Hi
I want to use AES 256 encryption and decryption with the SCE7 crypto engine in one of my systems.

I’ve seen mbed tls support hardware acceleration. (through RA smart configurator)
Can anybody guide how to achieve AES with the RA6M2 SCE7 crypto engine?

Sample codes would help.

Thank You

    Hi Vikas, You can use the needed SCE driver by adding it to your design as below. Let us know if you have to follow- up questions. Alex

Hi,

I’m using Renesas RA6M2 MCU. I’m facing following problems related to internal RTC.
1. After RTC set at morning 9 am and device put in off state. At 6 pm when we going to check RTC it shows 1 hr delay.
2. Is it need to call RTC open api at every power ON?
3. I’m using FSP3.7. In that clock source not set in rtc open api. For break this issue, I set RTC clock source after rtc open api. But After callingR_RTC_ClockSourceSet( &g_rtc_ctrl) api, I observedR_RTC->RCR2_b. launch bit is 0. In this case RTC not running.

    2. In case of warm start or a hard reset (when VBATT powers RTC in case of power loss), is it need reinitialize RTC clock source?

    3. When VBATT powers RTC in case of power loss then what is the initialization sequence of RTC after warm start or a hard reset.

Hello, I am writing a charge haul for the RA6M2 processor. To do that, I need to do variations to startup.c, so I was wondering what the proper way of doing this is. Should I just modify the being startup.c in place? If I do so, is there any chance that it’ll be regenerated in its original form by the figure system?

Or the other volition I can suppose of is, count the startup.c from the figure( the right click menu has this) and produce a blank startup.c and colonize it with my code.
The reason for this is that I want to produce special vector functions that” forward” the intrude to either the charge haul itself or to the operation.

    Hi, The simplest way to guarantee that any changes you make to a FSP configurator generated line is to copy the line to the src folder and also count the original from the figure. Then also you can make the changes without the trouble of them being overwritten.

I am using FreeRTOS on the RA6M2, and what I need is a fairly accurate detention that works in the range of 1- 64 forevers. The software detention is way out in this range( 60us software detention turned out to be 84us), indeed when using critical task section and disabling irqs.I have tried rather using a tackle timekeeper like belowThis will not be veritably accurate but I was hoping the outflow would be small enough that I could ignore it. still, when I try this, the do while noway exits. ...Read more

I am using FreeRTOS on the RA6M2, and what I need is a fairly accurate detention that works in the range of 1- 64 forevers. The software detention is way out in this range( 60us software detention turned out to be 84us), indeed when using critical task section and disabling irqs.

I have tried rather using a tackle timekeeper like below

This will not be veritably accurate but I was hoping the outflow would be small enough that I could ignore it. still, when I try this, the do while noway exits. For some reason the timekeeper counter keeps resetting indeed though this is a one shot timekeeper. Can someone tell me where I am going wrong with this? I am using the configurator in the e2Studio IDE to set up the timekeeper.

Any results to this problem will be appreciated.

     You need to create the callback in the FSP configurator first, then inside your code create its implementation like this: volatile uint8_t timer_done; ....................... /* Example callback called when timer expires. */ void timer_callback (timer_callback_args_t * p_args) {   if (TIMER_EVENT_CRead more
