S32K148 defaultISR with SDK RTM3.0.0

[wdong]

hello, I am confused,

when I use the SDK RTM3.0.0, the board will defaultISR when getting the PIN_DRVS_Init(),as followed; but there is no problem without SDK，

all the programs are attached, please help me, Thank you!

Hello @wdong ,

Unfortunately I don't have board to check the code but as per my knowledge there are two issues.

1. In processor you added more processors there you need to add only one processor depending on your no of pins. Consider if you are using 144 pin configuration then keep only one cpu:S32K148_144 and remove other components. 

After remove you can see like 

After removing if you are facing error then you can remove

1. RAM from Generator Configuration 

2. Cpu:S32K148_144 from processor

after removing you can add new Generator configuration and Processor by following below steps

1. Go to Component library 

2. Select processor 

3. Go to S32Kx-> S32K248 and double click you will see like below 

Select proper pin configuration and click finish.

Now Initialize clock and pins like below.

That's done .

many thanks. I change the program as your solution, but it doesn't work still.

Hi wdong,

Test attached two projects on S32K148EVB RevB, did not get hard fault.
Would you please let me know which board are you testing?
If there are some difference between S32K148EVB with your custom board?
Notice if external crystal is used and whether it's frequency meet the configuration.

Best Regards,
Robin

hi,

The board is designed by myself, the basic system is attached, thank you

I also found that, if i use the following code before pin init, it will work.

PCC-> PCCn[PCC_PORTA_INDEX] = PCC_PCCn_CGC_MASK; /* Enable clock to PORT A */

So, maybe some problem with my clock init.

I can see you configure PTA0 as output. If you click Generate Processor Expert Code, then you should see the clkGate=true in clockMan1.c.
The clock gate of PORT A should be initialize by Processor Expert, do not need enabled by yourself.

Best Regards,
Robin

but mine is 0x0, oh no!

[Robin_Shen · Accepted solution]

Have you check the clockMan1.c, did Processor Expert set clkGate=true for PORTA?
If still not work, then please update SDK S32K1xx RTM 3.0.3 by refer: S32 Design Studio for ARM 2.2 - Update 1 available

hello，I have solved the problem, it's hardware problem, thank you very much!

[wdong]

I already update the SDK. and I checked that, clkGate = true in clockMan1.c, but the registers value is still 0x0, I am confused.

Please help me.
