HSE安装后，SWAP切面成功后 运行10s左右程序会发生 HSE_SWT_RST ，是什么原因

[1446311191]

After HSE is installed and the SWAP section is successfully executed, the program will encounter HSE_SWT_RST after running for about 10 seconds. What is the reason?

S32K312

HSE clock 60M

Hi

1. Please tell me the RTD version and HSE version and sBAF version (0x4039C020). We recommend updating to the latest versions: HSE_FW_S32K312_0_2_55_0_D2502.exe and SBAF_S32K312_0_0_15_0.exe.

2. This is a known behavior of the HSE, typically caused by an incorrect clock configuration. Please refer to the following community post: S32K312 HSE_SWT_RST issue. It contains helpful information that should assist in solving your issue.

3. Please check the HSE_STATUS_INIT_OK status before MCU_Init/Mcu_InitClock. Otherwise, it may trigger issue.

#define HSE_STATUS_INIT_OK_BIT                                  (1U << 24U)

while ( FALSE == HSE_CheckStatus(HSE_STATUS_INIT_OK) )
or baremetal codes:
while ( FALSE == ((*(uint32_t *)(0x4038C104)) & HSE_STATUS_INIT_OK_BIT) ) 
{
    ;
}
/* MU0 Base address:0x4038C000, FSR offset address: 0x104, 
Bit24 in FSR:HSE_STATUS_INIT_OK */

4. Please check if the clock configuration matches Table 158. Option B - Reduced Speed mode (CORE_CLK @ 120 MHz) of S32K3XXRM(Rev11).

Best Regards,
Robin
