Hi:
I have recently begun using an EzDSP board from Spectrum Digital for the TMS320F2812. On the board is a FPGA implementing an embedded JTAG emulation port, which talks to the PC via a parallel printer port.
I am thinking it is possible to use this board as a JTAG emulator for a TMS320F2812 chip on *any* board, such as one I design myself. That way, I could have general purpose JTAG emulation (though perhaps restricted to the F2812) for the price of an EzDSP board, instead of the minimum of $1299 that other emulators cost.
What other limitations might this introduce? There appear to be flash programming capabilities in the other emulators, but as I understand the F2812, it needs to program itself via a RAM based routine anyway, and this can be done (albeit in a slightly awkward manner) through CCS using a plugin that TI now makes available on the web for free.
Any comments would be appreciated.
Good day!
