECRC exists. On the transmit the TLP from the Application Layer must contain the ECRC dword and have the TD bit set. |
Track RX completion buffer overflow on the Avalon- ST interface | On/Off | Off |
When On, the core includes the rxfx_cplbuf_ovf output status signal to track the RX posted completion buffer overflow status |
