In the MAX32690 FTHR board.c file, we have:

const mxc_gpio_cfg_t pb_pin[] = {
{ MXC_GPIO1, MXC_GPIO_PIN_14, MXC_GPIO_FUNC_IN, MXC_GPIO_PAD_PULL_UP, MXC_GPIO_VSSEL_VDDIOH, MXC_GPIO_DRVSTR_0 },
{ MXC_GPIO1, MXC_GPIO_PIN_15, MXC_GPIO_FUNC_IN, MXC_GPIO_PAD_PULL_UP, MXC_GPIO_VSSEL_VDDIOH, MXC_GPIO_DRVSTR_0 },
};

Notice that P1.14 and P1.15 are set to VDDIOH.

But the data sheet says these pins can only be VDDIO:

"GPIO that support HyperBus as an alternate function are tied to the VDDIO supply and do not support VDDIOH supply selection."
