i found that the command "/tftboot/u-boot.srec > /dev/ttyS0" also
doesn't work for me, my solution was to get minicom.
Once that was up & working i transfered the u-boot.srec file using
ASCII transfer mode - this works nicely.

Hello, if anyone have seen this kind of problem......
I compiled successfully my images, the problem is when I want to boot
on my Spartan3E Starter board.
-The problem is on the reference Xilinx Spartan3E_10.1_lite. But I
really don't know what happen, 'cos everything seems to be alright.
-I have last EDK SP3 installed, on ubuntu 9. My EDK works very good, (I
have tested on my own embedded project...)
-I open my Xilinx Spartan3E_10.1_lite reference system.xmp, then EDK
asks me to upgrade the project, then I choose NO.
-I make netlist, libraries, bitstring, the .elf and lik, I build my
"fsboot" software project with "MARK INIT_BRAM", the rest software
projects have not selected "MARK BRAM". I download bitstring to the
Board...
-I have tested my serial cable, I have tested my CPU serial port with
a router, so it works good.
-I have tested with windows hyperterminal and linux minicom,
configuring it on " 8 bit data, parity even, no hardware or software
error detection, 1 stop bit, and 115200 bit speed.
-Because this is my first job on petalinux, maybe I have 'nt take care
about some kind of stuff, that is why I'm describing all this.
-Reviewing some Petaliniux tutorial and docs, everybody tells when I
download the bitstring by my jtag usb cable into the Board, some
"fsboot ...." words appears on the serial console, then I have to put
"s" to call U-boot, and cat /tftboot/u-boot.srec > /dev/ttyS0 (this
is my serial port).
-Well, when I download the jtag bit string, no word appears on my
serial console. I do'nt know if I have to put some command on the
console, or just wait for a text. I want to say, that I know it is my
first job, so my project is basic, taken from the given reference, not
modification at all...
-I put command cat /tftboot/u-boot.srec > /dev/ttyS0, I noticed that
is takes a while, regarding that I put /tftboot/u-boot.srec >
/dev/ttyS1 too (I do not use ttyS1), and it goes quikly, so it would
say that something is happening on my serial ttyS0. But no word appears
on my hyperterminal or on my minicom...
-When I download the bitstring, I do know it is programed with
soemthing, because I have the board always with some LED on, to test if
the board have programmed with the bitstring, the LED turn off..
-I really dont know, my images are wating for being dowloading, the
problem is with my fsboot. (I do know the sources and headers are OK
for fsboot software project)
-Note that I use the UART serial DTE port on my board for my own VHDL
application, so it works good too....
-Please, maybe you have some skill that you tell me, why I have not the
fsboot words asking me to boot, if I choose the basic reference....
-Help me please if you have on idea. of what it is happening to me.
Thaks and sorry for being so long, just I wanted to be clear, to save
time...
Regards orlando.
