  @CAP-33 This is like a DOS crosslink error on the FAT file system. To fix it you need to install the dosfstools. edit /etc/opkg/distfeeds.conf and uncomment line 1 opkg update opkg install dosfstools /usr/sbin/fsck.fat -f -l -a /dev/mmcblk0p1

  @Carey-Capaldi You can get mqtt (and a whole lot more) for micropython with the micropython-lib package. Just updated the Omega2 Dash guide with a new section on installing micropython-lib Let us know how it goes!

  @Callum-Jones I'm not sure if anybody has already designed an enclosure, but if you're so inclined, you can use the board measurements to design your own. See this post for info on where to find the board measurement files.

  Using the Expansion Dock with Omega2, running FW, 0.3.2 b233. Please see the image that shows the termination of pins. Let us choose PWM CH1, marked as pin 19. Let us check the current GPIO configuration. root@Omega-CCC9:/# omega2-ctrl gpiomux get Group i2c - [i2c] gpio Group uart0 - [uart] gpio Group uart1 - [uart] gpio pwm01 Group uart2 - [uart] gpio pwm23 Group pwm0 - [pwm] gpio Group pwm1 - [pwm] gpio Group refclk - refclk [gpio] Group spi_s - spi_s [gpio] pwm01_uart2 Group spi_cs1 - [spi_cs1] gpio refclk Group i2s - i2s [gpio] pcm Group ephy - [ephy] gpio Group wled - wled [gpio] =>pwm1 is configured for pwm root@Omega-CCC9:/# dht-sensor 19 DHT11 humidity: -255.000000 temperature: -255.000000 =>We get the wrong readings. Let us reconfigure pwm1.. root@Omega-CCC9:/# omega2-ctrl gpiomux set pwm1 gpio set gpiomux pwm1 -> gpio =>And verify pwm1 has changed to gpio. root@Omega-CCC9:/# omega2-ctrl gpiomux get Group i2c - [i2c] gpio Group uart0 - [uart] gpio Group uart1 - [uart] gpio pwm01 Group uart2 - [uart] gpio pwm23 Group pwm0 - [pwm] gpio Group pwm1 - pwm [gpio] Group refclk - refclk [gpio] Group spi_s - spi_s [gpio] pwm01_uart2 Group spi_cs1 - [spi_cs1] gpio refclk Group i2s - i2s [gpio] pcm Group ephy - [ephy] gpio Group wled - wled [gpio] =>Let us try again.. root@Omega-CCC9:/# dht-sensor 19 DHT11 humidity: 87.000000 temperature: 28.000000 => Put the pwm1 back to pwm root@Omega-CCC9:/# omega2-ctrl gpiomux set pwm1 pwm set gpiomux pwm1 -> pwm => And try.. root@Omega-CCC9:/# dht-sensor 19 DHT11 humidity: -255.000000 temperature: -255.000000 =>Once again, put pwm1 to gpio. root@Omega-CCC9:/# omega2-ctrl gpiomux set pwm1 gpio set gpiomux pwm1 -> gpio root@Omega-CCC9:/# dht-sensor 19 DHT11 humidity: 87.000000 temperature: 28.000000 => Try DHT22 root@Omega-CCC9:/# dht-sensor 19 DHT22 humidity: -255.000000 temperature: -255.000000 The DHT11 usually have 3v-5v operating range, with 5v5 specified as the max voltage. I used 3v3, not 5v; using 5v would probably damage the 3v3 inputs of Omega2. Also, the DHT11 I have already has the pull-up built onto the assy. Note: I have only 3 days hands-on with Omega. I could be wrong in the commands and config above.

  @crispyoz I would order Omega2+, the 32M/128M. In fact, I read that the (+) is the recommended model for development. Still, could procure only Omega2 locally. Digikey would take take 2 weeks or so. Finally, plan to use the SMD version, with custom PCB and power. Though I was able to boot RPi Zero W with cross-compiled OpenWRT 18.06.8 last week, Omega2S(+) will be easier from the hardware perspective. I am happy with the progress made in the past few days. Really appreciate all your help.. Thanks again.

  No more help is needed. A clean and complete recompilation of the latest version from the git repo did the trick.

  They are DEFINITELY not a scam! I've bought around 20 Omega2+s. Some direct, some through Mouser. some through DigiKey and some through their Australian distributor Core Electronics. My son has bought around 75 Omega2+s. We've also bought several Omega2+-Dash units each. Never a problem with ordering, delivery or support. Thoroughly recommended. Regards, Dave

  @Anil-bhaskar did you try the example rc.local @György-Farkas posted above? It may be that rc.local is functioning correctly but that the commands you are executing are not. You can post your rc.local If you are trying to start a daemon you may need to background it using & so it doesn't exit. I personally thing procd is more appropriate in that case.

  Hi, why don't you buy an Omega2-Dash? It comes with a 320x240 touch screen integrated with an Omega2S+. LVGL is provided for doing GUI etc. Cheers, Dave

  @Nathan-Guyette said in Stem cell differentiation architecture: What do you mean specifically that "/etc/rc.local is your friend"? See this article: http://docs.onion.io/omega2-docs/running-a-command-on-boot.html This might also be helpful: https://onion.io/2bt-custom-initd-service/

  @Jens-Modvig I wonder if the driver can differentiate between the two devices as the spec requires, but I believe SDIO will allow 3 on the same CS line. I'm very interested see your results.
