I would like to add a reset button to a dm900 similar to the reset button of a personal computer. It should just restart the box directly. You will probably tell me "Why, there is already a on/off switch?" and I will tell you, that I would like to reset the box without shutting the power off. Why? Because I have an SSD inside. As you might know, the SSD needs power to reorganize the written blocks internally, to avoid that one block is written too many times, because there is a life limit of about 1000 writes per block. The controller chip inside the SSD does this automatically. But if you switch off the power it can lead to problems. I have now lost two SSDs in the last 2 years. It happened usually shortly after a freeze of the player software gstreamer in the middle of a movie. I tried to connect by samba intranet and kill the process but no connection was possible. Means even the Linux on the box was probably frozen or the memory was so full that nothing was going anmore. I have the suspicion that maybe my switching off the power was the problem. Or that the gstreamer previously repeatedly wrote to the same block which would explain why the directory was broken after the restart. In any case, I would like to try and reset the box with a hardware button from now on, to see whether this fixes the SSD loss. Two losses are now more than enough for me. So the question to the hardware savvy people: Do you know whether there is either a reset pin (similar to a PC motherboard) or just which capacitor or data line I need to solder the wire to. I have ample experience with hardware with PCs. In a PC I would expect it to be found on the ECC chip but I haven't found a schematic of the dm900 up to now. Any info would be very appreciated. Thanks to all.

Hello,

I personally think that your logic should be "reversed", in fact the problem of the freeze and block is not creating the SSD problem (corruption or breaking), it's the opposite... the SDD failed, AND the Gstreamer/software crashed as well as freezed the box.

You can always get in touch with Johnny, about the logic of the reset, as he has a clear understanding of the schematics of the DM9x0 boxes.

The SSD problem did not happen at the same time. I experienced freezes several times over the year. Usually during watching of videos from H265 files. Sometimes also when subtitles (to a video of any format) are activated, be it the ones embedded inside or be it from external srt files (I am the author of a subtitle downloading software 'Atlas Subtitler', so I activate srt files a lot). The worst crashes are usually the H265 format incompatibilites. Sometimes I still had Samba access and could issue a "systemctl stop enigma2" command and I waited for minutes. Sometimes it worked, sometimes if froze and even 30 minutes later still frozen. Then I was forced to brutally turn the switch off and on. The SSD problems happend months later. The SSD started to show reduced content of folders or even empty folders. First only one then more. The error "Read-only file system" was displayed when I tried to copy back the backup. I sent the Silicon Power A55 2TB back to Silicon Power for repair. They sent me a totally new replacement. My suspicion was maybe some NAND blocks were totally destroyed by too many writes. But, the SSD controller should simply reallocate to other blocks. So I don't really understand why the SSD was broken. That was the second one. The first one was a fake Samsung 870 EVO. I always thought is was a real one but when I looked inside it was a fake. Interestingly the fake looked very similar to the Silicon Power. Maybe the same factory is producing for Silicon Power and for the scammers. Maybe the loss of both SSDs is exactly because the same chinese s**t NANDs are inside. But I use another Silicon Power in my PC and it works flawlessly since years.

All this is why I want to try a reset hardware button instead of a power off and on. I just need to know where to solder it. Actually, it would have been better for the Dreambox design if the original button would do a cold start after maybe 20 seconds pressing or so. Just like Notebooks usually do it.

I believe the best is really Johnny who can tell you what to do exactly,

Personally I lost a 2 Tb Samsung SSD on a Thinkpad Lenovo x220 laptop, dead, not bootable (probably the first sectors destroyed [there is a way to get it replaced as its a 150 USD SSD ?], and this was using it with large files (VM with Linux) to compile images, but this also happens on some other Samsung EVO as well where some files are not more accessible (corrupted), also from these large VM files... perhaps some related way to work ? So I can clone the HDD, and let it "fail" where there is bad sectors, to save it, but I lost like that some VM, hopefully I save the files into a tar.gz so I can regenerate the compile tree on a VM from a new OS/VM install.

P.S.: Can you email us at toysofts@gmail.com the avatar you use on your profile, so I can add it (and find why it's not showing up on your posts/profile). I just did a fix on the configuration, perhaps you can now upload it and have it working/showing up.
