Hi everyone,
Does any one know if i can boot from Flash inside x28 series Delfino floating
point DSP. I need to save real estate for my design. I would like to use Delfino
for my design if i do not have to use External Flash for booting.
Thanks
Sankar

Sankar,
I haven't used the part, but I am 99.9999999% sure that the device can
run standalone. Check the datasheet - I believe that the correct 'pin
configuration' will allow it to boot from internal Flash [technically iy
does not 'boot', but executes the code directly from Flash]. I would
expect that to be the 'default mode of operation'.

Sankar,
I'm not sure about the Delfino series.
All the TMS320c28xx series of DSPs have a boot rom.
The boot rom has a special location in FLASH that it will jump to when the
appropriate boot mode is used.
Therefore, using the appropriate boot mode and placing a instruction to jump to
the code start address at the 'special' FLASH location results in booting in FLASH.
However, some of the DSPs have a different feature, especially the 6000 series,
where if the appropriate boot mode is used, then the first 1024 bytes of flash
are copied to RAM and executed.
Either of the two above methods make it easy to create a system that boots into
FLASH.
