  • Please see chapter 25.4 for flash programming in serial mode, table 25.21 for pin connections.


    Chrystal is connected to E1-F2.
    Vss is on F3 and E8.
    CNVss on D2 must be pulled up.

    I hope I marked all relevant pins.

    I don't see what you mean on the pinterest page but it is probably OK.

  •  i mad e wrong alignment about chip pins.now i corrected and it seems my xtal location is ok.

    i dedected pins.

    i will put mcu back and report u .

    But u didnt answer my question about renesas programming software.

    when i load my file it shows all FF :(

  • Sorry, I cannot answer the question about the programming software as I (a) am not sure which software you use and (b) don't know your memory dump.
    I assume you mean FDT software. The message window should say which memory areas have been read like this:
    FCF Settings Applied: R5F64535, (C:\Tool\Renesas\FDT4.09\kernels\ProtD\R5F64535\Renesas\1_0_00\)
    This kernel will set the E2 Data Flash as ECC OFF
    Opening file Z:\_SharedDirectory\WorkSpace\FDT\1MB_FFF00000.mot
    File loaded: 0xFFF00000 -> 0xFFFFFFFF [User Flash]
    File loaded: 0x00060000 -> 0x00061FFF [Data Flash]
    File loaded: 0x00062000 -> 0x00063FFF [E2 Data Flash]
    ID Code = 0xC3 0x46 0x0F 0x85 0x70 0xF4 0x4E
  • Can u please mark to me rx and tx pins from picture :(

    Because im very confused about pinout :(

    Thank you already

  • I'm sorry, where is the problem?
    RxD is P6_6 and TxD is P6_7 which are not too difficult to find in the pin map I sent earlier.
  • i connected them and no connection. reset pin low , all vcc and vss pins are conected . im using software which u send me .
    are there any development board i can buy, maybe i will change mcu and programme there. or any other solutions do u have for me?
    also for new mcu i couldnt find seller
  • There has been a starter kit for R32C/111, but nothing for a chip in LGA package.
    www.renesas.com/.../renesas-starter-kit-for-r32c-111.html
    Important pins for mode selection are ports P5_0 and P5_5, P6_5 and CNVss. RESET has to be released to "H" once the mode selection pins are set to flash programming mode.
    I have no idea where to buy devices in LGA. As it is difficult to solder there will never have been many distributors selling it.
  • i just sawthis message , thisforum has very different style :)
  • İ did all, only i put reset always high , what i have to do with reset exactly i dont und.im using ft232rl based usb converter , there are dtr and rts pins , are any of them is reset? , also on datasheet They put a button to cnvss too.can u please explain this button on cnvss ?what's pull up resistor value for this mcu? And what i have to do with reset? Also any method to und which mode in mcu from bussy pin with led or sth?

    I know I asked so many questions

    Thanx already
