Unified bootloader S3SK344 flash problem

kimyonghak — Mon, 22 May 2023 07:34:13 GMT

I have problem when test #Unified bootloader at S32K344

when flash erase or write allways check Flash_IsFlashDriverDownload

if(TRUE != Flash_IsFlashDriverDownload())

but Flash_IsFlashDriverDownload() result always FALSE

at initalize routine FLASH_APP_Init() set Flash_SetFlashDriverNotDonwload()

and there is no call Flash_SetFlashDriverDowload() before

static void UDS_DoEraseFlash(uint8 TxStatus)

Can you advice how to make Flash_IsFlashDriverDownload() is TRUE ?

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,
