Hi,
I'm developing a device using an ESP32 with NuttX that needs to
broadcast a beacon/advertise on both bt4 and ble5 (and also do radio
sharing with wifi). I've done some work with ble 5 with ESP-IDF and
understand a little about bluetooth. Unfortunately, I can't se
Hello,
Has anyone worked on setting the FRDM-K64F board up as a USB host?
The k28 & k66 devices support USB Hi speed mode, while the k64f device
only supports USB Full-speed (and Low-speed) OTG operation.
Kind regards

been looking for an excuse to test NuttX on this chip, so I took
a look and added the missing support you can see it here:

The main issue was the clock was not being configured correctly. The
k28 has a different default PLL frequency so needs

Kind regards

on how to debug?
The k64f has two modes of USB clocking, derived from PLL clock or
IRC48 clock sync'd to incoming USB data. I started by using clocking
derived from PLL.
I have modified a number of source files based on the Kinetis k28,
which has a configuration for usbnsh:
nuttx/b
cking derived
from PLL.
I have modified a number of source files based on the Kinetis k28, which
has a configuration for usbnsh:
nuttx/boards/arm/kinetis/freedom-k64f/include/board.h based on
freedom-k28 board.h. Modified to set MCG Frequency (PLLOUT) to 96 MHz
and included settings for USB c
