Hi, I
try the semihosting for cortex-m profile and it's working
pretty well. Now I wwant to use the fileIO semihosting the be
able to host all the files on my host and access it by my
running application. So far, I can open a file with fopen, and
write/red into it. The
question is about the drive emulation. On my real board I have
a SPI flash, and I use a fat system (Chan fatFS drive 0: )).
On my board I also have an SD card (used by Chan fatFS (drive
1: )). I try to figure how I could emulate those drive to have
my files hosted on my host. I would like to have each drive in
separate folder like: c:\drive0, c:\drive1. When
I open a file in my application 0:myFile.txt I would like to
have it on my host in c:\drive0\myFile.txt. Same thing for
drive 1: Is
it something doable ? Can I configure QEMU to have such
arrangement ? If possible I don't want to modify my
application for drive access. Regards Jonathan |
