[U-Boot-Users] serial download of uImage

[himbA]

Hi
I'm a newbie to u-boot and pretty much to embedded systems.
I have a pxa255 board running 2.4.19 kernel with appropriate patches for 
ARM and xscale and u-boot 1.0.1 as bootloader already installed by 
somebody else (I just got the stuff).
Now, ethernet link is not working yet, due to some issues with SMSC 
LAN91c111 driver for linux, so I would like to use serial link to 
download new kernel image. I've built the kernel and I have uImage ready 
to go. I also have kermit setup according to DULG wiki. I can connect to 
serial port of my board just fine, issue 'loadb offset' and then hit 
ctrl-\c, issue 'send uImage'. this the  response i get:
*************************
SEND-class command failed.
 Packets sent: 2
 Retransmissions: 11
 Timeouts: 7
 Damaged packets: 5
 Fatal Kermit Protocol Error: Too many retries

Is there a cure for this?

Let me also mention thet I'm using USB-rs232 adapter on /dev/ttyUSB0
#l /dev/ttyUSB0
crw-rw----    1 root     uucp     188,   0 2004-02-09 00:14 /dev/ttyUSB0

I'm member of uucp.

Also is it possible to use SMSC LAN91c111 from u-boot to get 
dhcp+tftp+nfs boot working?


regards, himba

You should use the latest U-Boot version from CVS (1.0.2 or so), bacause 
around 1.0.1 there was an signed/unsigned problem inside U-Boot's LAN91c111 
driver --> result: ethernet doesn't work with full MAC range. In current CVS 
state this problem is fixed already.

What do you mean? Is the ethernet not workung under Linux or U-Boot ?

As Stefan Linz pointed out it may make sense to try a  newer  version
of U-Boot (top of CVS) whichincludes fixes for the ethernet driver.

First, did you configure kermit as described in
http://www.denx.de/twiki/bin/view/DULG/SystemSetup#Section_4.3.  ??

Second, try "send /bin uImage" to make sure to use _binary_ transfer mode.

Sure. Everything is possible :-) But I have no  idea  how  much  work
will be needed to get this working on your board.

Best regards,

I haven't lost my mind -- it's backed up on tape somewhere.

it was not working under linux, u-boot recognised it later due to some 
modifications in my host firewall. I kinda forgot to enable access to 
third sub-net since I addedd new NIC to use for communicating with 
devel. board :).
now it is downloading images right of the tftp server with no sweat.

i got a hint from a guy that setup running system, that serial interface 
is not configured to be used for serial download with u-boot, on that 
board :(
anyways, i'll have alook later, but since my eth interface is up and 
running i'm not in a hurry.
