We are currently working on a project related to IP telephony.For that we
need to load uClinux Image file to BF537 STAMP board. We hope to benefit
from your guidance.
The main error we are encountering is that, U-boot prompt from BF537 STAMP
is not showing up on minicom/kermit or any other terminal program.
Here is the procedure we are following.
We are using BF537 STAMP board and OS Ubuntu 9.04 Jaunty Version.
We have installed USB to serial converter drivers in ubuntu and then tried
to load u-boot by typing
bfin-uclinux-ldr -l u-boot.ldr /dev/ttyUSB0
CLI output is
bfin-uclinux-ldr -l u-boot.ldr /dev/ttyUSB0
Loading LDR u-boot.ldr ... OK!
Opening /dev/ttyUSB0 ... OK!
Configuring terminal I/O ... OK!
Trying to send autobaud ... OK!
Trying to read autobaud ... OK!
Checking autobaud ... OK!
Autobaud result: 115200bps 49.766mhz (header:0xBF DLL:0x1B DLH:0x00
fin:0x00)
Sending blocks of DXE 1 ... [1/2] [2/2] OK!
Sending blocks of DXE 2 ... [1/5] [2/5] [3/5] [4/5] [5/5] OK!
You may want to run minicom or kermit now
We tried it with both minicom and kermit. With keystrokes, the screen showed
a few bytes return on minicom
and kermit showed this result on CLI
bfin>connect
Connecting to /dev/ttyUSB0, speed 57600
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
after exit it showed
back to ossie at desktop
>bfin
Now here if we type version or any uboot command here it should work, but on
our pc it is actually the kermit interface not u boot and version command
shows the Kermit-C version.
The initial settings for kermit and minicom are given below:
In minicom the following parameters were set
57600 baud
8 data bits
Parity none
1 stop bit
H/W flow control off
and then we set the modem and dailing options.
Then we powered up the STAMP board but still the u-boot CLI did not show
up,Only a few bytes showed up upon keystrokes after resetting the board.
Kermit settings are as under:
set line /dev/ttyS0
define sz !sz \%0 > /dev/ttyS0 < /dev/ttyS0
set speed 57600
set carrier-watch off
set prefixing all
set parity none
set stop-bits 1
set modem none
set file type bin
set file name lit
set flow-control none
set prompt "bfin> "
We have set the board to following settings i.e.
SW16: Set the boot mode switch to position 7
JP9: Removed the UART loop back jumper
SW4: Set UART switch to {OFF,ON,OFF,ON}
SW6: Set flash switch to {ON,ON,ON,ON}
We have also tried to load u-boot.ldr using ldrviewer in Windows XP and then
accesing it in kermit or minicom in Ubuntu and hyperterminal on Windows XP
but no u-boot prompt was seen in any terminal program.
Dear all, please guide us, where are we going wrong or suggest some other
authenticated procedure to get the u-boot prompt up and running
