Loading U-boot through UART to bf609 ( Response not complete )

Hi all,


I had a problem when trying to download the u-boot.ldr through UART to EZ-kit BF609. The problem is when I execute the bfin-uclinux-ldr command,

I got this:

y@debian:/tftpboot$ bfin-uclinux-ldr -l /tftpboot/u-boot.ldr /dev/ttyUSB1 && kermit -l /dev/ttyUSB1 -b 57600 -C connect

Loading LDR /tftpboot/u-boot.ldr ... OK!

Opening /dev/ttyUSB1 ... OK!

Configuring terminal I/O ... OK!

Trying to send autobaud ... OK!

Trying to read autobaud ... OK!

Checking autobaud ... OK!

Autobaud result: 115200bps 23.961mhz (header:0xBF DLL:0x0D DLH:0x00 fin:0x00)

Sending blocks of DXE 1 ... OK!

You may want to run minicom or kermit now

Quick tip: run 'ldr <ldr> <devspec> && minicom'

Connecting to /dev/ttyUSB1, 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.





Then I waited for some time, hoping to see some feedback through this terminal at least. But nothing.

So I opened another terminal then started minicom, after seeing the var/lock/LCK..USB1 error, I deleted the lock file and started minicom again. But still nothing, no interface there,


Any ideas? Thanks,
