I just committed a large change to the hostmot2 driver in CVS TRUNK that
changes how firmware loading is done. Instead of loading the firmware using
bfload before loading the device driver, the driver now handles firmware
loading itself: it fetches the specified firmware from userspace using udev and
programs the FPGA. The "config" modparam was extended to let the user specify
which firmware they want.
Users who install emc2 using the Debian package will find the firmware files in
/lib/firmware/hm2/<BoardType>/.
Users who use Run-In-Place must symlink the hostmot2 firmware directory of
their sandbox(es) into /lib/firmware before this will work:
sudo ln -s $HOME/emc2-sandbox/src/hal/drivers/mesa-hostmot2/firmware
/lib/firmware/hm2
Replace "emc2-sandbox" in the link target with the actual name of the directory
containing your CVS checkout. If you want to have access to the firmwares from
multiple sandboxes, replace "hm2" in the link name with the sandbox names.
To tell the driver which firmware file to load on a specific board, add
something like "firmware=hm2/5i20/SVST8_4.BIT" to the board's config string.
This is all described in the "config modparam" section of the hostmot2(9)
manpage, here:
<http://www.linuxcnc.org/docs/devel/html/man/man9/hostmot2.9.html#config%20modparam>
Sorry for the disruption, i think it's for the best in the long run.
