Yeah, same issue here with the Samsung Evo. When I can get it to boot up it seems to work fine, but during boot up at around the "Populating udev" stage it gets corrupted most of the time.Xiol wrote:Hi,
I'm also having these issues on a brand new Samsung 16GB Evo Class 10 (specifically this one).
Like the OP, I'm having intermittent read issues on boot. Sometimes it'll come up fine and I'll have no issues once it's up - for example, I can write a 10G file to the SD card with no errors.
It does seem to happen about 40-50% of the time and will require a hard reboot to fix, at which point fsck runs to fix filesystem corruption.
I'm using the 'official' Raspberry Pi power adapter, bought from Pimoroni, that supplies 2A @ 5V, so I don't believe this is a power issue unless I've been supplied with a dud!
I had this issue on day 1. On first power-up we got a desktop for a few seconds then blank. 8 flashes indicates a problem with the RAM, apparently. I got it whether or not there was an SD card inserted. I thought it might have to do with an apparently untidy bit of soldering and was about to send the thing back. However on Day 2 all seemed well. (Did attacking the solder blob with a fingernail have an effect?) Not using NOOBS but the stock Raspbian and RISCOS also works on the same SD card.sacokid wrote:My experience is that the PI 2 will not boot NOOBS from 2 PNY cards ( 32 G and 16 G). The green light flashes 7-8 times and then repeats this sequence. However, both cards were used successful with an A+ and a B 512 using the same cables, display, power supply (2 a), and keyboard as used with PI 2. The PI 2 clearly has a problem.
I was using NOOBS 1.4 on a newly formatted SD. First tried to boot on the RPI2 which failed and then inserted the SD into an A+ which booted correctly. Next, I inserted the SD into a B 512 which also booted correctly. I repeated this process with two SD cards (PNY).DougieLawson wrote:Start with a fresh clean card. Download NOOBS 1.4 and try that.
