The following lists the re-transmit
configuration requirements:
- Software must program
re-transmit related registers before enabling CSI_RX_IF to send data.
- In CSI_RX_IF to CSI_TX_IF
loopback needs to have the same mode on both CSI_RX_IF and CSI_TX_IF
controllers(single, dual, quad). Cannot mix for example dual on CSI_RX_IF
and single on CSI_TX_IF.
- Update CSI_TX_IF_RETRANS_CNTL
for virtual channel desired to be transmitted on Stream2/3.
- Enable CSI_TX_IF to send out
data (Only supports RAW formats)
- Data type
select(CSI_TX_IF_DT0_CFG - CSI_TX_IF_DT7_CFG) for CSI_TX_IF are driven by
bottom 3 bits of datatype from CSI_RX_IF. CSI_RX_IF has the true data type.
Software will need to program the appropriate configuration registers based
on this.
