Code Description
0 Reserved
1 When a change of the RX SDI mode is requested that requires changing the RXCDR_CFG2 attribute in the GT transceiver, the UHD-SDI control module attempts to do a DRP write cycle to change that attribute. If the UHD-SDI DRP control module detected a mismatch between the written RXCDR_CFG2 value and its actual content after retries, the sequence fails with this failure code.
2 When a change of the RX SDI mode is requested that requires changing the RXOUT_DIV attribute in the GT transceiver, the UHD-SDI control module attempts to do a DRP write cycle to change that attribute. If the UHD-SDI DRP control module detected a mismatch between the written RXCDR_CFG2 value and its actual content after retries, the sequence fails with this failure code.
3 The gtwiz_reset_rx_datapath_in port of the GT Wizard IP is asserted after completing a series for DRP and GT port during a dynamic change to reset the GT RX portion. If the gtwiz_reset_rx_done_out port of GT Wizard IP failed to assert after retries, the sequence fails with this failure code.
4 When a change of the RX SDI mode is requested that requires changing the RXDATA_WIDTH attribute in the GT transceiver, the UHD-SDI control module attempts to do a DRP write cycle to change that attribute. If the UHD-SDI DRP control module detected a mismatch between the written RXDATA_WIDTH value and its actual content after retries, the sequence fails with this failure code.
5 When a change of the RX SDI mode is requested that requires changing the RXINT_DATAWIDTH attribute in the GT transceiver, the UHD-SDI control module attempts to do a DRP write cycle to change that attribute. If the UHD-SDI DRP control module detected a mismatch between the written RXINT_DATAWIDTH value and its actual content after retries, the sequence fails with this failure code.
