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
