Hello,

I am trying to run the the firmware update in S32K144. 

Wthout any modification, i build and downloaded the memory parition project and bootloader in one S32K144.

I build and downloaded the memory parition project and gateway in other one.

The gateway is sending 0x151515 with id 0x200, the other one with the bootloader is working but not responding back? 

i tried to reset the bootloader with the reset pin. 

i tried to reset the gateway also and press one the switch buttons, i debugged and made sure its jumping, and also with PEAK CAN i can see the 0x151515. Still not the bootloader S32K not responding, any hints please? 

another question: where can i see the S32K144_blue_LED_pic linker file? or it is not possible?

Thanks! 

Best regards,

Nader

Hello Nader,

I'm very sorry for the delay.

Unfortunately, I have not second board here for testing this example, however, have you set the correct baudrate and reset the bootloader board after that? "Open a serial terminal, select the OpenSDA virtual COM and set the terminal to a baud rate of 9600."

There is no linker file for the S32K144_blue_LED_pic, however, but as we know, the fw v1 starts at 0x2000 address and ends at 0x40000 address.

So, the linker file can look like this, but I did not test it.

/* Flash */
m_interrupts (RX) : ORIGIN = 0x00002000, LENGTH = 0x00000400
m_flash_config (RX) : ORIGIN = 0x00002400, LENGTH = 0x00000010
m_text (RX) : ORIGIN = 0x00002410, LENGTH =0x3DBF0  /* 0x40000-0x2410 */

Best regards,

Diana
