The custom-overlay. Now we are creating a Device Tree Overlay to use UART2 without RTS and CTS lines, because we need those gpios for manages other things, so our idea is to only use TX and RX lines as they are defined in Device Tree “imx6q-apalis-eval. my questions are: is it possible to include the three versions of the device tree in TorizonCore? is it possible to modify uboot behaviour so it The SoC level device trees define the driver node for each of these controllers which bind to the pinctrl-imx7 driver and defines the labels iomuxc and iomuxc_lpsr to give lower-level device tree access to the node. SP1 as a master and SP2 as If you’re on Torizon 6. I get the idea that I have to modifiy the pinmuxing for the extra 6 bits in the device tree, so I gave it a try by using an Overlay. The script can be run using the tdx-info command once inside the module: That brings me to changing the device tree as a way of telling the module, “Use SODIMM 101 as the uartb RTS pin” but I’m a bit out of my depth here and I cannot get it to work. However the link it gives is the same place that told me to use that command, so at this point I can’t get the device trees to do the overlay. I am able to get the eeprom to I followed this link Build Device Tree Overlays from Source Code | Toradex Developer Center to compile the DTO.
