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 Forum,

I am trying to collect and run the NetX_dhcpv4_client project from the r20an0585eu0127– ek- ra6m4 example projects.zip group of demo projects. I’ve what I suppose is a standard install of the FSP4.3.0 decline and toolchain. If I import the below project from the zip file it looks like it imports clean but will not compile. I’m getting the error saying the toolchain configured for the project isn’t presently available. Where have I gone wrong with this project importation? I would have allowed all these example projects to be set up to run on the default toolchain.

Thank you for the help!!

    Hello vikas,

    Open the project properties, C/C Build-> Settings-> Toolchain tab

    Unselect the Use integrated toolchain account checkbox, click Apply, elect the Use integrated toolchain account back, this will modify the current toolchain to the toolchain available on your system. Click Apply and Close, done!

Hello Forum,

It’s been 5 years since I’ve done important firmware and have forgotten a lot of how this device works. I am trying to learn a simple netx application running. In the older Community ssp, there use to be a tab like properties or something that would allow me to change things like the thread name and set the heap and stack sizes. Where is that now hidden? I allowed it use to be down in the lower section there next to the problems tab.

Thank you for the help!

Hi,

I need to apply the virtual EEPROM on a RA2E1. In principle, this mechanism works, and I can write and read the record IDs. During the production of the board, I need to program the original content of this rec id. Is there any documentation or example on how to make the memory address’s binary file starting from 0x40100000?

Thanks, Nidhi

    Hi Nidhi,

    Thanks for reaching out to Volt.Tech Engineering Community.

    If I understand right you need to program the data flash of the device just right?
    The data flash can be written in both ways, by Renesas Flash Programmer, or by self-programming (by the software running on the device).

    To program only the data flash with Renesas Flash Programmer, the file used to program the device would require to hold only data for the data flash address range. A. srec,. hex, or. bin file can be used with RFP to give the data to be programmed into the flash.

    Regards

Hello, I am planning to use RA2A1 MCU for a design with 24-bit ADC sampling and relay control.

Because there are many 5V peripherals in this system, it’ll be much simple if the RA2A1 runs at a 5 Volt power supply.

Most of the RA2A1 examples are running at a 3.3 V power supply, what’s the potential problem if run at a 5 V power supply?

Regards

    Hello, None RA2 family can run from 1.6 V to 5V. The data sheet & hardware user manual that can be found on the Renesas web give further detail. Thank You

Hi, I would like to trigger ADC conversion with GPT capture and compares events without using the FSP configuration. I couldn’t figure out how to do it, is there any example project about it? Thank you

    Hello, It’s easy. see the section, 3 of the manual (RA4M1) To trigger the A/D, write to register ELSR8 (R_ELC. ELSR (8), and the number you write to that register is the event number shown in table 18.3, nearly between 0x57 and 0x96, depending on which timer, which event (and maybe which processor).Read more

    Hello,

    It’s easy. see the section, 3 of the manual (RA4M1)

    To trigger the A/D, write to register ELSR8 (R_ELC. ELSR (8), and the number you write to that register is the event number shown in table 18.3, nearly between 0x57 and 0x96, depending on which timer, which event (and maybe which processor).

    First, you have to enable the ELC registers by writing 1 to R_ELC. ELCR and writing to the module stop register.

    You also have to inform the A/D by writing 9 to ADSTRGR (see section 35.2.12)

    Thank You
