Hello,
I have downloaded https://www.nxp.com/docs/en/application-note-software/AN12218SW.zip and it works successfully. There is one issue. Bootloader interface sends SREC line data at least 50ms intervals. It is huge duration for big SREC files. For instance, sending 200KB SREC file takes more than 4 min. Can you share source code of Bootloader Interface or is there faster version of it?
Best regards.
Hi,
I'm afraid there is no possibility to run the bootloader and the user application at the same time.
However, the S32Kxx bootloader AN12218 can be useful, but there is needed to jump from bootloader to the application.

Hi,Diana,
Thank you for your reply. I have read the document and the project.
But it need power cuts to upgrade the app without timeout.
And I need to upgrade the app without running out of the power.
