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,
Jon Ander Amante Jorge
Hello @Djuric,
There is just this bootloader for S32K344:
https://community.nxp.com/t5/S32K-Knowledge-Base/Unified-bootloader-Demo/ta-p/1423099
But the MCU supports AB Swap via the HSE_FW services.
In the active block, you can have also a routine that programs the passive block, and once the passive block is flashed, call the HSE_FW service to swap the blocks.
In the S32K3xx Reference SW,

there is this official demo:
It is rather old, please read the release notes.
Regards,
Daniel
