Im working on aproject where i use M16C/65 (R5F3651NDFC) controller. I want to be able to flash the .mot file with FDT Simple Interface using a UART connection on RXD/TXD1. Between the controller and the computer is the VNC2 USB-Device from FTDI. I tried several settings the last days. The only one that lastly works is with device R5F3651NB_7Line and a bausrate of 9600bps. And thas is very slow. it takes almost 30mins to flash the .mot file. When I use higher baudrates like 38400 or 57600 i get the following Error:
Clock Frequency (External) = N/A, Clock Mode = N/A, CKM = N/A, and CKP = N/AConnecting to device 'R5F3651NB_7Line' on 'COM9'Configuration:'BOOT Mode' connection - using emulated interfaceOpening port 'COM9' ...Loading Comms DLLLoaded Comms DLLInitiating BOOT SCI sequenceAttempting 9600Attempting 4800Changing baud rate to 57600 bpsError No 15005: 'COM9' read time out
I use the version : FDT V.4.09 Release 03
How can I Solve this?
Thanks in advance

Hi JB, No unfortunately not yet. Yes I checked the connection and it works fine. Like I said I can flash the device but only with 9600 bps what is very slow(takes almost 1h to flasch the mcu). The RS232 Transceiver I use is on the Target Board (VNC2 IC). The Problem is I cant set higher baudrate than 9600 bps.

Did you have a look at M16C/65 sample codes? www.renesas.com/.../m16c65.html This one explains about user boot to program a file downloaded from PC using XMODEM. www.renesas.com/.../D3007544.html
