Hello everyone. I’m trying to use a driver that uses spi with my RA6M3 board. But I ran into a problem that I had not encountered ahead. The NMI interrupt goes into an infinite loop and doesn’t live. I do not know much about NMI so I do not know what to do. The NMI pin on the RA6M3 board is P200. P200 isn’t enabled but never gets stuck in NMI masking function in the spi_transmit process. And it can not exit NMI_Handler.

Thank You

    Hello, What's the value of the NMISR register when the NMI handler is called? The value of the register gives some data about the cause of the NMI interrupt. Also at what point inside the 'spi_transmit' does the NMI occur? Regards Alex Thomas

    Hello,

    What’s the value of the NMISR register when the NMI handler is called?

    The value of the register gives some data about the cause of the NMI interrupt.

    Also at what point inside the ‘spi_transmit‘ does the NMI occur?

Hello. I have the RA6M3 development board. With this card, I want to save the HDMI image to an SD card or USB flash, and at the same time, I want to display it on the LCD screen. Two styles come to mind. Which makes further sense?

1) First method, I can convert it to HDMI to the serial camera interface, control it with PDC, print to LCD screen, and save it to flash. How do I convert from HDMI to serial camera interface if I do this?

2) second method I’ll convert from HDMI to USB, save it to flash, and show it on the LCD screen.

Which of the 2 methods I mentioned over would be more straightforward and more logical? Are these methods doable? What do you suppose will be the quality of the video I’ll record in the most applicable method? Can I record 1080P 60 FPS? I would be very thankful if you could help me with your experience. Thank you very much for your support.

Have a nice day.
Enjoy your work.

Hi everyone,
I am starting on the RA6M3 and testing to run the Guiliani demo on the M13- RA6M3- EK- SDRAM kit.

I learn stuck on a silly thing, I do not know how to program theresources.dat file directly in the QSPI of the kit.
I can not find the” Load Ancillary file” command.

Can someone help me?
Thanks a lot

    In e2-studio 2022-07 binary files can now be downloaded as part of the debug configuration in the startup tab. For example, the highlighted line will load the raw binary file into the QSPI memory every time the program to be debugged is downloaded.

Dear Volt.Tech, I’ve been trying to run the IIC master example code with the EK- RA6M3 board but it doesn’t make with the latest FSP version(4.0.0). To workaround this I installed v3.8.0 but I’m facing issues with the IDE where it doesn’t enter the function which has a multi-byte i2c read sequence. I’m using the MAX86161 detector to test this out. Thanks & Regards

    Hi, Thanks for reaching out to Engineering Community. Could you please check your e² studio version? Please note that FSP versions of 3.7.0 and later require a minimal e² studio version of 2022- 04 and FSP versions of 4.0.0 and later require a minimum e² studio version of 2022- 07. Best regards,

Hello,

I’m using the RA6M3 regulator in one of the applications where I need 2 UARTS. uart0 and uart1. In the configurator, I’ve configured uart0 for 115200 buad and uart1 for 9600 buad ( as that’s what I need to communicate to my peripherals). But ever these 2 different baud rates don’t work together. Seems I can configure both at 115200 or both at 9600 and also both would work( I tried checking it on teraterm).
Is there any way to configure 2 different devices uart0 and uart1 to different baud rates? Any suggestion in this direction would help me.

    Thanks for reaching out to Engineering Community. Could you try setting each baud rate with R_SCI_UART_BaudSet() function? Please make sure you call it after you have opened the SCI_UART channel and before you start any data transmission. Let us know if it helped. Regards,

    It seems to be caused by the read buffer (g_read_buf) only being 8 bytes in size, whereas the max packet size for the full speed bulk transfer is 64 bytes. The USB driver sets up a 64 byte transfer with the DMAC when R_USB_Read() is called, then the DMAC transfer over writes some other data in RAM.

I am currently working on a Renesas RA6M3 and was wondering if there is a possibility of working with a single (Full speed or High speed) USB port but switching between HCDC and HMSC based on the USB that is connected to the port. The only example (with FSP) that I have seen was the Multiport and the Composite but both of them work with PCDC instead of HCDC. Has anyone attempted this before? Swapping during runtime between the protocols seems not possible but I did like to ask here before moving on.

    the current USB driver does not support multiple classes in USB Host mode, this includes the USB_Basic stack.
