Dear @陈简陈 @lukaszadrapa ,

I am trying to use this bootloader as recommended from openTicket Support team.

> Flashing the "MPC5744P_CAN_Bootloader.elf" file to board

> Open device of GY8507 by Demo_CAN app successfully

> Send "MPC5744P_CAN_Bootloader_APP_LED_Toggle_Align_8.s19" file by GUI application.

> CAN Communication stopped.

> Reset Hardware devkit

> Send file again, No communication RX back from board.

Could you help advise what settings I should fix to up-running this demo ?

Best regards,

Narudol T.

Hello, I have find some problems. About the flash boot loader-project.

/* get the content(reset/start function address) of the user application project from its boot_reset_vector address*/
#define APP_StartAddr (*(uint32_t*)0x00FA0004)

I think the value is wrong . Because in the flashbootloader-project, 0x00FA004 means the cpu0_reset_vec of the bootloader not app. 

It should be 0x00FB0004 defined in the app-project . The app-project has defined it in its link file.

Could you help me check it ? Thank you very much.
