OpenDingux release 2019.06.01

Another month, another update.

Changelog

  • Added USB mass storage mode (MTP). Finally, you can transfer your apps other files without any specific software! Use the 'USB Mode' app in the settings tab to revert to the Ethernet-over-USB mode that was the default in the previous versions of the firmware.
  • Added 20 MiB of in-RAM compressed swap (zram). This will permits some RAM-hungry apps to start, although with a performance hit vs. those who don't require swap.
  • Switched from mdev to udev, which fixes some issues, like the automounting of SD cards.
  • The brightness setting is now preserved across reboots.
  • And most importantly, the cow is back. Those who used to develop for OpenDingux on other devices will understand.

Download links

The update OPK can be downloaded here: OpenDingux update OPK.
Be careful that you must have at least 25 MiB of internal storage before running the update.

Enjoy!

    Nice! Thanks! With this update I can now play ridge racer on pcsx4all-20190524. Is it okay to remove ‘rootfs.squashfs.bak’ if everything works as supposed? What’s the ‘cow is back’ meaning and should the new developers care on it? Do I need any toolchain updates (since ‘2019.04.30’ post) if I plan to compile something? Is it possible to cross-compile with msys for windows?

      While you can remove the rootfs.squashfs.bak file, it’s protected so you can only remove it by connecting through telnet or SSH. And even though I’d advise against it.

      When you will see ‘the cow’ you will understand.

      You don’t need a new toolchain. Use the 2019.04.30 one.

      About msys / windows, I never did that, so you’re on your own.

    Hi and thanks for your efforts.

    But how do I like the emualtor that was copied to my sdcard? I couldn’t find any options for that or did I miss something?

      Make sure the files are in OPK format, and are for the Retromini. Then just copy them in the “Apps” folder, and they should automatically appear in the menu.

    Heya, i cant get my retromini recognized. I’ve tried to install the drivers on win10, win7. I’ve tried to use xubuntu and ubuntu too, but i always get “cant find ingenic device” every time i start the patcher. How can i fix that? N.B. When i connect the retromini, i always connect it turned off. Then i turn it on while pressing A or B button, for the USB Boot mode. It is normal that the screen is total black?

      It’s normal that the screen is black, yes. On Ubuntu don’t forget to run the script with “sudo”.

    I just flashed my retromini with the version of 2019.05.17 but it appears that I have 170 / 192MiB and now I want to update to this new version as I can make space in memory. :(

    I attempted to upgrade from 2019.05.17 unsuccessfully. I had ~110 MiB of NAND free at the time yet I still got the “Out of memory” error. Now it seems to be stuck in a weird state when I attempt to boot: “—[ end Kernel panic - not syncing: Attempted to kill init! exit code=0x0000ff00 ]— . Then about 50 seconds later I get “random: crng init done”, then no further messages (waited about 5 minutes). It does that every time I boot now.

    I attempted to reflash the 2019.05.17 build, but I now get “Unable to find Ingenic device” , “Detecting OpenDingux…” , “Found Ingenic JZ4750 based device”, (no, that’s not a typo), then it writes a bunch of bytes and “Operation complete” but I still get the same behavior on next boot. lsusb shows the device in the filesystem “Bus 003 Device 019: ID 601a:4750 Ingenic Semiconductor Ltd. “

    Any thoughts on what to do now? The device was working great for about two days under 05.17 before the failed upgrade.

      You can boot the backup kernel by pressing START when powering on, and the backup root file system by pressing R. Then it should boot to a working state and you can attempt the update again.

      If you still have to reflash… make sure you run the script with “sudo”, and that the Retromini is in USB boot mode (press A when powering ON). If it still doesn’t work, try with a different USB cable.

    Ok great, thanks. I notice you have the info about START and R at the end of the upgrade OPK process, perhaps that splash could be moved to the front of the process before any bytes are written? That info would have probably enabled me to troubleshoot this on my own.

    I was still unable to upgrade to 2019.06.01, and I couldn’t get the flasher (v30.sh) to work either in that state. However, the 2017.05.17 upgrade OPK worked nicely, and I now have a nice working device again.

    Anyways, thanks for all the porting work - You have rescued this very nice hardware from the bad software it shipped with!

    FYI, I am not sure if the Dingoonity forums are accepting new registrations.

    I attempted to sign up several days ago, yet the status is still ‘pending’. A quick DDG seems to indicate others with similar issues in 2018 and 2019. I sent an email to Max just now to ask about it.

    So, open question for anyone reading this - Have you managed to register an account on Dingoonity in the last 0-12 months?

      In the home folder, inside .gmenu2x/skins/Default/wallpapers/ (create it if it doesn’t exist). The wallpapers must be 320x240 resolution and in PNG format.

      It stops because it is fully charged. The battery level in the menu isn’t well calibrated, that’s why it only shows half-full.

      Either your unit or your battery is defective, I get about 5 hours on the default 1020 mAh battery.

      How is my unit or my battery defective? my Retromini bought it in good condition but I changed the battery to another of a Nokia cell phone … I am thinking of buying a battery of more than 3000 mAh so that at least it lasts longer.

      The battery report widget isn’t well calibrated, it’s possible that it looks flat after one hour. But the battery should last much longer than that.

    Hi Vapor, (or others reading this)

    I can ssh to the device from any of my gnu/linux computers, but it seems very picky about which computers I can flash from. I cannot flash it from any port on my main laptop, it shows up in lsusb but I get the same “unable to detect ingenic device” message you are reporting.

    It works from my GPD Win 1 running Manjaro, so I use that to flash the device.

    Hello, thank you very much for your work, it is spectacular, but …

    My problem is that once flashed opendingux, I do not know how to access the internal memory, I have copied the update to the micro sd, the last update .opk, but It does not detect it, nor do the emulators to install from the micro sd, and I don’t know how to access the internal memory, I have windows 10, and the drivers are working, but I cannot access the internal memory.

    How can I access the internal memory from windows 10?

    Thanks again and regards

      The OPK update must be in the “apps” folder at the root of the SD card. If you don’t have an “apps” folder, just create one and put the OPKs inside.

      Then once you updated to the latest firmware it should be easier to access the internal memory, just plug-and-play on your PC.

    First of all thank you very much for the great work you are doing, I recognize that it should be difficult to spend time on a project like this. I had a doubt, I have the version of the machine with hynix memory, as I could read that version only works with the latest firmware, but I have heard that the gameboy advance emulator does not work with this version.

    Do I have to wait until you get an update to fix it or is there an easy solution for that problem?

    The truth is that the gaming experience with the original Chinese firmware is quite bad.

    Regards.
