Part Number:AWR1243BOOST
I have carried out following experiments to transfer MIPI CSI2 data from TI 1xxx chip
1. AR1443 connected with MIPI CSI2 receiver with appropriate termination - Carried out successfully and able to analyze data.
MIPI CSI2 LP states is as expected and Voltage swing [VOH - VOL] is 1.2V
2. AWR1243 connected with same MIPI CSI2 receiver with same termination [Configured with DEVPACK & Radar Studio Tool ] - Unable to receive and analyze data
MIPI CSI2 LP states is as expected but Voltage swing [VOH - VOL] is 0.8V
For CSI configuration,
AR1443 : setHSI CSI command is used, SDK - 0.8
AWR1243 : On DataConfig tab we select
Data path - CSI, Packet 0 ADC_ONLY, Packet 1 - Suppress Packet, Virtual channel No - 0,0
Lane Clock - DDR clock, Data rate 300Mbps [As clock of 1443 CSI output we measured it as 150MHz]
CSI2 Lane Configuration: Unchanged
On ContStream - StreamEnable
Query:
Why the voltage swing for 1243 is 0.8V despite of using the same receiver termination?
How can we see Linked List Configuration Parameters for 1243?
Please guide whether the configuration is correct or we need to set some other parameters as well.
Thanks,
Andy
