Please fix compile! pcm_write + loop/system disk space hung issue in cvi_mpi/modules/audio/Makefile #50
Description
platform enviroment wsl2 Ubuntu24.04.2 LTS + 24.04.2 LTS standalone
Problem:
changes in audio.mk (tinyalsa=no , alsa =yes)
while performing ./build.sh milkv-duo256m-musl-riscv64-sd
compile goes in copy all harddrive files loop after
"[audio insatll>>>>] copy lib to: (xxx)/duo-buildroot-sdk-v2/cvi_mpi/lib"
cp: cannot open '/boot/System.map-6.11.0-21-generic' for reading: Permission denied
etc.. in loop whole drive /
to Fix loop
(As its data hoarder from drive) wipe&restore cvi_mpi dir rm -R ./cvi_mpi&&git checkout -- cvi_mpi
change in cvi_mpi/modules/audio/Makefile :34
PREBUILD_LIBDIR = prebuilt/$(TARGET_MACHINE)
to
PREBUILD_LIBDIR = ./prebuilt/$(TARGET_MACHINE)
Next to compile at all (with tinyalsa =yes as in stock)
( as with alsa = yes compile still fails via absence " No rule to make target 'src/cvi_audio_interface.c', " )
we must add changes to avoid " libcvi_audio.so: undefined reference to `pcm_read' " as in alsa it's snd_pcm_read and anyway we don't have sources of libcvi_audio to recompile )
build/env_setup_milkv.sh:519
function build_pqtool_server()
{(
return; # <-- add this line to skip build pqtoolserver
other changes:
dts file altered to enable SPI pins(default SPI pins are not set ! so /dev/spidev* is useless according to wire RX/TX loop and spi_test) and GC09 display
