S32k344 - Can Bootloader Hardfault and Busfault exception

JosePineiro — Tue, 22 Aug 2023 10:53:33 GMT

I have been debugging a hardfault in example "S32K344_CAN_Bootloader_RTD2d0" . I find out that the exceptions was no activated, after do it, busfault handler and memfault handler are called.

It seems to be a problem in the PLL because it is locked I dont know why, and the program is continuously doing the clock initialization until the exceptions appears.

There are some dummy functions in the example that I don´t change, must I complete any configuration in this functions?

for example this one

S32K344_CAN_Bootloader_RTD2d0 example is not developed based on S32K3-T-BOX. So you may need to modify the configuration according to S32K3-T-BOX.

For example: Crystal Y2 on S32K3-T-BOX is 40MHz. But in this example it is configured as 16MHz.

It is already changed, but still have the same problem.

Are there more configurations to do?

Please enable the clock gate of PLL.

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,
