Test to read files from the elf image and a USB. Configure file system.
Hello Genode community,
I'm working on porting an application on Genode where I need to upload
files from the elf image and from a storage device , such as a USB .
Currently I can read the file of the USB using the libffat library and
the server/ffat_fs, but in this case I can not load the file from elf
image. I think the problem lies in the configuration of < vfs > .
Any ideas to solve my problem ?
Thank you
This is my run script
set build_components {
core init
drivers/timer
server/ffat_fs
test/libc_ffat_usb
}
source ${genode_dir}/repos/base/run/platform_drv.inc
append_platform_drv_build_components
build $build_components
create_boot_directory
#
# Generate config
#
set config {
}
append_platform_drv_config
append config {
}
append_if [have_spec gpio] config {
}
append config {
}
install_config $config
set boot_modules {
core init timer
ld.lib.so
libc.lib.so
ffat_fs
test-libc_ffat_usb
test2.txt
}
lappend_if [have_spec usb] boot_modules usb_drv
lappend_if [have_spec gpio] boot_modules gpio_drv
append_platform_drv_boot_modules
build_boot_image $boot_modules

Re: Running demo on Virtualbox
It was a silly thing after all: I was expecting run/demo to run X
itself or run on framebuffer somehow, so I didn't actually have X
started.
Starting X and doing `DISPLAY=:0 make run/demo` did it.
I'll move on to actually writing code now.
Thanks!

Qemu requires SDL for the display. Please add:
QEMU_OPT += -sdl
to your build.conf file that should fix the issue.
