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."
