How to debug dm6446?

Started by liqi...@gmail.com November 12, 2007
I'm a newcomer to DaVinci. There  is an ARM core and a TM320 DSP in a
single dm6446 chip, but there is only one jtag port. So how to debug
the chip?

Debug as usual, by toggling LEDs and printing out to the RS-232 port. Vladimir Vassilevsky DSP and Mixed Signal Design Consultant http://www.abvolt.com
