[microblaze-uclinux] Fwd: SREC File Upload Issues

[Matt Staniszewski <matt.staniszewski@xxxxxxxxx>]

Hi,

I'm having problems uploading my u-boot.srec file.  I've followed
instructions as outlined on Petlogix's website for setting up uClinux
for my Xilinx Spartan 3E Starter Kit.  Also, I used their example for
my .kermrc file for Kermit:

set line /dev/ttyS0
set speed 115200

set carrier-watch off
set handshake none

set flow-control none
robust

set file type bin
set file name lit

set rec pack 1000
set send pack 1000

set key \127 \8
set key \8 \127

set window 5

However, if I download my .bit file to my S3E, press 's' to load my
SREC image, then issue the following command:


cat /tftpboot/u-boot.srec > /dev/ttyS0

Kermit immediately reports "Invalid SREC Image!"  This happens as both
root and a normal user.

However, I tried using Cutecom instead to upload the SREC file, and
then the twirler started and the image got uploaded.  I feel like
there's something wrong with my Kermit settings that is sending extra
control characters.  Also, even though Cutecom uploaded the file,
Kermit shows that my board gets hung up at:


Found romfs @ 0x2414a000 (0x00235000)
#### klimit 2415b000 ####

Moving 0x00235000 bytes from 0x2414a000 to 0x2415a5c0
New klimit: 0x24390000


Thanks for any suggestions.

Matt
