Hi, First of all, sorry for lengthy post and that I ask a lot of things at once, I am very new to linux and this would be my first real experience. I am trying to set up home automation and home assistant server. As I am just getting started to learn all the ropes, I thought about what could be used for sečrver and I remembered that I have an old T9 android TV box see the attachement, I read through this thread and tried to follow the instructions throughout the posts. I burned the armbian image to sd card, which insterted into the sd slot on the T9 board, however I am unable to get the board to boot from the sd card. The box boots normally into android, when no SD card is insterted. When the card is inserted, nothing happens and the box does not turn on at all. It may be a big ask, but would someone be able and willing to help me find out the next possible steps? I feel a bit overwhemed as I am not very knowledgable in this field and unsure how to follow the instructions, or better said, I am not sure if I am following the instructions right. Thank you!

If you need an own build for some reason, you should be able to debug it as well. Why does it fail, others cannot know that from that screenshot. Also you yourself cannot. You need serial console etc, look into bootprocess of RPi, examine files and logs. In general it is rather simple compared to other SBC's, but still you need to do that yourself. It also might be an (additional) problem with you Pi or some SD-card adaptor etc/ Why can't you not use the standard available image? You can remove/tweak/add from there as well.

Ubuntu I see. That I do not have running, so cannot speak from experience.

But I already tried that and it didn't work.

Thanks for the feedback. This is welcome 👾 I'm currently fiddling with Wifi for the 6.18 kernel. No good karma: the adapted bcmdhd sdio wifi from the Spacemit kernel 6.6 was removed from 6.18. So I'm using the bcmdhd extension instead, as it's done with OrangePi 5, based on the github/armbian/bcmdhd-dkms repo. That one has ALLWINNER changes under the #ifdef CUSTOMER_HW_RK (probably Rockchip origin). I need to re-add SPACEMIT changes. Also, I need to revert a Wake-on-WLAN change submitted by Spacemit to RFKILL in order to get the necessary Interrupt init called. Bonus: OPi5-edge also uses that extension driver but does not compile b/c a PR for 6.17 on bcmdhd-dkms from October was ignored. Will need time 🤪 LG // Sven-Ola
