You are going down the wrong path. You should start here with understanding the Armbian build framework: https://docs.armbian.com/Developer-Guide_Overview

I would suggest you to download clean Debian minimal image and proceed this way: https://docs.armbian.com/User-Guide_Armbian-Software/HomeAutomation/#home-assistant EVCC can be installed this way - official Docker container: https://docs.armbian.com/User-Guide_Armbian-Software/HomeAutomation/#evcc How to deal with EVCC from HA, no idea. This is application level knowledge and I am just an average user of HA. I assume addon will want to connect to the service which runs on some IP address and some port. IMO this part is similar as official HAOS image. Current application images are not yet rebuild with latest stable base, so until then its better going clean Debain + armbian-config way.

CONFIG_PREEMPT_RT=y. I was hoping to use the OrangePi5 Pro - with Linuxcnc - for machine controls - This would require predictable response times for precision cutting routines. The kernel build settings in the current release do not include the Setting for PREEMPTIVE_RT. Debian for X86 defaults to having it setup to support a Fully Preemptive mode. I am wondering why this hasn't trickled down to SBC builds. Byte2bot sells a shield card for converting the Pi 20 pin header to a Parallel port for connecting to CNC motion control cards - roughly $50 without having any manual wiring. Really slick - but at the moment - its would be good for Raspberry pi 4 and 5 as they have the Realtime kernel build available. I have a Tower PC with PCIe parallel on debian bookwork setup for machine control for a milling machine. So the Orange_Pi_5 is a much better solution . Please let me know how if I am on the correct track. I will copy the config file to the .config file in the kernel build directory -- This should be found in the /boot directory or the /proc directory - and add in the PREEMPT commands for fully PREEMTIVE that I found listed in the Kconfig file. Then I have to figure out where to place the orangepi5pro.csc file you pointed me to. At that point I should try to find some reference material about the Preemption settings the make process is going to ask me about. make should complete, and then "make module_install" - Then "make modules" At that point - the build is done. I will have to sort out how the /boot files need to be modified. Sorry for all the questions - If there is some reference material - that is clear about the Image Uinitram the Armbian Environment - and other boot related topics please point them out.

update: if disconnect TX from USB-UART adaptor - then there is infinite output that changes every microsecond with more strings: ESC[1;47rESC[46;1H[ 45.827723][ Tible6] [dhd-wlan0] w l_ext_iapsta_evefs.readdy=1 (/system/etcb/init/hw/init.uo sr not foun db^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1Hnt : [S] Link UP with c8::ca:98^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1HESC[1;46rESC[46;1H ESC[1;47rESC[46;1H[ 45.827747][ T6] [dhd-wlan0] wconsole:/ $ ^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1Hl_notify_connect_status : wl_bss_conn.127^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1Hect_done succeeded with c8:ca:98 ^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1HESC[1;46rESC[46;1H ESC[1;47rESC[46;1H[ 45.843270][ T6] [dhd-wlan0] wl_notify_connect_sonso le:/ $ c^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1Htatus : wl_bss_connect_done succeeded127|^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1H with c8:7f:54:e0:ca:98 vndr_oui: 00-90-127|^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1H4C 00-0C-43 00-0C-E7 ^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1HESC[1;46rESC[46;1H ESC[1;47rESC[46;1H[ 45.881840][ T165] type=1400 audit(1699712132.610:14conssole:/ $ ^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1H4): avc: denied { open } for comm="FD655_Demo" path="/sys/class/fd655/fd65console:/ $ ^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1H5_vpause_127|y^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1Hflag" dev="s127fig=|^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1Hysfs" ino=19647 sc[ 82.040633][ T386] read descriptors^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1H[ 82.040698][ T386] read strings^MESC[1;46rESC[46;1H ESC[1;47rESC[46;1H[ 82.043097][ T1] init: processing action (sys.usb.config=adb && sys.usb.configfs=1 && sys.usb.ffs.ready=1) f82.045159][ T1] init: Co mmand 'symlink /coESC[46;159HnESC[46;159HfESC[46;159HiESC[46;159HgESC[46;159H But still no active shell session

Werner - thanks - I did check the community and only found builds for 6.1 -- I did a build and had added three lines in the .conf file CONFIG_ PREEMPTICE_RT=y CONFIG_PREEMPTION=y and CONFIG_PREEMPT=y as I recall. did the "make" "make modules_install" and then the "make module" and there were a string of questions - during the make about some of the pre-emption options, which I was unprepared to answer. Not worried about those. I was concerned that the modules_install and the module make commands were installing the necessary routines. I do not understand how the orangepi5pro.csc file gets incorporated into the build process. I was on an Orangepi os to run the krtnrl build. Now moving back to Armbian 6.1.115. I am downloading a Armbian community supported 6.1.115 download for orange pi pro. I will then download the rockchip-rk3588.conf file - and the orangepi5pro.csc file - not sure where the board config file goes and how it ties into the kernel build process - might need a pointer for that Jim
