Hi,

I’m using RF7A6M2AF MCU. I’m working at the register level and don’t use Renesas libraries. I’m trying to set up the MCU so I could spark ADC sampling from GPT.

I do have a GPT formerly working in the circle. I did set ADTRAUEN to 1 in the GTINTAD register and GTADTRA to 2, so the ADC trigger event starts early on during the GPT up-count. To confirm that the ELC_EVENT_GPT1_AD_TRIG_A event actually happens I’ve configured an interrupt for it and it does get triggered.

The thing I must be missing is the configuration at the ADC level for the trigger. A single checkup from the software trigger is working rightly and I can see ELC_EVENT_ADC1_SCAN_END related interrupt being triggered but if I configure ADCSR register TRGE and EXTRG fields to enable synchronous trigger I can not get ADC to work. I was looking into the ADSTRGR register to set a trigger for the ADC, but I don’t see an option for the GPT.

What am I missing?

Kind regards.

    Hello, Thanks for reaching out to Volt Tech Engineering Community. Do you have set the ELSRn to register? For example, ELSR8 register (for ADC unit 0)? You require to set this register with the right value from Table 19.3 according to your preferred GPT channel and event. Thank & Regards

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 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 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 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.

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?

    Hi Alex,

    The exchange mode for MCU boot uses the scratch area as an intermediate area in order to complete the exchange of the 2 images. The process of switching is done like below. However, then no information is lost, If a power failure occurs.

    The scratch area must be large enough to store the largest sector that’s going to be shifted. For RA2 MCUs, the scratch area should be set up to 0x800 when exchange mode is used.

    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)

Hello,

We are changing a product from a Community to an RA processor. Can we use the same E2 Studio and switch between SSP and FSP? We’ll have times when we are doing maintenance on the Community product and also doing dev on the new RA board.

Is there a specific version of E2 that can do this?

Does it make sense, or should we’ve two different E2 setups?
