What are your results? Any error messages/different behavior than
described in my emails?

I just tried to reproduce what you did, everything worked as expected :-)

My hardware is the AM1808 experimenter's kit from LogicPD, base board
1015525 Rev. 2, the SOM is 1015232 Rev. 4. It is connected to a USB
serial port on my Linux box, /dev/ttyUSB0.

$ cd u-boot
$ git checkout 4fff329
$ export CROSS_COMPILE=arm-none-linux-gnueabi-
$ make mrproper; make da850evm_config; make -j9 all

$ cd ..
$ mkdir ben
$ ln -s ../u-boot/u-boot.bin .
$ nano OMAP-L138.ini   (copy&pasted the configuration from your email
to the text editor)

I am using flash and boot utils 2.31 as well. Mono version is 2.4, I
had to rebuild the utilities to make them run with mono on my machine.
I modified the flash and boot utils' makefiles to build for the AM1808
target only (otherwise I would have to install the DSP compiler).

$ mono ../flash-2.31/HexAIS_OMAP-L138.exe

$ mono ../flash-2.31/sfh_OMAP-L138.exe -erase -targetType AM1808 -p /dev/ttyUSB0
(added the -targetType option, default is OMAP-L138)

$ mono ../flash-2.31/sfh_OMAP-L138.exe -targetType AM1808 -p
/dev/ttyUSB0 -flash_noubl ais_output.bin
(added -targetType and -p options)

$ minicom
-> reboot of the board with boot configuration set to "boot from SPI"
-> u-boot prompt appears on the serial console:

If I try the same with git checkout ab86f72c354f9b2572, I get no
response on the serial console. Furthermore I also tried the most
recent u-boot, 6f4dd40cddbd69c56fec1285fee02cbd5a3833d8, Prepare
v2011.06-rc2, no response on the serial port console.

Thank you very much for your help! Hope the information above helps,
do you need anything else?
