Hello,

Unfortunately this is English forum. Could you place your question in English as google translate of your question is quite blurry.

Best regards,

In SW32R294_RADARAPPDEMO_1_1_0, what are the meanings of TDMIMO and DDMIMO respectively? Is there any relevant documentation

Re: s32R294

Hello,

The documentation is part of RSDK release.

Please have a look at RSDK user manual for description of TDMIMO and DDMIMO .

I want to use the cascade mode of S32R294 to connect two TEF8102s. The two TEF8102s operate completely independently, and SPT time-sharing processes ADC data , Equivalent to replace two S32R274 functions with S32R294;

But I see the relevant manual of S32R294 says that CSI2 in cascaded mode must be the front end of the master-slave relationship, and only supports TEF82XX; Is my usage feasible?

Hello,

TEF81xx is capable of cascading. But none of our application boards supports it for TEF81xx.

I am curious about the screenshot, it looks like from RSDK reference manual.

Are you going to write the application yourself or you are going to use RSDK SW? Because RSDK does not support it as it express.

You will need TEF82xx for sure usecase.

Best regards,

Peter

Yes, this is the RSDK reference manual(SWS32R294_RadarSDK_1.4.0_D2207);

I read the code SW32R294_RADARAPPDEMO_1_1_0, which does not seem to support my usage. I need to write some code to support it.

Since I haven't got the development board yet, I would like to confirm whether the scheme of S32R294 and two TEF81XX is feasible

What is the master-slave mode of TEF82XX? Can I use these two modules independently? In addition, is there any documentation related to TEF81xx cascade usage?

Thank you

Hello,

This is not supported in HW or the SW. Cascading is supported for Barracuda (TEF82XX) with the CAB.
On top of that you can only connect a single BEST3 TEF81xx to the RADB board.

What is the master-slave mode of TEF82XX?

master - slave is the cascading mode, where one TEF82XX configures the other.

In addition, is there any documentation related to TEF81xx cascade usage?

No, only reference manual.

Best regards,

Peter

Thank you for your answer.

What I mean is whether such usage is supported on the chip function. If possible, I will make my own hardware and software

Hello,

As I have said. Cascading is not supported in HW for TEF810x.

This is what I understand from RADAR team explanation.

So for cascading applications please use TEF82xx.

Best regards,

Peter

I'm sorry, maybe I didn't make myself clear;

My method of use should not be considered as cascade. I use two TEF810X to connect to two CSI2 interfaces of S32R294 respectively.

They have different configurations and independent operation, for example, one is one with one receiving, the other is three sending and four receiving. SPT processes two pieces of data in time

Hello,

Yes, this is possible.

The S32R294 supports connection of 2 front end AFEs.

Best regards,

Peter
