[LS1021A TWR] external trigger signal for ETSEC.

[devasish]

I am using an LS1021A-TWR board and need to provide 1 PPS external trigger signal. 

Referred to 8.7.7.2 External trigger signal from LSSDK 21.08, but I am still not getting the data in fifo. It talks about proper RCW settings to enable this. This is RCW from the bootup logs from the device:

Reset Configuration Word (RCW):
       00000000: 0608000c 00000000 00000000 00000000
       00000010: 30000000 00007900 60040a00 21046000
       00000020: 00000000 00000000 00000000 18000000
       00000030: 00080000 891b7340 00000000 00000000

Can someone please confirm if this is correct. If not what should be the correct RCW configuration and how to update the same. 

Thanks

Hi @devasish 

Please refer to the following bit 422-424 in LS1021 Referance Manual section 4.4.6.1 RCW field definitions, please refer to 010 option.

Please follow QCVS_PBL_User_Guide to set RCW parameter according to your requirement.

Thanks
