Lockup

5 comments

Every once in a while, I hit the wrong configuration line, and smetimes I get a message something like "Unable to load ROM.. trying to load..."

The rest of the message is truncated.

I really would not mind this so much, but when it does that, I can't get back to the Pi or the Amiga without powering off/on. I have managed to get back a few times, by waiting a LONG time, then hitting aCR, but that only happend a few times.

After power off/on, it usually comes back, but then I can't boot properly. I don't recall the message I get. The only recourse at that time, I think, is to reflash an SD card, load up all the extra stuff, and start again.

Any way to get out of that lockup?

 

That brings up an additional question. What is the best way to back up my entire SD card? I tried making a new one using Win32DiskImager, but I ended up running out of room on the new card. Perhaps it would still work when this happens,. I haven't tried it yet.

 

Love Amibian! Takes me way back.

hey. best way to get out of this problem is wither deleting the configs that you dont use or assign a rom to them so they work. :)

backing up the sd card is best done with win32diskimager. problem is that not all sd cards are exactly the same size. you can also shrink the image in another linux system and then use dd to capture it.

OK, thanks, but here's the thing. I have discovered, through trial and error, that if I wait long enough before pulling the power, it will come back. Sometimes.

Other times, it seems as if I have to hit a Return and/or an F12, then wait a long time, and it will (again, sometimes), come back.

I am trying various ROMs, but it's pretty painful with all the waiting, and I really don't like to pull the power, as it sometimes clobbers the image.

 

The other thing, about shrinking the image... is there a way to find outthe size I would need to copy? I gather you mean I could use dd, with a "count = BLOCKS" option, but I don't know if there's a way to find out how much to copy without clobbering some of the good data. Any ideas on that?

 

I also find dd to be very slow. I suppose I could write a short program for Windows, that would truncate the image file, but I don't know if Win32DiskImager goes by information in the file, or just goes by its size. I'll try experimenting when my Amibian comes back.

About shrinking the image, you cant just count the blocks with dd. you first need to shrink it. win32diskimager copys the full sdcard, unused and unallocated space aswell. You can use a program like gparted for linux to shrink the image. then you can use dd and count the blocks, just make sure you take a few extra for buffer zone :) thera are some guides to do this that you can find with google. Doing this with wondows is something i have no knowledge about .. not a windows user you see ;)

Well, I figured out a better way to get out of the lockups I was getting. I just log in using SSH, and reboot. Works good. Now I won't be so reluctant to try different configs with different ROMs.

glad you found a way that works for you. :)

    Compiled notes about quick fixes and bugs in 1.5 beta (Syntax Error Party Edition): This is a beta version of Amibian 1.5. Work in progress... - No Pi 4. No Pi 3A+ No Pi 3B+...Yet... Works on Pi 3 and likely most earlier Editions: 512MB versions may cause problems. This beta version will not be update-able. The emulator however is. There are a few bugs on there, but no lethal ones 😉 Most annoying one is that USB flash drives don't work (mount) as is to copy files. - To fix: sudo nano /lib/systemd/system/systemd-udevd.service - Change MountFlags=slave to MountFlags=shared - Save and Reboot. Path of 1st USB Drive will likely be /media/usb0/, (not /mnt/Volume ID as in 1.4) Files will go in /home/Amibian/amiga-files/ (not /root/ like 1.4) - Seems to forget ROM File used in config. Have to re-attach every time you reload the emulator or a profile. - There may be an issue remembering exact paths of files (ROMs, Floppies, HDDs) (This turned out to be a corruption issue; after re-imaging it remembered settings) - Directories may fail to allow writing. recommend use sudo when launching files: i.e. > sudo mc, or > sudo chmod -R 777 [path of HDD files tree you want to be able to write to: +RWX] > sudo raspiconf etc etc... - Copies in mc seem to stall...very bad!! Not just in Amibian... Think this may be my hardware issue. SD card Corruption is common for me right now...both emu and hdf files. - Keyboard quirk with X and P. There was a setting fix to turn off bug ( forums / facebook) - Keyboard bug: the "p"= p2 and x = "x + CR" is another issue - [find forum /FB fix link] Good things: - I had some luck with RTG . >DBLPAL (640x512), 800x600, 720p, 1080p Noted Picasso96 has uaegfx awareness. (http://aminet.net) OS 3.9 does too; has device in devs/monitors - Still working on easy answers and process / explanation for implementing RTG. It has been quirky and I do not fully understand yet. - Both ClassicWB and AmigaSYS 4 (A1200, A4000, and Amiga Forever Editions) work , with web browsing. (FTP and other net protocols like FTP and IRC may have issues. Still to play with TCP stacks and look at my systems that work... I have 4 ways to emulate available. - Was able to get WiFI AND Bluetooth both working . (Internal WiFi, BT Mouse and Apple Wireless BT Keyboard this go around) no more yanking my Pi off the table! WiFi: (set country in raspiconf, edit SSID and key by typing wifi) (may not need sudo here) - before my devices staarted acting up it worked great!! Having write errors have new PSU on the way+ paying more attention to cooling. BT: https://www.raspberrypi.org/forums/viewtopic.php?t=138145 what i did was -similar- bluetooth capability installed in 1.5b but may need to be turned on, I also scanned for device IDs. sudo hciconfig / sudo hcitool scan <-- (all i did... here...) Other notes for later... in the [bluetooth]# type agent on followed by default-agent / To pair type pair xx:xx:xx:xx:xx:xx where xx:xx:xx:xx:xx:xx is your BD address of the device you want to pair / Next type trust xx:xx:xx:xx:xx:xx Resatarting my 1.5 image due to corruption. Thus these notes... want BT & USB.

    I'm trying to install amibian 1.4 on my raspberry pi 4B, it seems this is not compatible with eachother. Or am i doing something wrong?

    Having gotten a little frustrated with networking and reliability for the moment, I decided to look deeper into AmigaSYS4. I was able to download and install a custom Workbench with AmigaSYS4 in Amiga Forever 8 (AF 8) which i have had a bit of success with, getting on the internet with Amibian 1.4. I also had some luck getting High Resolution (800x600, VGA, 720p, 1080p etc.) under Amibian 1.5 beta and FS-UAE on Raspberry Pi 4. I have since noticed while installing Amiga OS 3.9 on AF that it creates a monitor for UAEGFX and includes a Picasso96 install which is also UAE Aware. I will be looking into that deeper soon... So today I have been playing with AmigaSYS (https://www.amigasys.net/) designed to get you a highly functional 1200 or 4000 quickly. I am about to start trying it on Amibian Beta. For someone looking for an EASY way to set up and play with workbench 3 that has been customized and enhanced, AmigaSYS seems to be the most comfortable and simple winner. It looks like it was produced around the time of Amiga Forever 5 & 6. Not only does it take all the work out of having to learn a lot about Workbench to install and make it , but it also plays music while installing and references other websites to visit, and produces some nice splash screens.. I did a screen capture during install. It gets 10/10 for easy. Too early to tell but i am betting on a high score for usability as well. Plan on this for "I want an easy way to experience workbench without all the work to set it up." or a very easy and comprehensive "Quick Start" A1200 / A4000. Was able to get on the Web with Amibian 1.4 it but so far has had SSL deficiency. Will need to install a current AmiSSL on it for better web usability if internet surfing is intended. Other Alternatives: ClassicWB. http://classicwb.abime.net/ More configurations, options, confusion during install (no screenshots of "what does this option do - or look like?), but good to set up and better as a gaming system or more complex daily use Amiga Workbench system. Better if you are willing to learn and read more, and do some configuring and building of your environment. Overall: Lots more options, more confusing, and no frills during install. Nice outcome though. May be preferable for gamers due to scripting /system for adding multiple WHDLoads and multiple library front ends. Both are a substantial upgrade from a standard workbench install. Both projects demonstrate a lot of work to save you a lot of time figuring things out. They will both be instrumental in preserving the Amiga legacy by getting new people started and old folks up and running faster (Like me - but i will dig and learn & hack too - I have done all along with A1200, A600, A500, and CDTVs.). Which Download? If you download the beginner pack ( 40MB expands to 100MB hard disk file or .hdf ) you get a .hdf and instructions. You boot the hardfile and insert 1-2 WB 3 floppies (AF = Amiga Forever produced Amiga Disk File or .adf), choose Magic Workbench Icons or New Icons (more resource hungry) and a couple options and you are on the way. If you download the advanced pack you get an archive with the raw files to extract on an existing Amiga Filesystem. (have not used yet and presume you manually copy the files from your Workbench disk and presume it may be customized less...leaving you to customize according to your own preferences) The ISO (155MB) appears to have has everything. Files + HDF + instructions. Screen Shots: AmigaSYS with Magic Workbench icons 64 colors w/ DBLPAL video mode AmigaSYS with New Icons 64 colors w/ PAL video mode 640 x 256 AmigaSYS with New Icons 64 colors w/ DBLPAL video mode 640 x 512 (Interlaced/Fixed - use "Double" option under video settings in emulator) Notice selection menu cuts off 1/2 way down, this is the difference between non and interlaced resolutions. Classic Workbench: Re-Gen appearance (Also has Classic and Retro Gaming options) (The -Other- Amiga Preinstalled Environment) I will play with these tonight under Amibian 1.5b (Maybe 1.4 too) and post my findings... A4000 8M base mem, 2 M Chip, 16 M ZIII, 64M Video RAM, ClassicWB UAE P96 v28 fresh load. Set screen at 1920 x 1080p. Amibian 1.5 Beta AmigaMax
