Re: B+ and max_usb_current

Thanks for the explanation.

I have tried a number of different PSUs as well as leads and OS so I'm still thinking it's hardware but I have no idea at all how it might affect booting it in this way.

I have not been able to find anything similar in extensive searches over the last couple of weeks.

Re: B+ and max_usb_current

Both those suppositions are easily put to the test. Power up the RPi for several seconds to let the capacitor charge. Then momentarily short and release the two 'RUN' contacts adjacent to the ACT LED. Just tried that but not sure what I should be expecting. With no power parameter set the B+ reboot...

Re: B+ and max_usb_current

I don't intend to bypass the micro USB at all and hope only to be able to use a single HD with a separate power input directly to the drive, not via the RPi - as I have set up with the B at present. (The reference to 'another one' earlier is to another B that also has a HD attached, also containing ...

Re: raspberry pi B+ rpi_installer_08-19-12.zip

No doubt, but once installed the first thing to do is fully update which will surely bring in a new kernel etc? Edit: As far as I have tried so far the modified installer will still allow an install to USB stick or HD as well as SD but will not name the suggested partitions for you as did the origin...

Re: raspberry pi B+ rpi_installer_08-19-12.zip

It still works if bootcode.bin and start.elf are replaced with (much) more recent versions

Re: B+ and max_usb_current

Not a good sign. Is this with one or 2 HDDs attached? If 2 then unplug one of them. As already said, this is with no HDs attached - nothing but keyboard and LAN The setting is only intended to be used with a power supply of sufficient capacity. If 1.2A is selected, a high-current load is connected ...

Re: B+ and max_usb_current

Yes, each of the several raspbian installs I have done has been brought fully up to date as soon as installed - and I did another aptitude and rpi update again this afternoon before my latest attempts. I mentioned in my first post that I have also tried safe_mode_gpio=4. I have them both in config.t...

Re: B+ and max_usb_current

Yes, the B is attached to a disk, as is another one, but neither are through a hub. HD is attached directly to RPi USB port, OS is on HD, SD is only used for boot. These two HDs are USB 2 devices with additional power inputs. My intention was to use exisiting HD in a similar setup - however my issue...

B+ and max_usb_current

I've had my B+ for a couple of weeks now with the intention of replacing an existing B with HD however I cannot get it to boot with max_usb_current=1 in config.txt (tried safe_mode_gpio=4 too). It cycles through the rainbow screen, I'm unable to read the console messages before it dies and restarts....
