That is the flash protocol used by the ROM monitor. It's not usable for debugging. The debug interface is a JTAG-like interface using other pins. That protocol documentation is not publicly available and is unlikely to be disclosed. The only option is reverse engineering. I had plans on giving it a try, but never got around to it. And since then we've stopped using the V850 for new projects due to cost, performance and lousy support from NEC. /Andreas ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
