Unified bootloader for S32K344

[RajaJayaraman]

Hi,

I started recently with S32K344 Eval board and would like to know, do you have the Unified bootloader for S32K344 device already ? If not, when it is expected to be released ?

Thanks !

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,

Then I uart for debug ，find program strike at erase and write status function （specific is inside  C40_Ip_Compare function is C40_Ip_SynchronizeCache）. I don't know what reason and what should i do.

Hi there,

I'm currently evaluating the S32K344 on RDK344BMU_V20 BMS reference design. Are you able to provide me with the unified bootloader for the S32K344 so I can evaluate this functionality?

Kind regards,

Matt

[RajaJayaraman]

Hi Matt,

I have not received the bootloader from NXP yet, we should ask this question to NXP.

Best regards,

Raja
