I've been using systemd-networkd with espressobin for long. The trouble with starting i-net i-faces on boot exists from the origin. I get used adding the following to my # cat /etc/rc.local ## if necessary to activate wan i-face /sbin/ip link set dev wan up Another solution to explore : ## Jul 13 22:16:50 2018 action merged with systemd-networkd.service ## ExecStartPre=/sbin/ip link set wan down | up

This is just to report, that Image file Armbian_23.11.1_Espressobin_bookworm_current_5.15.139.img.xz is not mounting. Downloaded from https://armbian.site-meganet.com/dl/espressobin/archive/Armbian_23.11.1_Espressobin_bookworm_current_5.15.139.img.xz Mounting from loop or from USB gives the same error: # mount /dev/loop0p1 /mnt/img/ mount: /mnt/img: wrong fs type, bad option, bad superblock on /dev/loop0p1, missing codepage or helper program, or other error Is there other working image?

kernel 5.10.60 is the last version I've managed running v7 @ 1200 MHz with cpu frequency stepping. Thus, if you want the latest kernel, I fear you would need to downgrade your u-boot to 1000 MHz. I don't believe there were recent development debugging this issue, although there is a need for.

I have a working BPi M1 with [ 0.000000] Linux version 5.15.25-sunxi (root@d72d155687c7) (arm-linux-gnueabihf-gcc (GNU Toolchain for the A-profile Architecture 8.3-2019.03 (arm-rel-8.36)) 8.3.0, GNU ld (GNU Toolchain for the A-profile Architecture 8.3-2019.03 (arm-rel-8.36)) 2.32.0.20190321) #22.02.1 SMP Sun Feb 27 09:23:25 UTC 2022 Due to inconvenient USB placements, I thought using OTG micro USB (the one right next to the SD slot), but it doesn't seem to be operational. I bought a Micro USB Male To Female OTG Adapter Cable, but the attached devices are not detected neither connected to OTG port, nor to the normal power-in micro USB connector (located between SATA and SATA-pwr). I attached the same Micro USB Male To Female OTG Adapter Cable to my Android phone and devices are recognized and activated. For example an external keyboard worked with the phone. What is the current USB OTG support status and what is necessary to debug its functionality? I quick look at kernel configuration: root@bananapi:~# zcat /proc/config | grep OTG CONFIG_USB_OTG=y # CONFIG_USB_OTG_PRODUCTLIST is not set # CONFIG_USB_OTG_DISABLE_EXTERNAL_HUB is not set # CONFIG_USB_OTG_FSM is not set CONFIG_USB_FOTG210_HCD=m # CONFIG_USB_FOTG210_UDC is not set root@bananapi:~# zcat /proc/config | grep CONFIG_USB_DWC CONFIG_USB_DWC3=y # CONFIG_USB_DWC3_HOST is not set # CONFIG_USB_DWC3_GADGET is not set CONFIG_USB_DWC3_DUAL_ROLE=y CONFIG_USB_DWC3_OF_SIMPLE=m CONFIG_USB_DWC2=y # CONFIG_USB_DWC2_HOST is not set # CONFIG_USB_DWC2_PERIPHERAL is not set CONFIG_USB_DWC2_DUAL_ROLE=y # CONFIG_USB_DWC2_DEBUG is not set # CONFIG_USB_DWC2_TRACK_MISSED_SOFS is not set What is necessary to make OTG working?

Sadly, there is nobody. 1.2 GHz variant of A3720 will remain flawed.

Hello Pali, Thank you again for pointing out this flaw. I recall your alert earlier this year : https://forum.armbian.com/topic/19564-making-espressobin-v7-work-in-2022/page/2/# Beware, 1.2 GHz CPU is broken and Marvell refused to fix it. Hence kernel maintainers decided to delete/deactive 1.2 GHz mode. https://lore.kernel.org/linux-pm/20210809040224.j2rvopmmqda3utc5@vireshk-i7/ So rather stick with 1 GHz mode. Now kernel upgrade reminded this bug again. It remains yet unclear to me, why the 5.10.60-mvebu64 kernel works on 1.2 GHz variant of A3720 SOC and apparently does frequency scaling, while the next 5.15 tree does not. If init sequence related to CPU voltage configuration satisfy the 5.10 tree, why is it no more valid for 5.15? I have another ancillary issue with uboot implementation. When I followed your u-boot build guidance in February 2022, I didn't implement U-Boot distroboot feature by that time as Armbian distribution was not yet ready. Thus I haven't set default environment in u-boot so far. Armbian is currently passed from boot_targets=usb sata mmc1 mmc0 bootcmd=for target in ${boot_targets}; do run bootcmd_${target}; done instead if distroboot implementation : bootcmd=run distro_bootcmd What are implications of not setting default environment (=> env default -a) in u-boot with "distroboot Armbian"?

I used Igor's advice for another issue : Workaround: armbian-config -> system -> Other -> Switch to other kernels , pick previous, freeze, wait | |linux-image-current-mvebu64=22.08.2 5.15.69-mvebu64 | | | |linux-image-current-mvebu64=22.05.3 5.15.48-mvebu64 | | | |linux-image-current-mvebu64=22.05.1 5.15.35-mvebu64 | | | |linux-image-current-mvebu64=21.08.1 5.10.60-mvebu64 | | <<-- CPU scaling is not broken I progressively downgraded to kernels 5.15.69, than to 5.15.48 and 5.15.35. None of them allowed to fix CPU scaling. This is rather strange, as I run another espressobin, which doesn't loose CPU scaling with kernel 5.15.48-mvebu64. This second espressobin is version 5 and u-boot running at 1000 MHz. This could give a clue to fix broken CPU scaling in kernel 5.15.xx.
