I have a dilemma with an Olimex LPC-L2294 board.
The SSEL0 output is connected via external pullup to the CS pin in the SD card slot. SCK0, MISO0, and MOSI0 are also connected to the card slot.
On the LPC2294 if I configure P0.7 as GPIO to drive CS I get no output on the SPI0 pins (other than the CS).
If I configure it as SSEL0 in PINSEL0 then SPI0 produces clock and MOSI. But it also causes the chip to drive SSEL high, with no means for me to pull it down.
Of course I can get no response from a card when CS is high.
Am I correct in assuming the SD card slot on this board is dead by design? Unless I cut the SSEL0 trace and reroute CS to something I have control over while running SPI0.
