Production Flash Loading of TMS570

Other Parts Discussed in Thread: UNIFLASH

Hello,

We are looking to use a TMS570 in a new product. I am looking for what is the best way to load in a CAN bootloader on the production line. It seems that the only way to do this is through JTAG with an XDS100 (or similar) and UniFlash. Is there an option that uses a simple serial interface such as ISP?

Thanks,

Matt

    Matt,

    Unfortunately not. You need to program through the JTAG port initially - at least to get the bootloader into the flash. Once you've got this done, you can then use the bootloader to re-program the flash through whatever interface it supports (QJ Wang has posted bootloaders for various peripherals, I think including CAN).

    You don't need to restrict yourself to the XDS100 though if speed is the concern -- there are faster emulators available. The highest end is the XDS560v2 class, but even the XDS200 should be something like 2-3 times faster than the XDS100v2.
