Re: RPI3 USB Hardware Bug?

Er what? The Raspberry Pi kernel has been open source since the release of the pi one so I'm not quite sure why you think it's closed. You may have missed it in the post above but in my tests dolphin and Kwrite both work perfectly well on the latest model pis with the latest stretch. It is? I read ...

Re: RPI3 USB Hardware Bug?

We've sold millions of 2's and 3's. If there was a big problem with the USB hardware (underlying SoC USB is the same on ALL models of Pi), I think we would have noticed by now. The fact there is ONLY a problem with this particular stick and this particular driver indicates to me that its that stick...

Re: RPI3 USB Hardware Bug?

We do not guarantee any particular third party USB device will work, mainly because we don't design them or write the drivers for them so will probably not be able to fix them anyway. We have plenty of our own issues to deal with so why should we fix other people defective software before fixing ou...

Just tried dolphin and kwrite on my 3B+ running latest Raspbian plus kernel 4.14.50, both worked fine.
4.14 from April. All images are missing if you run it as root. (both required in root mode). I made photos but already deleted it.
With lastest wheezy it works.

Re: RPI3 USB Hardware Bug?

If we didn't care we wouldn't have spent the last week debugging odd ethernet issues on the Pi3b+, or investigating a Wifi bug, or any other of the myriad things we do every day to make the product work better. In fact, I think you would be hard pressed to find a more dedicated team. Just because y...

You mention upgrading from a 3.x kernel. Have you tried a fresh install of the latest Raspbian?
Its very difficult to get a new image run all Software that is on the old card.
Stretch is buggy and cant run dolphin&kwrite.
But i prepared a bit a wheezy Version but no time to complete.

Re: RPI3 USB Hardware Bug?

That has nothing to do with specific Raspberry Pi builds. I am running a fully updated Ubuntu PC and the dates on the files are similar. There are no newer versions in the "stable" (Stretch) release. The ones provided do work with the current kernels. The crc of the updated/upgraded card has old Fi...

There is no password for root by default. Your system works fine. Just type: sudo su Its not fine if "Root Terminal" can startet&used in wheezy but doesnt work in jessi/stretch. If it ask a password, for a user that has no password set, its a bug. I know about sudo su. If i tell you that you have t...

Re: RPI3 USB Hardware Bug?

You seem to think we port (ie change for Pi) a lot of these drivers. We don't. The huge majority of code running on the Pi is upstream code, simply recompiled. Also worth noting that if all these drivers were bug free, why do they continually get bug fixes released for them? You only need to subscr...

Re: RPI3 USB Hardware Bug?

Sorry, I do not understand most of this post. As far as I can tell it doesn't really give any idea as to where the bug might even be, although I am presuming it's in the driver for the stick somewhere, which is NOT OUR CODE. We cannot generally provide support drivers for devices that are not produ...

Very bad support.
Still there the Bug with newest kernel 4.14.44-v7+.
Is it possible to use 3.12.22 wireless modules? they are not accepted if i simply copy them over but maybe there exists some trick to use it?

Re: gcc xprintf nan bug librtlsdr

You did say "I have a modified rtl_power version, moving around some global variables into functions" so maybe it is your fault ? But if you still think it's a bug then you need to raise a bug on the librtlsdr github site, they are the people that you should be talking to. I used the original rtl_p...

Or it means that there some undefined behavior in your program that just happens, by pure luck, to work on an x86 platform :) Its not my own program, its librtlsdr and its example programs.

See "man log10" and "man 3 log" that it refers to.
okay, i believe that.
Numbers on x86 that goes into log() are all positive.
Means gcc->arm trash the source at another point.

In C local variables are allocated from the stack. If local variables are not initialised, they will contain what ever data was left over from previous use of the stack. ..
