I want to be able to reprogram my board using XCP. As a result I have a boot image that uses the first 1MB of PFLASH and and application that starts 1MB up, so address 0x00500000 or FLASH sector 128.
I can switch back and forth between the images and send the flash data when running the boot image. However if I try to erase block 128 I get a hard fault.
I have been following this thread
Solved: S32K344 C40 IP Hardware Fault Problem - NXP Community
Which talks about running the erase and write C40 routines in RAM. I do not understand why I would need to do this as the boot image and associated C40 routines all live well within the first 128 flash blocks.
However I have attempted to modify C40_Ip.h as suggested in the thread as in the example below
#if ( 1 == C40_RAM_CODE_ENABLE )
/* ram code start */
#define FLS_STOP_SEC_CODE
#include "Fls_MemMap.h"
#define FLS_START_SEC_RAMCODE
#include "Fls_MemMap.h"
#endif
C40_Ip_StatusType C40_Ip_MainInterfaceSectorEraseStatus(void);
#if ( 1 == C40_RAM_CODE_ENABLE )
/* ram code end */
#define FLS_STOP_SEC_RAMCODE
#include "Fls_MemMap.h"
#define FLS_START_SEC_CODE
#include "Fls_MemMap.h"
#endif
However this does not compile
C:/NXP/S32DS.3.5/S32DS/software/PlatformSDK_S32K3/RTD/BaseNXP_TS_T40D34M30I0R0/include/Fls_MemMap.h:6865:10: error: #error "MemMap.h, no valid matching start-stop section defined."
6865 | #error "MemMap.h, no valid matching start-stop section defined."
| ^~~~~
I would like to understand why I would need to do this and if I do what I need to do to make the compilation work?
