SPI Flash boot invalidation on startKIT

Post by Kasebe »

I tried connecting M(MODE[2] and MODE[3]) with G(GND=Low) on startKIT TP1, but SPI Flash boot is executed.

How can I invalidate SPI Flash boot?

The startKIT has an image burned in the OTP to change the standard behavior. This allows it to boot from non-standard flash pins. The OTP program also automatically determines whether to boot from SPI/JTAG.

Thank you for your answer.

I gaved /CS=High on SPI Flash pin directly and it can be invalidated.

(Manufactured program from OTP booted.)
