![]() ![]() It's probably for the better that you went with a very user-friendly tool like Balena Etcher, you are doing some wonky things here. Guessing I need to use the serial cable and fix something in BIOS. Unfortuantly I am unable to get a CC15 image working on the same SD card as I had 17 and 19 on. I found this forum post that idicates CC15 should work. Instead I used Īt this point I have downloaded the ROM file and also figured out that I can just copy the file to the APU2's /root/ folder with WINSCP.įlashrom would fail indicating errors regarding /dev/memĬritical error: open(/dev/mem): No such file or directory and more The site with the ROM file uses SSL and there are missing files for wget that could not be found. First, one needs to load packages wget and flashrom (there are 4 flashrom packages, I just used the first) but /dev/mem's not there. Today I found your post on the /dev/mem and tried 19.07. I assumed it was an image problem, but I found links and this on the IPFire site that indicates that it's a serial cable fix. Spent a good chunk of time trying to get IPFire to boot on the device. I use it all the time, it ever occurred tome to try this. This yielded a Not a Directory error IIRC. I did all my work yesterday on the only PC I own with an SD card, my work laptop, booted to Ubuntu 20.įWIW: sudo dd status=progress bs=8M if=/dev/sdc1/openwrt-19.07.8-x86-64-combined-squashfs.img of=/dev/mmcblk0p1 More modern industrial boards lack BIOS boot, and Intel has been discouraging OEMs to include the legacy bios boot functionality for a while ĪPUs have BIOS boot so the "efi" image does not This has been a comedy of errors. No, the efi image is for devices that have UEFI boot only (or you want to boot them in UEFI mode for other reasons, like in a VM with PCIe passthrough). Is the combined efi for the x86/64 BIOS board's? Is the equivalent 21.02.0 file to the 19.07.8 version suggested in the wiki? To change this option you can only use serial port, because that's the only way to see BIOS interface Newer BIOS has an option to enable "Sdcard 3.0" which isĮnable SD controller in 3.0 mode to allow achieving full speeds with UHS-I SD cards Or rufus (which is able to make Windows installers as well) Īfaik older BIOS versions had issues with booting from some cards. But that's what gets the most press for Raspberry images for some reason.įrom windows I would have used win32 disk imager I think it's ridicolous to use a 120Mb Electron application (it is a web application running on its own bundled Chrome browser instance) like Balena Etcher to write a file to an external drive. No need to muck around with dd if you are just writing the whole file. You can just use cat (silent like dd) or pv (shows completion bar and writing speed). You can also install the OPNSense image and do the steps as said in the link of the bios update guide from techlagerĪfter struggling to DD an image for over an hour I found Etcher, Bada Bing, Bada Boom! up and running with 19.07.08. Tips for getting cheap used x86-based firewall with full Gbit NAT (a PC Engines APU) if you are in the US - #16 by bobafetthotmail Yes, flash an OpenWrt x86_64 image from release 19.xx or older (in newer releases /dev/mem is not accessible anymore and flashrom fails), connect with ssh and you can do what I said in the post above. Is there any way to update the bios from one of the images you mentioned without serial access? If you are worried about getting locked out just buy that.ĮDIT: technically yes there is UART pins you can use with the "usb serial adapter" you use with routers but to enable them you must change default BIOS settings, and this can only be done through serial port. ![]() I'd like to point out that a USB-RS-232 adapter is like 10$ and a null modem adapter is another 5$ at most. Is there any non-RS232 serial, pin serial access like with the cheapo USB to serial adapters?Īfaik no. ![]()
