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?
