 Posted: Tue May 08, 2012 5:02 pm Post subject: [SOLVED] Arduino e la toolchain di avr |
 |
|
Allo stato attuale delle cose non c'e' modo di ottenere in gentoo una toolchain valida per compilare i progetti di arduino. Benche' la compilazione degli sketch vada a buon fine, sulla scheda le cose non funzionano a dovere (almeno per l'architettura atmel1280, testata dal sottoscritto). Un esempio classico e' il famigerato sketch blink, che ha come risultato il lampeggiamento a frequenza decisamente superiore (colpa della funzione delay()).
Ho provato quindi ad utilizzare la toolchain precompilata della atmel:
http://www.atmel.com/tool/ATMELAVRTOOLCHAIN3_3_2FORLINUX.aspx
...ed ecco che non funziona, appena provo a compilare ottengo questo errore:
| Code: | /home/carlo.caponi/avr-toolchain/bin/avr-gcc -Os -Wall -fno-exceptions -ffunction-sections -fdata-sections -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -mmcu=atmega1280 -DF_CPU=16000000L -DARDUINO=100 -I. -Iutil -Iutility -I/usr/share/arduino-1.0/hardware/arduino/cores/arduino -I/usr/share/arduino-1.0/hardware/arduino/variants/mega/ -c -o .lib//usr/share/arduino-1.0/hardware/arduino/cores/arduino/wiring.c.o /usr/share/arduino-1.0/hardware/arduino/cores/arduino/wiring.c
unexpected reloc type in static binarymake: *** [.lib//usr/share/arduino-1.0/hardware/arduino/cores/arduino/wiring.c.o] Segmentation fault |
Questo e' un grandissimo problema: in futuro verranno utilizzati sempre piu' dispositivi basati su arduino (stampanti 3d ecc.) e l'unica distribuzione su cui non funziona la toolchain avr e' proprio gentoo, sulle altre tutto funziona a dovere.
Potete aiutarmi almeno a far funzionare la toolchain precompilata?

Qui di seguito trascrivo tutta la configurazione necessaria affinché la compilazione vada a buon fine.
Tutti i file di seguito riportati sono contenuti all'interno della cartella "/etc/portage", quindi per cominciare:
Il codice di seguito elencato permette a portage di applicare le patch incluse nella cartella /etc/portage/patches.
Torna molto utile per applicare delle modifiche al pacchetto finale senza dover ogni volta modificare il relativo ebuild.
Da copiare rispettivamente in "/etc/portage/bashrc" e "/etc/portage/env/eclass/epatch":
| cat bashrc: | post_src_prepare() {
if type epatch_user &> /dev/null && type epatch &> /dev/null
then
epatch_user
else
. ${ROOT}etc/portage/env/eclass/epatch
epatch_user
unset epatch
unset epatch_user
fi
} |
| cat /etc/portage/env/eclass/epatch: | # @FUNCTION: eqawarn
# @USAGE: [message]
# @DESCRIPTION:
# Proxy to ewarn for package managers that don't provide eqawarn and use the PM
# implementation if available. Reuses PORTAGE_ELOG_CLASSES as set by the dev
# profile.
if ! declare -F eqawarn >/dev/null ; then
eqawarn() {
has qa ${PORTAGE_ELOG_CLASSES} && ewarn "$@"
:
}
fi
# @FUNCTION: estack_push
# @USAGE: <stack> [items to push]
# @DESCRIPTION:
# Push any number of items onto the specified stack. Pick a name that
# is a valid variable (i.e. stick to alphanumerics), and push as many
# items as you like onto the stack at once.
#
# The following code snippet will echo 5, then 4, then 3, then ...
# @CODE
# estack_push mystack 1 2 3 4 5
# while estack_pop mystack i ; do
# echo "${i}"
# done

}
# @FUNCTION: estack_pop
# @USAGE: <stack> [variable]
# @DESCRIPTION:
# Pop a single item off the specified stack. If a variable is specified,
# the popped item is stored there. If no more items are available, return
# 1, else return 0. See estack_push for more info.
estack_pop() {
[[ $# -eq 0 || $# -gt 2 ]] && die "estack_pop: incorrect # of arguments"
# We use the fugly __estack_xxx var names to avoid collision with
# passing back the return value. If we used "local i" and the
# caller ran `estack_pop ... i`, we'd end up setting the local
# copy of "i" rather than the caller's copy. The __estack_xxx
# garbage is preferable to using $1/$2 everywhere as that is a
# bit harder to read.
local __estack_name="__ESTACK_$1__" ; shift

fi
eval unset ${__estack_name}\[${__estack_i}\]
}
# @FUNCTION: eshopts_push
# @USAGE: [options to `set` or `shopt`]
# @DESCRIPTION:
# Often times code will want to enable a shell option to change code behavior.
# Since changing shell options can easily break other pieces of code (which
# assume the default state), eshopts_push is used to (1) push the current shell
# options onto a stack and (2) pass the specified arguments to set.
#
# If the first argument is '-s' or '-u', we assume you want to call `shopt`
# rather than `set` as there are some options only available via that.
#
# A common example is to disable shell globbing so that special meaning/care
# may be used with variables/arguments to custom functions. That would be:
# @CODE
# eshopts_push -s noglob
# for x in ${foo} ; do
# if ...some check... ; then
# eshopts_pop
# return 0
# fi
# done
# eshopts_pop
# @CODE
eshopts_push() {
if [[ $1 == -[su] ]] ; then
estack_push eshopts "$(shopt -p)"
[[ $# -eq 0 ]] && return 0
shopt "$@" || die "${FUNCNAME}: bad options to shopt: $*"
else
estack_push eshopts $-
[[ $# -eq 0 ]] && return 0
set "$@" || die "${FUNCNAME}: bad options to set: $*"
fi
}
# @FUNCTION: eshopts_pop
# @USAGE:
# @DESCRIPTION:
# Restore the shell options to the state saved with the corresponding
# eshopts_push call. See that function for more details.
eshopts_pop() {
local s
estack_pop eshopts s || die "${FUNCNAME}: unbalanced push"
if [[ ${s} == "shopt -"* ]] ; then
eval "${s}" || die "${FUNCNAME}: sanity: invalid shopt options: ${s}"
else

# @VARIABLE: EPATCH_SUFFIX
# @DESCRIPTION:
# Default extension for patches (do not prefix the period yourself).
EPATCH_SUFFIX="patch.bz2"
# @VARIABLE: EPATCH_OPTS
# @DESCRIPTION:
# Default options for patch:
# @CODE
# -g0 - keep RCS, ClearCase, Perforce and SCCS happy #24571
# --no-backup-if-mismatch - do not leave .orig files behind
# -E - automatically remove empty files
# @CODE

# @VARIABLE: EPATCH_SINGLE_MSG
# @DESCRIPTION:
# Change the printed message for a single patch.

# @DESCRIPTION:
# Change the printed message for multiple patches.
EPATCH_MULTI_MSG="Applying various patches (bugfixes/updates) ..."
# @VARIABLE: EPATCH_FORCE
# @DESCRIPTION:
# Only require patches to match EPATCH_SUFFIX rather than the extended
# arch naming style.
EPATCH_FORCE="no"
# @FUNCTION: epatch
# @USAGE: [patches] [dirs of patches]
# @DESCRIPTION:
# epatch is designed to greatly simplify the application of patches. It can
# process patch files directly, or directories of patches. The patches may be
# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
# the -p option as epatch will automatically attempt -p0 to -p5 until things
# apply successfully.
#
# If you do not specify any options, then epatch will default to the directory
# specified by EPATCH_SOURCE.
#
# When processing directories, epatch will apply all patches that match:
# @CODE
# if ${EPATCH_FORCE} != "yes"
# ??_${ARCH}_foo.${EPATCH_SUFFIX}
# else
# *.${EPATCH_SUFFIX}
# @CODE
# The leading ?? are typically numbers used to force consistent patch ordering.
# The arch field is used to apply patches only for the host architecture with
# the special value of "all" means apply for everyone. Note that using values
# other than "all" is highly discouraged -- you should apply patches all the
# time and let architecture details be detected at configure/compile time.
#
# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
# for patches to apply.
#
# Refer to the other EPATCH_xxx variables for more customization of behavior.

# User patches are intended for quick testing of patches without ebuild

La seconda non è altro che l'eclass eutils ridotta all'osso. Non sarebbe necessaria se tutti i pacchetti facessero l'inherit di eutils, cosa che non avviene.

Inserire le patch del caso nella cartella /etc/portage/patches/categoria/pacchetto.

Uhm...ho provato, ma non si applicano le patch, nonostante abbia istallato le versioni delle ebuild a cui fanno riferimento.
Ma qui il problema non e' riuscire a compilare una toolchain funzionante su gentoo, a fare questo ci sono riuscito. Il fatto e' che l'hex compilato di software come il firmware "Sprinter" o "Marlin", o un semplice "Blink", non funzionano correttamente, in particolare sulla board arduino-mega sulla quale e' montato il processore atmega1280.
Per questo vorrei far funzionare almeno la versione precompilata della toolchain di atmel. Ma, cavolo, funziona su tutte le distribuzioni linux tranne che gentoo! |

| Probabilmente le patch non vengono applicate per via delle tabulazioni trasformate in spazi o errori simili. Le versioni suggerite precedentemente più le patch generano una toolchain funzionante: sicuramente mi sono espresso male, per "compilazione a buon fine" intendevo quella degli sketch da caricare su arduino. Testato personalmente su Arduino Uno e Mega 2560. |

| Con l'aggiornamento a "cross-avr/gcc-4.6.3" la patch "cross-avr/gcc/gcc-005-constructor.patch" non è più necessaria. |
