@Spiro
Many thanks so far, will use 4x1N5819
-->Please by careful with the diodes for the XM1541 cable, use only recommended ones

could be something wrong with my deb setup, as /sbin is not searched
$ /sbin/modprobe cbm
modprobe: ERROR: could not insert 'cbm': Operation not permitted

$ id
....100(users),...

$ cat /etc/udev/rules.d/45-opencbm-xa1541.rules
ACTION!="add", GOTO="opencbm_plugin_xa1541_rules_end"
# xa1541/xm1541 parallel port driver
KERNEL=="cbm", GROUP="users", MODE="0664"

LABEL="opencbm_plugin_xa1541_rules_end"

/sbin/modprobe cbm still requires root privileges

perhaps need to rebuild initrd.img ?

by running /sbin/depmod manually we got entries in

4.19.0-8-686-pae$ grep cbm modules.alias
alias char-major-10-177 cbm
alias opencbm cbm

and
4.19.0-8-686-pae$ grep cbm modules.dep
kernel/drivers/char/cbm.ko: kernel/drivers/parport/parport.ko

$ find /lib/ -iname cbm.ko
/lib/modules/4.19.0-8-686-pae/kernel/drivers/char/cbm.ko

/sbin/depmod on the so are incmod, modrobe

depmod was not run during install as it needs be given /sbin path explicitly as system binary
...
see above

modprobe looks inside /lib/modules/4.19.0-8-686-pae/ by default

--> actually no physical connection yet, just testing to load module, taking a long time to load

This is normal without a cable. The driver tries to reset a floppy. It resets it and waits for the reaction of the floppy. If there is none connected, it will stay there until a timeout occurs ("cbm: quitting because of timeout")

But why is cbm.ko missing at the right location? What does find /lib/ -iname cbm.ko show?

depmod should be in the Debian package named 'kmod'.

Please by careful with the diodes for the XM1541 cable, use only recommended ones as written on http://sta.c64.org/xm1541.html and http://sta.c64.org/xm1541c.html.

@Spiro, I plan to build XA1541 one, is just four diodes.

It is VIA chipset.

@Tomas, are you really using an XA1541 or XM1541 cable? That is, you have a parallel port on your machine that is connected via ISA bus? PCI might work, USB will definitely not work!

If this is right, then the following applies:
First, it would be good to have a complete build log. In your case, I assume that you might be missing the linux kernel headers for your machine. Without them, xa1541 cannot be build.

What Linux system are you using?

Hi,
New to CBM scene, just getting started with C64 & 1541.

make -f LINUX/Makefile opencbm plugin-xa1541
builds but says nothing to be done for plugin-xa1541

make -f LINUX/Makefile install install-plugin-xa1541
...
install -m 755 ..//LINUX/plugin_helper_tools /usr/local/bin/opencbm_plugin_helper_tools
mark that there is no default plugin yet.
..//LINUX/plugin_helper_tools setdefaultplugin "/etc" 00opencbm.conf ""
------ setting new default to: ''.
...

/sbin/modprobe cbm
/sbin/insmod cbm
no such file or directory

find -name cbm.o
./opencbm/compat/cbm.o
./opencbm/lib/cbm.o

Seems I ma missing xa1541 plugin?
Many thanks
Tomas

Thank you for pointing out the omission. I just added v0.4.99.103 to the files section.

0.4.99.99 is not the latest version. The latest version, to date that is 0/4/99/103, (sources) can be found on Guthub: https://github.com/OpenCBM/OpenCBM

The binary Windows download link for this version is https://spiro.trikaliotis.net/download/opencbm-0.4.99.103/opencbm-0.4.99.103.zip

Just for any confused newcomers ;)
