Using SRC_BOOT_CFGx pins as GPIOs?

emilzachariageo — Fri, 17 May 2019 13:12:25 GMT

Hi Team,

Can we use the SRC_BOOT_CFGx pins as GPIO pins or some SPI dedicated pin?

Are they sampled only during the boot time?

If so, is it okay if we provide the required pull-ups and pull-downs to these pins to set required boot option?

Thanks in advance.

Emil

Hi Emil

yes this is possible, one can look on sect.2.3 Bus isolation circuit
