First of all, thanks to Tomlin Tang and JaydenHsu,
Some users are looking for the flash driver source project of this routine, I summarize the process of making it as follows:
(you need to create a new project and add C40_Ip component to your project)
1.set Optimization Level to None
2.create flash image->HEX
3.modified the linker file.
4.copy and attribute "C40_Ip_StartSequence"
/* Including necessary configuration files. */
#include "Mcal.h"
volatile int exit_code = 0;
/* User includes */
#include "C40_Ip.h"
C40_Ip_StatusType __attribute__((section(".int_flstb"))) C40_Ip_StartSequence(uint8_t Operation,uint32_t TimeoutCnt)
{
uint32_t u32Timeout = TimeoutCnt;
C40_Ip_StatusType eReturnCode=STATUS_C40_IP_ERROR;
//erase cmd
if(0 == Operation)
{
/* One and only one ADATA register must also be written. This is referred to as an erase interlock write.*/
IP_FLASH->DATA[0] = 0xFFFFFFFFU;
/* Setup erase operation */
IP_FLASH->MCR |= FLASH_MCR_ERS_MASK;
/* Flash memory erase will be on a sector */
IP_FLASH->MCR &= ~FLASH_MCR_ESS_MASK;
}
//program cmd
else if(1 == Operation)
{
IP_FLASH->MCR |= FLASH_MCR_PGM_MASK;
}
else
{
/*error*/
}
/* start internal erase/program sequence */
IP_FLASH->MCR |= FLASH_MCR_EHV_MASK;
//check status
do
{
if(0U == (IP_FLASH->MCRS & FLASH_MCRS_DONE_MASK))
{
eReturnCode = STATUS_C40_IP_BUSY;
u32Timeout--;
if (0U == u32Timeout)
{
eReturnCode = STATUS_C40_IP_ERROR_TIMEOUT;
}
}
else
{
if(0U == (IP_FLASH->MCRS & FLASH_MCRS_PEG_MASK))
{
eReturnCode = STATUS_C40_IP_ERROR;
}
else
{
eReturnCode = STATUS_C40_IP_SUCCESS;
}
}
}while(STATUS_C40_IP_BUSY == eReturnCode);
if(STATUS_C40_IP_BUSY != eReturnCode)
{
/* Terminate erase operation */
IP_FLASH->MCR &= ~FLASH_MCR_EHV_MASK;
/* Terminate erase operation */
IP_FLASH->MCR &= ~FLASH_MCR_PGM_MASK;
}
return eReturnCode;
}
/*!

\details The startup initialization sequence is the following:

int main(void)
{
/* Write your code here */
for(;;)

if(exit_code != 0)

The above is the generation process of the flash driver for this routine, which is actually only a function "C40_Ip_StartSequence".
The bin content generated by the test is same
#S32K312 #ECUBUS
I'm using ecubus to do s32k312 bootloader,I haven't figured out the flash_driver of the separate code,Look at the code given by the nxp official and the ecubus project,I found that the address selected when brushing the flash_driver is 0x20000010,But the code and LD are 0x20000000,Why is there this deviation?
Hi, I am using the project "S32K344_Can_bootloader_RTD200" in the microprocessor S32K344. I want to download an application with the program of bootloader. I have achieved the jump from program to application but I have different questions. 1. I want to use #define EN_DELAY_TIME but when I uncomment the command in the folder "public_in", the program has different errors. My target to use "Backdoor", that is to say, I want to check if the program has to enter to bootloader or not. I don´t know the process and the different functions that I have to use to achieve the target. I want to use the function "Boot_CheckReqBootloaderMode(void)" but when I debug the program, it never enters to the "if". Could you explain me the process and the steps to achieve the target. I add different functions that I think are important. 2. I don´t know if I have to modificate the parameters of "static tJumpAppDelayTimeInfo gs_stJumpAPPDelayTimeInfo = {FALSE, 0u};". I have to change this structure ? You can see all structure in one of the next pictures. I need the reply as soon as possible since I have to send a project very soon.
Thank you for all,
