F28035 CAN Bootloader

Other Parts Discussed in Thread: TMS320F28035

Hi,

I'd like to implement a custom CAN bootloader into a TMS320F28035 micro. Is that possible? After some initial reading of the datasheets it appears that there is a ROM bootloader already programmed in the device, but there doesn't seem to be a way to implement my own bootloader into flash. Is that correct? If so, is there a tool available (that runs on a Windows PC) that I can load a hex file (or s-record) into and reprogram the flash (via CAN) with my application?

Thanks,

Mike

    Mike,

    It is not possible to change the boot loader that is within the ROM, but you can write your own and put it into the OTP or into the flash.  Take a look at this application note: "Custom Bootloader Options via OTP" www.ti.com/lit/spraaq3
