[Carlo Agostini <carlo dot agostini at yacme dot com>]

Hi folk
I'm a student of engineering of Bologna (Italy) and I am working  with
systems linux embedded
In order to begin I am compiling redboot for a system i386

I have get the current version of eCos packages via CVS version 1.3
I type the following in RedHat 7.1

ecosconfig new pc redboot
ecosconfig import ../i386/pc/...../redboot_FLOPPY.ecm
make

I 've successfully compiled both redboot.bin & redboot.elf

Redboot runs from a floppy disk on 486 pc

I wanted to try to load through the serial port  a program
hello world in the RAM with the PC on which it turns redboot.

I 've a problem whith load :

load -m xmodem -b 0x00080700

following is the message
CCCCCCCCCççççççççCan't load 'A ' :Timed Out

I send fileexe(hello) whith command

sz --xmodem hello < /dev/ttyS0 > /dev/ttyS0


How I can resolve this my problem?

Thanks in advance and regards

Carlo
