How does the boot process work?

How can we program the external flash?

As I understood, we should define the boot mode as a serial downloader to program the external flash through the NXP MCU (is that the only way to program the external flash?);

then, we need to change the mode to boot from fuses/internal boot so the NXP can boot after power-on.

Is it going that way?

Hi，
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1）How does the boot process work?
-- Please refer to the figure FlexSPI NOR boot flow in the RM.
2) As I understood, we should define the boot mode as a serial downloader to program the external flash through the NXP MCU (is that the only way to program the external flash?);
-- No, it's not the only way, you can use the debug tool like the Jlink to program the image to the external flash directly, without forcing the MCU to enter Serial Downloader at first.
Have a great day,
TIC

Thank you

So when we program the external flash via Jlink we can define permanently the boot mode as "boot from fuses/internal boot", and program the flash even when the boot mode is on "boot from fuses"?

When we program via serial downloader we must have the internal boot option? (because the eFuses aren't rewritable)

Thank you!

what debuggers can we use besides the Jilnk to program the external flash through the NXP MCU?

Hi,

We will use MCU-Link Debug Probe as a debugger to program the external flash and to burn fuses.

https://www.nxp.com/design/microcontrollers-developer-resources/mcu-link-debug-probe:MCU-LINK?SAMLart=ST-AAF0E3YJDJej%2BJVBprc7Vu5rkUdez9KlW7d2EDc31otR%2BbD6Fdeoe2%2Fm

We will use it with SWD, not JTAG. Will it work fine?

Do you provide a cable from the debugger (J6 connector) to the NXP board that supports only the SWD? (we want to use on our board a connector with less pins, and smaller dimensions)

Thank you

I don't see the cable ends in the picture below.

Can you please send its datasheet?

Hi,
Thanks for your reply.

-- It's just a cable, it doesn't have the datasheet.
