Anyone has TMS320F280x CAN FLASH loader ?

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

Check out the "microCANopen" link at http://www.esacademy.com/.  You
might be able to adapt this into a second stage loader you could use.
If you register you can view the source code for free, and if you need
to use it in a commercial product they have an inexpensive license.

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.

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.

TI 320F28xx is among others.

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