Hello,

I have added a new Device for flashing it, please see the following
lines ... I have tested it on WindowsXP it runs well so far ;-),
with MINGW openocd will NOT build silently ( missing symbols at the
final link), after running make You have to do additionally:

cd src
gcc -std=gnu99 -g -O2 -D__USE_MINGW_ANSI_STDIO -Wall -Wstrict-prototypes
-Wformat-security -Wextra -Wno-unused-parameter -Wbad-function-cast
-Wcast-align -Wredundant-decls -Werror -o openocd.exe main.o
./flash/nor/.libs/libocdflashnor.a ./.libs/libopenocd.a -lws2_32
-lftd2xx ./flash/nor/.libs/libocdflashnor.a ./helper/.libs/libhelper.a
cd ..
make install

Best regards, Enrico
