Hello anyone,
I compiled eCos and RedBoot for i386.
I booted my i386 from a diskette with RedBoot and it boots correctly.
If I connect the i386 via GDB, i can load my sample applications and run
them correctly.
The problem is that it fails sending the application via minicom. What I
type is:
Redboot> load -r -v -m xmodem -b 0x200000 helloWorld
In minicom: Ctrl-A-S then I choose xmodem protocol, helloWorld file. A
window appears, and inside it :
Sending helloWorld file, 52 blocks. Give your local XMODEM recieve
command now.
Xmodem sectors/kbytes sent: 0 / 0 kb
After a while:
Retry 0 : Timeout on sector ACK
And in the redboot shell :
CCCCCC#######Can't load '<null>': Timed out.
Another problem:
If I put the same 'helloWorld' file on, let's say : /dev/hda1, root
directory
which is the correct syntax for the load command to load it ?
Thanks very much for any help.
Marco
