Hi!I want to use the Renesas Flash Programmer with the RX113 Starter Kit to donwload my program.As far as I understand, I simply must put the MCU from Single Chip Mode to USB Boot Mode by setting SW4 to ON/ON, so that MD and UB (P14) are grounded, connect my PC to USB Port USB0_2, and then turn power on.
Bu when I do this, no device is detected by my PC. Using the Flash Progammer with an RX62 MCU works fine, it detecs a "Generic Boot USB Direct" device.
Do I need to connect to the USB Standard Type A connector instead of the Mini USB port? - But as I interprete the schematics, these share the same signals?
Thank you!
Hello Sbrauss,
What about powering mode? Did you set the jumpers in the right position so the board is powered from the bus?
Kind regards,
Sergey

Hi Sergey
Thanks for your answer! I had J7 at the wrong position, but it unfortunately still not works. I have appended a photo of the board. Is it correct to use USB Port USB0_2 as shown on the photo? I just plug in the USB connector and then a new USB device "Generic Boot USB Direct" (at least it is named that way with the RX62n) should be detected, right? Or do I need an additional USB driver different from the one of the the RX62n? - But this cannot be the case as also no unknown USB device is found...
Thanks & best regardsStephan
Hello Stephan,
At the first sight everything looks fine on the board. Do you see that the board is powered properly when you connect it via USB to the PC?
Hi SergeyYes, it is powered, LED POWER is on. You can see it on the photo I posted. I tried also with powering by the USB bus and by an external power supply (jumper J6 at 2-3 or off), but no change.The USB cable and the PC with Windows are fine, as I can connect a YRDKRX62N with the same cable to the same PC and it workes fine.
Thanks & best regards
Stephan
Sorry for the late reply.
It all looks correct, and it's hard to tell what's wrong there. And it's the shame there is no user's manual for this board available.
I would suggest you to try some USB sample application on your board to make sure the USB interface works correctly.
You can use CDC https://www.renesas.com/us/en/document/scd/rx-family-usb-peripheral-communication-device-class-driver-usb-mini-firmware-using-firmware or HID https://www.renesas.com/us/en/document/scd/rx-family-usb-peripheral-human-interface-devices-class-driver-usb-mini-firmware-using-firmware device examples.
Hello SergeyYes, maybe my board is defective... It is new, we bought it two weeks ago.Have you maybe access to a RX113 Starter Kit so that you could verify that it works?Thank you for your help & best regardsSteohan
I had a quick look at the archive. There is no prebuild project available, right? I currently also have no E1 debugger, as it was removed from the kit, so I cannot download it.
Unfortunately, I don't have this board to check if it works correctly. But I've finally found the User's Manual of it https://www.renesas.com/us/en/document/mat/renesas-starter-kit-rx113-users-manual which you may find useful.
I have some RA board though, and in that board I selected the self-powered mode, and connected the power via the second USB port, which made the trick. Maybe this will work for you as well.
Hi SergeyMany thanks for the manual, I so far had only a bad version downloaded from a third party web site.I tried it again with an external power supply, but it still not works.Maybe a resistor that must be mounted/removed?A bad board?Best regardsStephan
Do you maybe know someone else that has this board and can check?
I'll ask my colleagues if any of them have this or similar board.
