Hi all
I have compiled the linux kernel (2.6.29) with EABI option disable so the
expected compiled option is:
-mpcu=apcs-gnu
I have the same compiled option in buildroot and now the amixer and alsamixer
works but aplay and arecord
report this error:
set_params: Channels count non available
Compile the kernel using eabi and oabi compatible give different error.
This is the relevant part of buildroot config
BR2_ARM_TYPE="GENERIC_ARM"
# BR2_ARM_EABI is not set
BR2_ARM_OABI=y
BR2_ARCH="arm"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_ABI="apcs-gnu"
#
# Target options
#
#
# Preset Devices
#
# BR2_TARGET_ARMLTD is not set
BR2_BOARD_NAME="at91sam9260dfc"
BR2_BOARD_PATH="target/device/Atmel/$(BR2_BOARD_NAME)"
and this is the relevant part of the kernel
# CONFIG_AEABI is not set
With other combination I can use playback and record facilites but the mixer
doesn't
work for the size of the parameteres during kernel syscall
Best regards
