I want to read the file test.jpg. This are 8bit hex-values. My first
try is to put it out on standard output.
Just the output is uncommanded. The error must com from read part.
red>ghdl -a -Wa,--32 tb_lesen2.vhd
red> ghdl -e -Wa,--32 -Wl,-m32 tb_read
red> ghdl -r tb_read --stop-time=3000ns
./tb_read:internal error: file: IO error
ghdl: compilation error
