S32K344 TBOX- Can Bootloader Implementation

[JosePineiro]

Hello,

I am using S32K344 TBOX and I want to implement unified can bootloader sample "S32K344_CAN_Bootloader_RTD2d0". I have installed S32K3 RTD AUTOSAR 4.4 Version 2.0.0, the program compile with no errors and warnings:

I have connected 3 Peak Can 2, 4 and 5 but in the sample the output is configured for output 0. I don´t have Tresos project to change it and generate the new configuration. How can I do it?

The link where I download the example is:

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,

Thank you for your help @Robin_Shen, we did the changes necessaries.

Now I´m testing communication with Peak Can as you can see below:

The messages is 0x748 (id) 02 10 03 but we don´t receive anything, the bus is heavy and the program is running a while true in the function "HardFault_Handler". Am I doing something wrong?

[JosePineiro]

I have debugged the program and the exceptions hard fault jump in this point:

Should I configure anything in the clock or something else?

Hi

CAN0 of S32K3-T-BOX is connect to J33 pin 4(CAN0_H) and pin 14(CAN0_L).

You don't need EB tresos Studio, you should be able to change the configuration of S32K344_CAN_Bootloader_RTD2d0 in S32CT Configuration Tool.
