I wasn't aware that sprintf() was legal to call from an interrupt
context on vxWorks. Or did I misunderstand the change?
Hello Eric,
No. You did not misunderstand the changes. I was not aware that
sprintf() is
an illegal call from a VxWorks ISR. Now that I look more closely at the
restrictions you pointed out; there is very little allowed from a VxWorks
ISR; e.g., no ANSI string library calls, strcpy(), strlen(), etc.
I guess if I really want an error message sent from an ISR I will have to a
assemble it using stone tools and animal skins.
Thanks for catching this error.
Hello Jens,
I have redone the MAXv ISR error messages using a version of your code.
The latest (unreleased) version is available here;

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

Hello Ron,
but the motor record has not issued negative

here is an extract of the boot messages with drvMAXvdebug=10, while

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 motorR6-4-4

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.
