Anyway to speed up the boot up time

[rith87]

From the getting started guide:

Q : How to short the booting time (include awakened from deep sleep) ?
A : RF will do self-calibration by default during booting. But since esp_iot_sdk_v1.3.0, users can
configure RF to do calibration only at the first-time power-on, and store the calibration parameters
into the flash, so that they don’t need to calibrate RF again when the chip is booting up.

I have an ESP12F and put esp_init_data_default.bin at 0x3FC000 but there was no difference in boot up times.

Bump. Is there really no way to speed up the boot up time (rather than the deep sleep wake up time)?

[rith87]

Or if there is absolutely no way to do so, can the Espressif folks let me know?

Based on this repo at https://github.com/pvvx/SDKnoWiFi, it does not seem like a hardware limitation.

But this post at http://www.esp8266.com/viewtopic.php?f=6&t=9653&hilit=deep+sleep+wake+up+time shows that deep sleep wake up times using the deep sleep API is >200 ms. So, I guess there's no way to further reduce the wake up time (without building some other binary)?
