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
