[cbm4linux-users] cbm4linux problem

[<ds...@pu...>]

Hi.

I've been trying to get my 1541 drive working with cbm4linux recently, and
I'm having a very annoying problem. What's most annoying about it is that
I have no idea what's causing it - cbm4linux, my drive or my cable.

Basically, when I boot up and load parport_pc and cbm, I get the following
output in my kernel log:
cbm_init: using passive (XM1541) cable (auto), irq 7
cbm: resetting devices
cbm: sleeping 5 seconds...

So far, so good. I then run cbmctrl detect, and it shows my 1541 as device 8.

But when I try to write to it (d64copy foo.d64 8), there's several things
that seem to happen at random. Either I get the following output:
[Fatal] could not identify device
[Warning] Unknown drive, assuming 1541
[Fatal] drive 08 (1541): 99, DRIVER ERROR,00,00

Or it starts, and gives back write errors for every sector, with the drive
not actually doing anything.

Sometimes, however, it seems to work just fine, but then after a few
sectors gives write errors.

Anyone have any ideas? Hardware malfunction is quite possible, as this
drive does sometimes behave strangely. The cable also could be suspect -
it's an XM1541 I made. I've checked it several times, and can see nothing
wrong with it, but you never know.

Any help would be greatly appreciated! Thank you.
