Antonio,
As Dirk points out there is an application called DVFlasher that may be
used to perform this task over the serial port, however the version
used by the Davinci board will not work on the DM355 due some
differences on the magic signature used for the UBL.
If there is a BootRom/RBL similiar to DM644x in DM355, there is no
compatible "DVFlasher" tool from TI available for this??
If magic signature of DM355 is different to DM644x I understand that
our DM644x open source UBL tools
http://wiki.davincidsp.com/index.php?title=RBL_UBL_and_host_program
will not work. But I would strongly assume that TI has a compatible
"DVFlasher" tool (?).
Btw.: Any pointers to this "different magic signature"? Would it be a
big task to add it to our open source RBL/UBL tooling?
There is another option if you already have a standard ARM JTAG (if no,
you can get a cheap Olimex OpenOCD based by less than $100 if I recall
correctly).
Do you talk about
http://openhardware.net/Embedded_ARM/OpenOCD_JTAG/
for DM355?
Any hints how to use this? Would be nice if we add it to wiki ;)
Dirk
you can use the "setup" program of the bootloader provided
by the RidgeRun free SDK for DM355. This is a small firmware you can
load on IRAM to perform the low level init, and after that you can load
u-boot image and burn it to flash (I have done that several times). If
you are interested on this idea I can provide you more information.

Hello,
I am starting working with dm355 EVM, and one question arises: Is
there's any other way to load uBoot without Code Composer Studio?? Is
there any open-source aplication do perform this?
It seems a waste having to buy CCS only to load the flash with uBoot.
Best Regards,
