HardFault issue of FLS module occurs after enabling PIT

[zp001]

Hello NXP team,

I'm using Fls module which is RTD 2.0.1, if we enable PIT, system will crash, here is the call stack:

Fls_Example_S32K344.elf

I'd like to know why it went wrong.

Thanks!

Hi Robin,

Here is my FLS sector configuration:

static const Fls_Flash_InternalSectorInfoType * const FlsConfigSet_VS_0_aSectorList[17U] =
{
&FlsSector_dflash0_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S000 */
&FlsSector_1_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S001 */
&FlsSector_2_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S002 */
&FlsSector_3_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S003 */
&FlsSector_4_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S004 */
&FlsSector_5_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S005 */
&FlsSector_6_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S006 */
&FlsSector_7_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S007 */
&FlsSector_8_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S008 */
&FlsSector_9_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S009 */
&FlsSector_10_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S010 */
&FlsSector_11_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S011 */
&FlsSector_12_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S012 */
&FlsSector_13_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S013 */
&FlsSector_14_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S014 */
&FlsSector_15_FlsConfigSet_VS_0_sInternalSectorInfo, /* FLS_DATA_ARRAY_0_BLOCK_4_S015 */
&FlsSector_16_FlsConfigSet_VS_0_sInternalSectorInfo /* FLS_CODE_ARRAY_0_BLOCK_0_S104 */
};

I used 16 sectors of data flash and 1 setor of code flash, and the code text is also stored at block 0(0x40000000).

if we run code from block 0(start address:0x40000000), in the meantime, I try to write data into sector which belong to BLOCK0, that is not allowed?
