I've upgraded to 5.20 from 5.17 and I've had to modify my /boot/bin/micro.bin to activate the VGA output. After Upgraded the board didn't reactivate the VGA, and I've to do it manually. Maybe some warning in the changelog will be an help to those have to do such modifications. The upgrade process copied the bin dir to bin.old. I have to apply "sudo apt-get upgrade" twice as the first run complain about come conflicting files and abort the upgrade, the second run did the job. I'm running legacy debian Jessie image and upgraded from 5.17 to 5.20. Now it seem to work well.

Thanks, i will try this value asap. Regards

the entry in /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq (maybe the path is wrong, I haven't the machine and I'm going by memory) is readable only by root so it is not usable to a normal user to display the current frequency of the processor, There is a way to change this behaviour? My distribution is for Olimex-A20-Micro with legacy kernel 5.14 if i don't go wrong. TIA and regards

mount $LOOP"p1" /mnt give me this error mount: il device speciale /dev/loop0p1 non esiste roughly translated "mount: special device /dev/loop0p1 not exist" I'm using Lnux Mint 17.3 (Ubuntu 14.04 based) Partially Solved: sudo kpartx -av image.raw sudo mount /dev/mapper/loop0p1 /mnt/test/ .... do the modifications sudo umount /mnt/test 1) apart for modifying the script.bin in the boot.cmd that i suppose is the equivalent of the grub.cfg for uboot i see: setenv bootargs "console=ttyS0,115200 console=tty1 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 cgroup_enable=memory swapaccount=1 hdmi.audio=EDID:0 disp.screen0_output_mode=1920x1080p60 panic=10 consoleblank=0 enforcing=0 loglevel=${verbosity}" This option disp.screen0_output_mode=1920x1080p60 Has to be modified to use the VGA at 800x600p60 or 1024x768p60 Now is working, I found on this site the relevant information to modify, and recompile the boot.cmd, that I have missed to see the first time. I can guess that 800x600p60 is resolution (p)frequency but for the mode VGA or HDMI ? Where could I learn some more on the boot process? A little question remain, when the modifications made in micro.bin and in boot.scr are overwritten and are needed to be applied again? This question was modified in the Armbian environment during the apt-get upgrade phase. :-D Updating to 5.16 from the 5.14 image that I've Downloaded and modified, I have noted this: The old bin was renamed bin.old and mantained in place, so I've: 1) renamed micro.bin in /boot/bin 2) copied my /boot/bin.old/micro.bin in /boot/bin as is (maybe this is not too safe if something change) 2) "recompiled" my boot.cmd (that from the timestanp seems unchanged) in boot.scr (just in case) And rebooted, all working. I have seen how to assign the static ip to my wlan adapter (The wicd applet in the stock XFCE have these settings) Installed Mate-Terminal, removed icedove and installed pyserial and python-tk to make my CNC working (I forgot to say that the Olimex Board is the controller of an eShapeoko CNC) Now I have some little problems. 1) I need an applet that show the state of caps lock and block num on the panel, as my keyboard has no leds on it. 2) how to suppress the verbose startup and put maybe a static image till the desktop is on Hope maybe here i will find some solution. TIA and Best Regards Carlo

I have found, installed and compiled the tools on http://linux-sunxi.org/Sunxi-tools I have mounted the image on /mnt/test as stated in some other place of this site and "decoded" the script.bin file in /mnt/test/boot The image is Armbian_5.14_Micro_Debian_jessie_3.4.112_desktop.raw But the decoded fex file says [disp_init] disp_init_enable = 1 disp_mode = 0 screen0_output_type = 1 screen0_output_mode = 5 screen1_output_type = 1 screen1_output_mode = 5 But screen0_output_type = 1 is accoding to the Fex-guide on the sunxi site the LCD display and not the HDMI as I argued from the documentation. Apart from modifying the relevant VGA voices, I think screen0_output_type = 4 screen0_output_mode = 5 or 4 will perform well on my hardware The remaining problem is: how to re-transform the modified tree in /mnt/test that contain the new script.bin in a .raw image that has to be written on the SD card? TIA and Regards Carlo

Hello. There is a method to activate the VGA output in the SD image? I explain better, I want to replace the stock Debian Image that came with the Olimex Board, but the system is on a distant location where there is no computer, I need to swap the SD card and have the system booting and usign the console of the machine to perform all the remaining operation. I need to have the SD Card image that boot with VGA output, the rest of the operation coulbe done with the machine, (I nedd to configure the wifi and connet to the router and then in internet) I have read a topic that said that i nedd to modify the fex file, but this is feasible with my computer running Linux mint (Ubuntu 14.04)? TIA and Regards Carlo
