Hello Jens,
The common code for the old device support record
initialization; "motor_init_record_com()" was not always
passing positive encoder ratio values. This has been a
bug for a long, long time that is now fixed.
I have also conditionally added your fix for sprintf()
not callable from the RTEMS interrupt context to the
MAXv ISR.
Both of these changes will be available, soon, in the
next release.
Thanks for pointing out these problems,
Ron

here is an extract of the boot messages with

This command (ER-180140,52359) does not work for
current firmware versions.
Are you using a really old
version of the motor record?
No, this is the

Re: 2 MAXv problems
Hello Jens
There has been a recent (R6-4 and above) fix to prevent intermittent
MAXv command
errors from occurring when User Units are turned off, but the motor
record has not
issued negative encoder ratio commands for a long time. Are you using a
really old
version of the motor record?

Hi all,
I found, that in recent firmware versions (1.31) of the MAXv cards the
command to set
negative encoder resolutions (e.g. "AX ER-2,3") as used by the MAXv
driver
does not work any more.
Instead a command error is returned and the encoder resolution will
remain
unchanged.
I couldn't find this "new feature" documented anywhere.
