I am glad that I finally found this forum.
I am working a MCU which is 70F3477A. I decided to buy E1 since I can use it to program MCU flash and more.
I use Flash Programmer V2.05 since it support V850 family. The MCU I am working is soldered on the board which a header for flash programming and it uses CSI3 lines.
I follow information on Connection documents for E1/E20 and V850 family.
The problem I have now is I get error message "No response from Target Microcontroller (FLMD)". I provide MCU with +3.3V
MCU has its own RESET circuit. Since E1 has rising edge RESET signal, so I don't connect it to MCU.
I hope someone can give me some insights.
Thank you all
Thank you for responding.
The MCU is on a board but not my design and it is an HDMI board. The old MCU got shot (blown), so I have to replace it with a new one and I need to rewrite the F/W since self-programming won't work if MCU is not running.
The board can be self-powered either from the system or external. I am using external 3.3V aurrently.
I am following connection information as shown in 2 pictures below.
At this moment, all I get is an error message "No response from Target Microcontroller (FLMD)"
The diagram from 2nd picture is using CSIB3 on MCU.
The E1 needs to be able to control reset to put the device in programming mode. If there is a circuit on the board that makes that impossible, you'll want to program the device separately (for instance, on a development board) or temporarily disable the reset circuit on the board.
