Nuttx not installing correctly on the Particle Photon.

[greg5678]

Here are the commands I've used.

$ mkdir nuttxspace
$ cd nuttxspace
$ git clone https://github.com/apache/incubator-nuttx.git nuttx
$ git clone https://github.com/apache/incubator-nuttx-apps apps
$ cd nuttx
$ ./tools/configure.sh -l photon:wlan
$ make menuconfig

Another post said it better than I ever could. "Application Configuration → Network Utilities → Network initialization → WAPI Configuration set SSID and Passphrase corresponding to the Wi-Fi AP (Router) save, exit"

$ make
$ sudo dfu-util -d 2b04:d006 -a 0 -s 0x08020000 -D nuttx.bin

The device just continues to blink yellow and if I unplug neither the status light nor the D7 LED comes on, but I can still put the device in DFU mode (which causes it to blink yellow).

Hi @greg5678 sorry I only saw your issue today. Did you search to know what the yellow blinking means? Last time I tested Particle Photon was with NuttX 8.x, I need to test it again with new version.

[greg5678]

Thanks for replying, @acassis. Yes, so it blinking yellow means it's in DFU mode. I made a couple of posts about it on Particle's forum, and they recommend I downgrade it to 0.5.5, but that didn't help.

Any idea what might be the issue?

Hi @greg5678 I did a little investigation today and it seems that some modification broke the network support:

ABCDF
netdev_register: Registered MAC: 00:00:00:00:00:00 as dev: wlan0
netdev_ifr_ioctl: cmd: 1794
netdev_ifr_ioctl: cmd: 1796
netdev_ifr_ioctl: cmd: 1800
netdev_ifr_ioctl: cmd: 1818
nsh_telnetstart: Starting the Telnet daemon
telnetd_daemon: Accepting connections on port 23

You can see it if you enable: Device Drivers -> Serial Driver Support -> Serial Console = USART1 and Build Setup -> Debug Options -> Enable Debug Features (En. Error, Warn and Info) and Network Debug Features (Error, Warn and Info).

Then use a USB/Serial 3.3V connected to TX/RX/GND pins of the board and use a serial console terminal (i.e. minicom) configured to 115200.

If you download some previous NuttX version you will see it was working, I suspect some recent modification on network generated this issue.

Ok, I found an old version that worked fine for me. It was from 2018! For some reason DHCP didn't work with my router, then I setup it fixed to 192.168.0.16. You can find my saved defconfig here: https://pastebin.com/raw/V33BnMVv If you want to test the binary, just flash it on your board and configure a wifi router (or phone with hotspot) with SSID: DLINK and password: dlinkphoto More info here: https://acassis.wordpress.com/2022/09/10/nuttx-binary-to-test-particle-photon-board/

So, I downloaded nuttx 8.2 and did the same thing as before, but the device just keep blinking yellow and when I pressed the reset button the device's status LED stayed dark like before. I then took the firmware you gave me and it gave me the same results. I created the Wi-Fi network, but I never saw the device appear. As the yellow light blinks the D7 led is dim which means it hasn't exited the bootloader.

from the Particle forum: "The device won’t reset when you use the DFU command to flash nuttx.bin, you’d need to manually reset the device, so that’s expected.

And are you sure nuttx isn’t running? Since it would need to manually control the status LED, it very well may not do that. And D7 doing off is a good sign. When the bootloader is running, the status LED is on dimly. It going off indicates that the bootloader exited and it probably jumped to the nuttx code."

Flashing your firmware:

$ md5sum nuttx.bin

sudo dfu-util -d 2b04:d006 -a 0 -s 0x08020000 -D nuttx.bin

Update:

Okay, after flashing Nuttx 8.2 the device seems to connect to the network, but I'm unable to connect to it via telnet and then it disappears after a minute or two.

Update 2: It works. :)

So, since the network support is broken on the newer versions of Nuttx will that get patched eventually?

[acassis]

@greg5678 I missed your message, probably because other priority tasks. Please refer to this issue: https://github.com/apache/nuttx/issues/8839 I got NuttX 9.0 working on Photon board. Maybe you could help too to find each patch broke it.

BTW, I will close this issue because it is duplicated now.
