The 343026 spec recommends SPI2_MOSI to be used for some recovery within the community, even though No Connect is recommended.
https://community.cypress.com/message/158986#158986
Then, it is a description that you must use. Is there a problem if SPI2_MOSI remains NoConnect as specified in 343026?

Hi KeOn
Basically, it is a PIN used inside CYBT-343026-01, so Open / Hi-Z is the basic.
However, you need to control it for recovery only when the contents of the built-in Serial Flash become invalid.
At this time, use Open drain to lower it to Low.
Normally, it is unlikely that the Serial Flash will be rewritten, so No Connect is recommended,
but the Serial Flash is recommended when the FW update fails in the field, when repairs are made,
or when debugging in the lab during development. If the contents of are incorrect, r
ecovery support may be required when reprogramming Serial Flash.
Thanks
