Thanks, this seems to be the closest to our needs.

Eventually I could use JTAG, but it would be much more convenient for
the user if CAN could be used on new chips.
There will be a code to start from plus TI provides flashing API too,
but since I have no experience with TMS320, I was hoping that someone
has commercially available loader (binary) I could send over to blank
TMS320 and flash it through that.

We have a TMS320F240 CAN flash for application, node ID setup, serial
numbers but this cannot boot new chips. In case of power fail while
application flash, the unit is a repair what requires service using a jtag
emulator. The F240 was a early family device and the time we wrote the SW,
TI changed flash specification several times regarding the block write and
erase capabilities.

The ROM bootloader allows only loading chunk of code into RAM and
execute it and I am wondering if there is any second stage loader out
there. Looked through TI appnotes, but could not find anything for this CPU.
Thanks
