hi !
I have a question about FS65xx when I download program.when I use FS65xx to supply power MCU in normal mode(not in debug mode),if i want to downloade a new program by using bootloader ,what should i do? And now I use IO port to pull up DEBUG pin in bootloader ,and release it in APP when download process is finished. Because I don't want to feed dog in download process. How should I operate FS65 in bootloader and it will meet functional safety requirments.
Thanks!
Hello,

How to download program in normal mode(not in debud mode,e.g thru CAN )?thanks
"The watchdog refresh can be disabled during INIT_FS state of the fail-safe logic to allow programming without taking care of the watchdog refresh. INIT_FS can be entered by a reset request with RSTB_REQ bit in SF_OUTPUT_REQUEST register."The above is described in the guideline.
