Hi Michael,
Yes, this is the way to go!
Actually NuttX already supports loading ELF from SDCard or USB Thumb
Driver (called "pendrive" in some countries).
I created a video demonstrating it, see here:

Also there is a PR in progress that will extend
Hi Alan,
I am really happy to got your interest. Replacing the Pi with an EsPiFF
with Nuttx is also our intention.
The SWD for the RP2040 is alredy broken out, on J5, pin 6(SWCLK) and pin
8 (SWDIO). The connector J5 is a DF11, 2mm spacing connector, we will
add cables with 2.54 Duponts on
Hi Michael,
Congratulations! You created a really great board!!!
I'm sure that many people here will be interested on it, those who are
really interested to contribute.
The idea of using RPI form-factor is really good. Actually we were
discussing about the idea of creating some RPI-like board
Hi,
-The external wifi antenna is the best option. I also agree that wired
ethernet is essential and preferred in an industrial application. So
thats fine.
-SD cards are very unreliable and to achieve their goal (be usable on
desktop computers), they have to use FAT filesystems, which are
Hello Sebastian,
thanks for your interest! About the Wifi antenna: The used
ESP32-WROVER-I has the wifi signal connected to the uFL connector by
default, the PCB antenna would request to solder a 0 Ohm resistor, to
use it. Because of the space limitations, we drop the idea to use the
PCB
Hi,
A devboard with no jtag makes no sense for me! When you have a hw
revision with both the esp32 and the rp2040 debug ports broken out on
HE10-1.27mm headers (or pads if space is tight), I'm interested to get
one :)
The internal wifi antenna close to the IO header metal pins is also not
Dear Nuttx developers,
we have developed the EsPiff (ESP32+RP2040 on the Raspberry Pi Form
Factor), a open source board to replace RasPi's and there clones, where
the high processing power and/or Linux is not needed, but stability and
the reuse of RasPi HATs are required.
