FRDM-S32K344 manual error

fae — Fri, 24 Jul 2026 09:13:53 GMT

Hello,

There is a mistake on page 11 of FRDM-A-S32K344 development board manual (UM12406) . I'm posting this comment for the community and for anyone who runs into the same problem I did.

"Specifically, resistor R43 is populated by default to keep the FS26 in debug mode. To enable normal mode, R43 must be removed and R42 must be populated instead."

Should be:

"Specifically, resistor R43 is populated by default to keep the FS26 in debug mode. To enable normal mode, R43 must be removed. ~~and R42 must be populated instead~~."

or:

"Specifically, resistor R43 is populated by default to keep the FS26 in debug mode. To enable normal mode, R43 must be removed. R42 must be populated to enter in OTP emulation mode."

Thank you for the report!

When R43 is removed and R42 is populated, the voltage of FS26_VDEBUG will be within the VOTP (OTP emulation mode) range of the FS26 DataSheet. Therefore, I agree with your point of view, and I think the second statement is more comprehensive.

Let me contact the author to report this issue.

Best Regards,
Robin
