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.

Regards,

    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.

    Kind Regards,
    Vikas Nagpal

Hi Sir,

I found” R11AN0496EU0130“, and” R11AN0449EU0120“, but didn’t find any documentation on AES engine operation about RA2L1.

PC TOOL” Security Key Management Tool” does not support RA2L1

I also watch fsp document, but it does not help me important with following app confirmation.

FSP DOCUMENT ： https//renesas.github.io/ fsp/ group,r_m,p_s_a,c_r_y_p_t_o. html

Application：

PC (AES 256- bit encryption)-> RA2L1 (AES 256- bit decryption)-> device

Please give me the RA2L1 PC tool or some AES document (RA2L1) for our exhibition, thanks.

    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. The Security Key Management Tool is used for installing/ wrapping keys and so isn't the device you need for the application you describe.Read more

Hello,

Is the ambient temperature in the user manual the same as the chip temperature? EPadc_ek_ra2l1_ep, only read ADC value, not chip temperature. I wonder how the chip temperature should be calculated.

Preparation for Using the Temperature Sensor.


I am sorry, but I still do not understand. How to calculate the chip temperature? The log only printed the ADC value.

    Hi Nidhi,

    Thanks for reaching out to Volt.Tech Engineering Community.
    The user manual seems to be inaccurate when applying the word” ambient”. Die (chip) temperature can be calculated, as it’s proportional to the measured voltage from the ADC in the example. I attach a design that converts the voltage output of the ADC to the die temperature.

    I hope it helps.

    Hi, You should add the Clock Generation Circuit stack in the Stacks tab of RA Smart Configurator and configure the pins as follows. Also, the pins are configured as XCIN and XCOUT. Let us know if you have further issues. Regards

The MCU is RA2L1.I encountered a issue when I applied QE for Capacitive Touch( V3.1.0) to make tuning.
At the end, it said

TSCAP voltage error. Please check and review the design of the Target Board.
Failed to tuning.

Does anyone know why?

The TSCAP pin is tied to a capcitor. Is it incorrect?

    On reflection, you are having an issue with tuning, The tuning process is part of QE and the tuning "code" is download TSCAP ( P1.12 on the RA2L1 MCU ) should be connected to ground via a 10nF capacitor. Have you enabled the TSCAP pin in the FSP pin configuration?
