If there is a reserved BootLoader FLASH, where is it?
If not, is there any way to modify the BootLoader of the S32K344?

Hi,

 

Sorry for delayed response, we are overloaded due to summer vacations.

Let me share what we have:

There’s a support in HSE firmware. You can download HSE FW and HSE demo app, HSE OTADEMO for A/B Swap from S32K3 Standard Software and S32K3 Reference Software packages:

https://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=SW32K3-STDSW-D

https://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=SW32K3-REFSW-D

OTADEMO for A/B Swap uses this memory layout:

int_flash               : ORIGIN = 0x00400000, LENGTH = 0x00100000    /* 1024K */

int_flash_app           : ORIGIN = 0x00500000, LENGTH = 0x000D4000    /* 1024K - 176K (sBAF + HSE). Used for the application binary to flash (OTA) */

int_flash_Passive       : ORIGIN = 0x00600000, LENGTH = 0x001D4000    /* 2048K - 176K (sBAF + HSE) */

 

Then we provide Unified bootloader which can be downloaded here (no HSE is used):

https://community.nxp.com/t5/S32K-Knowledge-Base/Unified-bootloader-Demo/ta-p/1423099

This one uses this area for bootloader:

int_flash               : ORIGIN = 0x00400000, LENGTH = 0x00040000       /* 256K*/

And this for an application:

int_flash               : ORIGIN = 0x00440200, LENGTH = 0x007FFFFF - 0x00040200

 

If you have own bootloader, you can follow layout of Unified bootloader to use first possible location of IVT at 0x00400000.

 

Regards,

Lukas

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.
