Details:

Hi there,

This is causing me problems with implementing bit
bashed sysfs gpio on armhf (in this case a beagle bone black and
derivative) i.e. type = "linuxgpio"
attempting to configure GPIO line 45 failed with the error message:
"pin must be in the range 0-31"


Many thanks for all your hard work.

/Andy


THE FIX:
The definition HAVE_LINUX_GPIO is used to set PIN_MAX between either 31
(default) or 255, however it is called HAVE_LINUXGPIO in the rest of the
codebase.

pindefs.h:62
  #ifdef HAVE_LINUX_GPIO
becomes
  #ifdef HAVE_LINUXGPIO



TO REPRODUCE:
I use a custom config file: lwb-avrdude.conf
  programmer
    id    = "keyboard";
    desc  = "Toby Churchill Ltd.  LWB platform, keyboard";
    type  = "linuxgpio";
    reset = ~45;
    sck   = 2;
    mosi  = 3;
    miso  = 5;
    ;


call avrdude thus:
  avrdude -v -p m32 -C ./lwb-avrdude.conf -c keyboard -e

returns:

          System wide configuration file is "./lwb-avrdude.conf"
 avrdude: error at line 5 of ./lwb-avrdude.conf: pin must be in the range
0-31
