Re: Commercial Use of the Pi

Well, the Zero wasn't really designed as you say, it was designed, really, to see how cheap it could be made. In fact the Zero isn't that great for IoT applications for one big reason - power consumption is too high. It cannot be battery powered for any length of time so needs to be hard wired to a...

Re: Commercial Use of the Pi

I lost my long writing when the page asked me to login again ... grrrr ... To be expedite. The Zero was not designed as a desktop but as an embedded machine, more similar to the CM than to the RPI3 or 2 series of computers. In fact, the Zero it is like a CM with ports, making it perfect for projects...

Re: Commercial Use of the Pi

I have been thinking ... how to reduce price, how to reduce price (to increase possibilities) ... First came to my mind, why not to sell the memory separated from the device? This way you can put whatever quantity you need on it. But after a quick search, the cheapest memory modules are huge (in siz...

Re: Commercial Use of the Pi

Whatever happens with the Raspberry Zero or Zero W about expectation and availability, they already forced the market to react, and it is very important that somebody takes so important step (thanks Foundation). $5 it is a hard goal for anybody ... the Raspberry is the leader, but we have also the O...

Re: Commercial Use of the Pi

There is no problem when somebody creates a device with a distribution restriction. However, there is a real issue when an expectation that can't be fullfilled is created. When the Zero device appeared at $5, the Raspberry Pi was already a "best seller". Then the message was very clear: this is not ...

Re: USB boot now working on Pi3

I have another open question, that I think it is extremely important. To the people that already have the booting process working, did you test if the Raspberry can reboot reliably after the first boot? And a secondary related question. How many times the reboot process, after the first boot took pl...

Re: USB boot now working on Pi3

Yes, ... program_usb_boot_mode=1 This is a RPI3 I have been using to try this booting procedure since several weeks ago. So that was already burned on it. If it is safe to do it in another RPI3, I could try with another machine just in case "something" happened with the machine I am using right now ...

Re: USB boot now working on Pi3

My last test for today (I god a headache doing this). I made a full clean install following the instructions on the PiDrive device with all the latest software versions. It doesn't boot without the SD card, no way. When I add the empty TIMEOUT file, it boots, but only the first time after I provide ...

Re: USB boot now working on Pi3

But they don't boot at al, not even once, without the SD card in place, neither with the SD with only the bin file there (needs all the...

Re: USB boot now working on Pi3

One question to the forum members. Did somebody already test this with the WD Pi Drives? They are supposedly designed to work well with the RPI machines. What I see is that the RPI didn't born with this functionality ready at hand, and could be possible that, although in some cases it will work, the...

Re: USB boot now working on Pi3

Interesting finding, Chas123. Let me see, you used a 5A power adaptor (twice the recommended capacity for the RPI). Although I don't have so powerful adaptor per port at hand, I made another test with 12A power adaptor (this provides 2A on each of its 6 USB ports). The same result as before. Then, I...

About weak power sources. I am using a 2.5A dedicated Canakit adaptor (I have around 7 of them and other power options and all my RPI machines work according with their specifications). When booting from the SSD disk on the RPI3 modified to boot from USB, I have mixed results. When booting from the ...

Re: USB boot now working on Pi3

I noticed a new version in the next branch (Aug 30th), so I made a new test today.

Memory issue : fixed.

5 boots ... zero problem
1 boot ... colored frozen screen
1 boot ... zero problem

Is there something in the RPI3 (the machine itself) that becomes unstable after some continuous reboots?

Re: USB boot now working on Pi3

Good eye ... as I was checking the booting process I didn't notice that the kernel was reporting only 128M RAM. Reboot ... and it still shows 128M RAM. Then made a rpi-update without the "next" branch, then rsync (for not to mix different versions) and booting from the SD card with my root on the US...

Re: USB boot now working on Pi3

Hi CaptManiac. There is something you could try ... although I don't know if this will break some dependency. 1) Check what is your Kernel version (uname -a). If it is 4.4.16 or greater, then your /boot partition was updated with the apt-get upgrade command and probably you lost the special bootcode...

Re: USB boot now working on Pi3

I have been doing all sort of tests today. First, I used a newer Jessie Little with kernel 4.4.11 ... that was upgraded to 4.4.15 with the rpi-update. First, I had the same behaviour with all the combinations made before. Then, I made a copy from the SSD disk into a Lexar 32 GB USB Memory stick. For...

Re: USB boot now working on Pi3

No no no ... 16GB SD and 128GB SSD (with 100MB boot partition). Let me do something, because I separated that RPI3 for this case. I will clean everything and to make a basic minimal installation, even re-partition the SSD (maybe to give 98MB for the partition table to be different), and a root parti...

Not only that.

For the test I took a brand new SD card and copied there the bin file, recently downloaded from the next branch. Could be possible that I am using the wrong file?

mm ... I think it is not my case, because the big partition it is not the boot but the root one, and it has an ext4 file system. But it is good to know about that. This is the information about how my disk has been partitioned, following the original instructions to test this native booting process....

Re: USB boot now working on Pi3

I still need to make the new tests, but about my last post: to boot from SD always work. to boot from SSD only (no SD in the RPI3 slot), fails the most of the times. In both cases, ROOT is on the SSD. To be 100% sure I am not making mistakes, I performed an rsync between the boot partition on the SD...
