bt_boot_fail_04.txt

Interesting, pls post the failed boot.

sudo armbian-add-overlay /boot/overlay-user/bt_enable_full.dts Compiling the overlay Error: /boot/overlay-user/bt_enable_full.dts:23.34-35 syntax error FATAL ERROR: Unable to parse input tree Error compiling the overlay Ok, I guess the problem was in "GPIO_ACTIVE_HIGH" macros. So I changed them to "1". File has compiled and I begun to test the board. Two times in row the board booted ok, but next time BT has failed.

Ok, create a new dts /boot/overlay-user/bt_enable_full.dts /dts-v1/; /plugin/; &pio { bt_en_pin: bt_en_pin { pins = "PH1"; function = "gpio_out"; bias-pull-up; output-high; }; bt_wake_pin: bt_wake_pin { pins = "PH0"; function = "gpio_in"; bias-pull-up; }; }; &{/soc} { wcn_bt: wcn_bt@0 { compatible = "wcn,bt"; status = "okay"; enable-gpios = <&pio 7 1 GPIO_ACTIVE_HIGH>; // PH1 = GPIO225 wake-gpios = <&pio 7 0 GPIO_ACTIVE_HIGH>; // PH0 = GPIO224 (if connected) }; }; And compile it: sudo armbian-add-overlay /boot/overlay-user/bt_enable_full.dts Then enable it in /boot/armbianEnv.txt user_overlays=bt_enable_full See if there's an improvement on boot.

Here is the login prompt that failed: And about my SD Card, it is just a class 10 SanDisk Ultra card but does not say A1 anywhere. So next I tried the pre-built image for Cubieboard and it booted too! This is more stable than before, but as soon as I try to do downloads or file operations, I start seeing similar page state or mmc errors. I think this might be related to RAM frequencies as you mentioned. Is there a way I can change DRAM clock on a system after it boots? Adding to that, is there a way I can enable the display on this after it boots, or install drivers using an overlay? That would be great to test things out. I am trying to build again but it keeps failing at the same stage as last time, even after pulling the latest version. I think I should try either docker or a VM to build this, because it does not seem to be working on WSL. Thanks, Shivam
