SATA on T1040RDB

Question asked by benlad on Aug 5, 2019

After writing the command header/descriptor for the SATA controller it seems I have to wait a long period (in the order of ms) before I can execute the command by updating the SATA_CQR register.  If I do not wait for the period between writing to the command header/descriptor and the SATA_CQR, I get an error in SATA_CER. 


Any ideas?
