FS26 deinit

YBoughallad — Mon, 06 Feb 2023 12:56:10 GMT

Hello,
I wanted to ask if there is a proper/safe way to deinit the FS26.
my use case is :
i get the FS into normal mode in the Bootloader software. But if I jump to the application, I cannot reinitialize it again as it is already in Normal mode. I want to set the FS26 back to init FS state and maybe disable the watchdog until it get initialized again in the Application.
is this possible? if not, is there a recommended procedure for this case?

Yes, that is possible with an SPI command called GOTO_INIT in FS_SAFE_IOS_1 register

Regards.

thank you for your response.

is this the only thing I need to do? how about the watchdog, will it be disabled until I initialize again the SBC?

Hello,

Please see this post: What Happens when you dont close the INIT_FS Phase before the 256ms timeout on the FS26 watchdog

Hope it helps.

Hello,

A little bit support,

In the BOOT,

INit with disabled watchdog duration.

Jump to APP

Goto InitFS again by write GOTO_INIT bit

Initialize FS26 again within 256 ms after you switched back InitFS state.
