S32K144 Bootloader Example

Hi all,

I want to share S32K144 bootloader example (based on AN12218SW : S32K148) using S32K144EVB

 

This example includes :

1. Bootloader interface : Tool to download User Application to S32K144 when running bootloader

2. Bootloader_b11 : Bootloader project

3. bootloader_app_b10 :  User Application project

 

How to use :

I) Step 1 : to flash Bootloader (BootLoader_b10.elf) to S32K144 (through USB micro connector)

 

 

II) Step 2 : Bootloader will wait in 10 seconds for you click "download" user application 'bootloader_app_b10.srec' file through Serial_Bootloader_Interface.jar tool (Select Baudrate = 19200). If not, Bootloader will run forever in for-loop (user application is not downloaded into S32K144)

 

  

 

Note1 : After User Application is downloaded into S32K144, Bootloader will automatically jump to user application (RED LED and GREEN LED blink alternately)

Note2 : If you re-build User Application in User Application project, you need to modify a little srec file (bootloader_app_b10\Debug\bootloader_app_b10.srec)

Good luck .. ^_^
