Hi all,
I am trying to interface a memory card in my qnx system.This will be a
block device.Can I get sample code of block driver
such as devb-eide …I searched cvs/ftp sites of qnx no use ? I am confused
whether it is a block driver or resmgr ?
Also I am trying to develop one utility for formatting that device in fat16
filesystem …Do anyone know the availability of source of mkdosfs utility ?

Thanks & Regards
Scintill

If you have a good business case (from QNX perspective) you may be able
to get source, but otherwise these are not public.

Hi,
Now anyhow i managed to create a block device entry using resource manager.
I would like to create a dosfs over this block device and I would like to
mount this .How would i do this ?
Is there any reference where i can get the source of mkdosfs?
Can some one suggest me , what to add in my resmgr in order to mount it as a
file ?
My aim is interfacing memory device into a qnx system and to store files …

Thanks

if you’ve written a real bock device (one that fits in QNX filesystem
architecture).
mkdosfs should be able to use it. Why use dos for a filesystem, is less
robust then QNX4 filesystem.

Can some one suggest me , what to add in my resmgr in order to mount it as
a
file ?

Hi,
Its not a real block device as you had mentioned .The fact is we dont know
how to do that .
QNX documentation for developing block device driver/resmgr is unclear.
Can you suggest me how do I go about this ?
mkdosfs is not working on my device (The block device which i had created )
mount is not working
The reason I am going for dos is …customer is asking dosfs as he want to
test the device in his windows machine also .
OK where can i get details about QNX4 fs …??
Thanks
