To whom it may concern,
We're working on binging up a T2081 based board, derived from the T1042RDB and T2080RDB. cfg_rcw_src pins are set for SD card boot.
Observing the Pins shows an active clock, and command sequences sent on CMD, however DAT0 is constantly held low. DAT[1:3] are all held high.
The same SD card when used in the T2080RDB shows activity on DAT0, other pins read the same our board.
What might be going on?
Thanks for your help,
