MPC5746C Run FreeRtos Demo error, enter IVOR1_Handler interrupt, have you encountered this problem?

Hello,

Sorry but with the provided description I am not able to help you.

Can you share with me closer details?

Are you using NXP EVB or any custom board?

Check FCCU status registers, RGM (FES and DES) for possible faults.

Is our example SW working correctly?:

Thank you very much for your answer. I seem to have found the problem. Currently, there is no OSC32K external pin in the MCU of the MPC5746C 100MAPBGA, and MC_ME.DRUN_MC.SXOSCON is enabled in the Demo of the SDK, but it does not judge and wait for MC_ME.GS. The .B.S_MTRANS bit is set to 0, so the program jumps to the IVOR1_Handler interrupt when the PIT register is manipulated.
It seems that the officially provided Demo Code does not distinguish the 100MAPBGA of the MPC5746C from other Pin packages.

Hello,

I encountered the same problem as you, but I came up when I initialized the ADC. The program directly enters the IVOR1_Handler interrupt and cannot come out. I want to ask how you solved it.

Hello, are you using the Demo example?

Hello,

I developed on the basis of other people's code, and also used the operating system. I just configured an ADC and the program entered this interrupt.

Hello,

The ADC I configured is written according to the Demo

Hi, which model of MPC5746C is used? See if MC_ME.DRUN_MC.SXOSCON is enabled?

Hi,

I use the official PE configuration.

You look at the model of your MPC5746C, is it 100pin, does the external support 32kHZ crystal oscillator, if it does not support the external 32k crystal oscillator, please do not choose, in addition, which version of SDK do you use?

I am using a 176-pin chip, and I still interrupt when I remove the clock. The version I use is S32 Design Studio for Power Architecture Version 2.1

What is the SDK version?

Re: MPC5746C Run FreeRtos Demo error，enter IVOR1_Handler interrupt

2548903578 — Wed, 08 Apr 2020 01:00:54 GMT

Sorry, I got it wrong. This is the SDK version.
