Ask for FS26 drawing source document

ChandlerBing

Dear Support Team,

I’m engaged in software development based on FS26 SBC. The attached figure is quoted in our software development materials, yet I failed to locate its original official document.

Please help confirm which NXP FS26 document (datasheet / AN / safety manual / design guide) includes this diagram, and provide the corresponding document ID as well as figure chapter information.

Thank you very much for your assistance.

Regards,

Dear Lai,

I suppose that the document snippet you provided does not actually come from our FS26 documents. Instead it originates from the datasheet for the FS6500/FS4500 SBC family.

Since you are developing software for the newer FS26 SBC family, you should look into the FS26 software quick start guide (AN14492), FS26 implementation and behaviors (AN12995) or the full FS26 datasheet instead.

BRs, Tomas

Dear Tomas,
Thank you very much for your prompt clarification and guidance!
Besides, I have another debug issue to consult you.
Our system uses FS26 to supply FC7300 MCU. After FS26 enters FS_STATES_NORMAL_FS operational state, connecting J-Link will cause the RST pin to be pulled low multiple times consecutively, resulting in debugger connection failure.
In normal running mode with regular watchdog refresh, the reset issue never occurs.
Could you help analyze the root cause of this multi-reset phenomenon and share corresponding register configuration or hardware solutions?
Thanks again for your support.
Best regards,
Lai
