Hi,I'm using arduino ide and not shure how can I enable "CONFIG_TWAI_ISR_IN_IRAM", can anyone help me?

thanks!

I don't undestand at all how does it work the function "gpio_deep_sleep_hold_en", it hold ALL pins in deep sleep ? or just the ones set prevoiusly by "gpio_hold_en(gpio_num_t gpio_num)". I need to Hold just one GPIO during deep-sleep, is it possible?

thanks!!

Hi, I'd like to know if its possible to use the flash API to connect an external flash(not shared with main flash) in dual mode and not use WP and HOLD, I have left only 4 pins and I don't wanna use an SD card beacuse of the vibration environment.

thanks
