CI as card reader via PCMCIA card reader

[misiozol]

Is it possible to write software (firmware) so it will support this idea ? PCMCIA->CF , so it will be possible to use it as flash drive ?

 

[alez]

The CI slot and the PCMCIA slot have the same pinout but different function, the CI slot is directly connected to DVB decoder, is not possible to use CI slot with a PCMCIA CF adapter

You can try to insert your PCMCIA adapter and do a dmesg command and post the output text, but it's very difficult, as alez wrote, to make it works.

hope it will help

Yes.

It help but confirm my theory: in these type of slots can be only inserted PCMCIA Common Interfaces devices.

 

[misiozol]

So there is no hope the idea is dead ? or maybe there is still light in the tunnel in some distant future ? , there is no as well command cardctl which would show devices under PCMCIA but there is no such command ,like there would be no drivers is it ?

I think that is no possbility to use PCMCIA standard devices into CI slots because these slots are connected directly to CPU and are been detected as Common Interfaces slots and not standard PCMCIA ports.

So it's hardware problem that is not allowing use CI as PCMCIA reader? or is there a chance to write driver so cpu will se this as normal PCMCIA slot ?

It's not allowed because CI slots are linked to CI part of CPU.

@misiozol

It is a commonon problem on all DVB receiver, CI slot is NOT a PCMCIA standard slot

 

[misiozol]

So idea is dead

I didn't understand if the CI is connected directly to CPU or to DVB decoder....

If the CPU can talk to CI, why the system won't be able to see the slots as \dev\cmx*?
And is possible an hardware mod to the wiring of the slot?

The CPU implementation and the mainboard design can be different from one model to another.
I've seen the datasheet of Vu+Duo CPU and i see the direct connection of CI slots with the CPU.
This situation is common of most Broadcom CPUs.

The question about /dev entries for CI slots is simple: drivers don't create these entries

Commonly in STB receivers the CPU is also the DVB decoder

Thank you for the info, i'm still a newbie in STB architecture...
