Hi NXP Device support team,
I am using following EVK S32K144EVB.
https://www.nxp.com/document/guide/get-started-with-the-s32k144evb:NGS-S32K144EVB
I am using following S32DS version :--
S32 Design Studio for S32 Platform
Version: 3.4
Build id: 201217 (Update 1
I am new to S32DS. For this purpose I first tried to test already tested sample project.
I tested this "ftm_periodic_interrupt_s32k144" project on my EVAL board its working fine, on my board S32K144EVB.
Then i created new "S32DS Application Project". In this project I did following task :--
1> configured clock for RUN mode, core clock runing at 80 MHZ.
2> Made PORTD 15,16 pins as output.
3> Configured FTM-0 as simple up timer.
I am using GDB PEMicro Interface Debugging.
I am getting following error when i do debugging, and execution of code is stuck at following DefaultISR . Getting this error :--
Initializing.
Target has been RESET and is active.
BusFault: A precise (synchronous) data access error has occurred.
Possible BusFault location: 0x4004C03C.
HardFault: A fault has been escalated to a hard fault.
As per this error address 0x4004C03C, it seems to be memory map of PORTD, from excel sheet "S32K1xx_Memory_Map.xlsx" :--
Port D multiplexing control Port D 44 4 4004C000 4004CFFF
Following is my main() routine :--
int main(void)
{
/* Write your code here */
/* Write your local variable definition here */
ftm_state_t state;
/* Initialize clock module */
CLOCK_SYS_Init(g_clockManConfigsArr, CLOCK_MANAGER_CONFIG_CNT, g_clockManCallbacksArr, CLOCK_MANAGER_CALLBACK_CNT);
CLOCK_SYS_UpdateConfiguration(0U, CLOCK_MANAGER_POLICY_AGREEMENT);
/* Initialize pins */
PINS_DRV_Init(NUM_OF_CONFIGURED_PINS0, g_pin_mux_InitConfigArr0);
/* Initialize FTM */
FTM_DRV_Init(INST_FLEXTIMER_MC_1, &flexTimer_mc_1_InitConfig_0, &state);
/* Initialize counter */
FTM_DRV_InitCounter(INST_FLEXTIMER_MC_1, &flexTimer_mc_1_TimerConfig_0);
/* Start Counter */
FTM_DRV_CounterStart(INST_FLEXTIMER_MC_1);
/* Loop */
for (;;)
{
/* Do no thing, just wait for the interrupt */
}
return exit_code;
}
I debugged & found that error comes from this code execution in main() :--
PINS_DRV_Init(NUM_OF_CONFIGURED_PINS0, g_pin_mux_InitConfigArr0);
Then i check the clock settings for PORT-D & FTM-0. And found that clock is not set :---
Following register PCC_PORTD & PCC_FTM0, bit-30 CGC is ZERO.
Inspite of initializing my system clock this clocks are not set :--
/* Initialize clock module */
CLOCK_SYS_Init(g_clockManConfigsArr, CLOCK_MANAGER_CONFIG_CNT, g_clockManCallbacksArr, CLOCK_MANAGER_CALLBACK_CNT);
CLOCK_SYS_UpdateConfiguration(0U, CLOCK_MANAGER_POLICY_AGREEMENT);
Please suggest how to get rid of this error. I have attached my sample project.
Any help from your side will be appreciated.

Dinesh
Anyone who can suggest on this query ?
As I am trying to create Core_clock using external oscillator .. 8 MHZ connected on this Eval board S32K144EVB
I debugged the project & found :---
What i found following function call return status : STATUS_ERROR :----
CLOCK_SYS_UpdateConfiguration()
Inside this function following line gives error :--
ret = CLOCK_SYS_SetConfiguration(g_clockState.configTable[targetConfigIndex]);
It seems some issue with my configuration of clock that's why this function failing :--
ret = CLOCK_SYS_SetConfiguration(g_clockState.configTable[targetConfigIndex]);
Please suggest what I have made wrong settings, so that i can resolve this error.
Regards,
Dinesh
Hi @Dinesh_Guleria,
The CLOCK_SYS_UpdateConfiguration() function returns STATUS_ERROR here:
clock_S32K1xx.c
If you open HSRUN configuration, you will see that the system clock frequency in your HSRUN configuration does not meet the max allowed values.
Regards,
Daniel
