I tried to connect the two memory card devices by connecting it on ssp port of lpc2148, i have access to memory cards when i enabling them one by one but i can't access memory card device 1 when i'm enabling the both devices on file configuration.c I connected both card's MOSI,MISO,SCLK on same ssp port of lpc2148,i'm using GPIO port 0.20 for ss of one memory card and GPIO port 0.07 of another memory card
I used example program for SD_file in MCB2140 ,i modified spi driver with ss pin as gpio port 0.07 for second device,for first device i'm using inbuilt spi driver
NOTE: I can access both device separately on same bus,i can't able to access them at a time
PLS give some idea
