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?

Thanks

    Hi Alex,

    The FSP and SSP releases are at a different meter and each version released is tested/ qualified against a specific version of e2-studio. The distribution download of the platform installer will ensure that the proper version of e2-studio will be with the FSP/ SSP version. I advise that you command a different and specific installation for SSP and FSP.

Hello,
I’m presently working on a RA2L1 custom board and using the E2 emulator lite for debugging by e2 studio. I want to flash the device. still, I’m not finding any clear methodology documented for the same. It would be helpful if the following points are clarified.

1. Do I’ve to use the Renesas flash programmer for flashing or it can be done through e2 studio?

2. Do I need to alter include anything in the code (tested fine in debug mode) specifically for flashing purpose?

3. Does the code need to be copied from flash to RAM in runtime for better performance? If yes, how do I insure that?
A step-wise guide application note on this topic would be of great help.

    Hello,

    Thanks for sharing your question with Volt Engineering Community!
    Please take a look at Code written for downloading and debugging with E2 will most likely just hang when run without a debugger attached.

    1. RFP is an option, or any development environment such as e2 studio or 3rd party tools can program the flash of the device.
    2. No special accommodations in the application code are necessary to enable flashing the device. Most designs will incorporate a custom charge-loader that uses a particular interface (UART, CAN, etc.) with a proprietary comm protocol, but this isn’t needed if the serial programming mode of the device can be set and a tool used that supports factory programming protocol.
    3. Renesas devices are optimized to execute code from the flash. Some designs that use comparatively slow flash technology can profit from RAM execution but that isn’t the case for RA devices.

Hii, It’s getting as far as setting NEWDATA in MCTL_RX (also sets MGSLOST, presumably when the coming message arrives). It also sets NDST in STR.

An acknowledged pulse is transmitted on CTX. So, I presume the filters are set correctly.

STR isn’t in HALT or RESET. The relevant bit is set in MIER.

is set to 0x4D, but bit 16 (IR) remains clear. The interrupt handler routine is never invoked. ISER0 bit 0 is set.

Other interrupts are working (RTC). Is there some other global interrupt enabled within the CAN module that I’ve overlooked?

    Hello Ashish,

    Thanks for sharing your question with Volt.Tech Engineering Community!
    Yes, you can program multiple devices with Renesas Flash Programmer. For Renesas Flash Programmer’s latest performances from V3.05.00 or later you can create a single design and specify the serial number of each emulator( E1 emulator/ E2/ E2 Lite) in the tool option when starting RFP via command.

    You can find all the necessary tools, manuals, and documents.
    https//www.renesas.com/us/en/software-tool/renesas-flash-programmer-programming-gui#overview

    As far as it concerns the MD pin then’s the suggested connection from the RA4M2 hardware manual for JTAG, SWD, and Serial Programming


    Generally, this pin should be high in debug mode and low when programming the device( flashing).
    Then there’s a different manual for e2 programmers.

    Hi, The FSP documentation includes examples of using AES encryption and decryption. For a PC- based tool, I would suggest putting something together using Python.

Hi,

I am using Ra6m1 MCU
I’ve 2 partitions

1. Bootloader partition from 0x00000000 to 0x00010000 flash memory
2. Application partition from 0x00010000 to 0x00080000

The problem I want to use IWDT at the Application partition, I’ve started iwdt at OFS0, but it doesn’t work.

Still, if I change the flash address of the Application partition to 0x00000000, IWDT works typically.

I suppose the problem relates to an option- setting memory position on flash. When I set the start address at 0x00010000( which is different from the initial address 0x00000000) = > the option- setting memory address will start from 0x00010400( according to” Renesas RA6M1 Group User’s Manual Hardware”), but the system may only read 0x00000400 so it keeps iwdt disable.

So how can I solve this problem?

Thank You

    Thanks for posting your question!

    You could check your IRQ- pin’s level when entering your interrupt message function in order to check if a rising or falling edge is detected. In case your pin’s level was initially low and when entering your message function it became high then a rising edge was detected. If your pin was initially high and also became low then a falling edge was detected. You could read your pin level by accessing the register shown in the picture below.

    For example, if your IRQ pin is P110, you could check its level in the interrupt message function like this:
    R_PORT1->PIDR_b. PIDR10 and check if it’s 1 (HIGH) or 0 (LOW).

    Another way is by using the already given API
    1.fsp_err_tR_IOPORT_PinRead(ioport_ctrl_t * constp_ctrl,bsp_io_port_pin_t pin,bsp_io_level_t *p_pin_value);

    Hi,

    The MISO pulses manifest at some stage in SPI idle state (while the clock is idle among the transfers).

    In master mode (in SPI, now no longer SCI_SPI) there’s the choice to pick out MOSI idle level at low or high based on the MOIFE and MOIFV bit settings in SPPCR.

    However, there’s no such choice in slave mode to choose the idle level of MISO.

    We could help greater in case you share more information about why those pulses are trouble to your application.
