Good hello,<br> I have a PCMCIA CAM card on EN50221 standard.<br> The card is interfaced to BCM7324 on EBI lines.<br> Board detects the card,and it has to get initialised through proper sequence .The sequence follows :set Reset bit and Poll for Ready bit in command Register <br>
The offset of Command Register is 0x1<br> the processor address pins and CAM address pins are interfaced as follows<br> Processor CAM Card<br> A3<------------------------>A2_CAM<br> A2<-------------------------->A1_CAM<br>
A1<-------------------------->A0_CAM<br> ........<br> processor does not show A0 .I suppose this is for even address alignement.<br>CAM memory map for command Register is <br>A0_CAM=1<br>A1_CAM=0<br><br> Hence to configure 0x1 offset(Command Register) i do<br>
CHIP_SELECT=0x1A000000<br> *(ioremap(CHIP_SELECT+2,0x4) =value.<br><br> I think CHIP_SELECT+2 should select A0_CAM=1 ;<br> Am I right on this?<br><br> But when i read the command register value i don,t get correct value.<br>
<br> Can someone please tell me if i select the registers properly as <br> written above ? Or please suggest me something else to be done .<br><br>Warm Regards,<br> Vivian<br><br><br> <br> <br> <br>
