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,

After reading it, I still don't understand the title question。

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.

Hi !

There are two kinds of MCU Platform,  they are MPC5775E and Infineon Aurix TC38x.

When using the two platforms, is there any difference in the function usage of fs65 ?

Thanks!

  When fault occurs  ,  it can only be cleared by watchdog refresh ?

过压故障产生后故障错误计数器会增加,这时候应该怎么清除故障呢

你好!我们在第一次烧写程序的时候,这时候即不能通过MCU去控制debug引脚,也不能实现正常喂狗,应该如何做操呢?

这样只能自己做外围的电路,上电默认满足进入debug模式

When we download program ,we use IO port to pullup Debug pin and release the pin in application  after download process has been finished, Does this approach meet functional safety requirements?
