Hi all,
I'm working with MPC855T Processor based target board, I'm trying to support
3CXM556 Megahertz Cellular Modem PC Card , I could able to detetect the card
like...
root@192.168.6.6:/# cardctl ident
Socket 0:
product info: "3Com", "3CXM/3CCM556", "Megahertz 56K Cell/Telephony Modem"
manfid: 0x0101, 0x0034
function: 2 (serial)
root@192.168.6.6:/# cardctl config
Socket 0:
Vcc 5.0V Vpp1 0.0V Vpp2 0.0V
interface type is "memory and I/O"
irq 9 [exclusive] [level]
speaker output is enabled
function 0:
config base 0x0300
option 0x60 status 0x08
io 0x03f8-0x03ff [8bit]
But I couldn't communicate with the card, If i send Modem string from
Minicom I'm not getting any responce from the target , Do i need to change
anything related to MPC855T .
Please help me out.
Thanks and Regards,
Prabhakar Kalasnai

Are the drivers being loaded? This done by cardmgr, and it uses the
/etc/pcmcia/ scripts (network.options, memory.options). If you got a
consistent response from cardctl for
#cardctl ident
Or something like that, your pcmcia interface should be working.
Remember that pcmcia drivers should be loaded by cardmgr, not by a simple
insmod. This is because the driver waits for a CARD_INSERT event, which's
generated by cardmgr.

This will not work with unmodified kernel sources; for the modem you
need the standard serial driver which cannot coexist with the MPC8xx
serial driver (they use the same major numbers).
We implemented this some time ago; see the linux-2.4 module on our
CVS server and search "drivers/char/serial.c" for "MPC8xx_UART".

Wolfgang,
We have got the kernel from MontaVista (linux-2.4.2_hhl20) , I think it
might be a modified kernel source.
I could run some other card called "Billiontin 56 KBPS FAX/MODEM card" for
same kernel and same Target board.
I'm getting problem with this specific card(3CXM556 Megahertz Cellular Modem
PC Card) only.
My card is detected by the kernel and kernel could assign irq 9. The problem
is when I send modem string through Minicom it's not responging.
what could be the problem ?
Best regards,
Prabhakar

Leonardo,
The drivers being loaded with cardmgr only and it uses /etc/pcmcia/scripts
only.
I could detect correctly there is no problem in it, the problem is when i
send modem string through Minicom , I'm not getting "OK" responce from the
card.
It might be the problem read/write into the card. But i don't know how ?
Best Regards,
Prabhakar

Maybe you should contact MV support, then.
