My B-Pi is unresponsive and seems to be playing dead......and after only using it for 3 days - having waited 10 days after ordering for it to arrive!!!
Worked fine with many Linux images (only via HDMI-DMI cable) and Android 4.2.2 (only via AV Video to analogue TV).
Power supply is 5V and 2A and is brand new!!
Two cards being used: a 16GB Class 4 SanDisk micro SDHC in Sandisk adapter (also tried with an Intenso adapter); and an 8GB Class 10 SanDisk Ultra normal size SDHC. Both worked without issue up till now.
This is what happened and this is what I did.
I was using Lubuntu when that OS crashed (mouse did not move cursor and clock time did not change for more than 30 minutes) so I pressed reset switch for 1 second.
Red light came on but no green light and it didn't reboot.
Tried different card with a known to be working Android 4.2 image. Still only red light (steady, not flashing), no green light.
Tried again with formatting a card (SD Formatter) then burning (Win32DiskImager) the Raspbian for B-Pi image - no boot.
Tried other Linux images from Downloads section. No success.
With SD card in slot, power on, the red light is on, press Reset for one second. Red light flashes, no boot.
Press Power switch for 5 seconds to completely shutdown, press again for one second, no boot.
Unplug micro USB from DC In, try again all the above. Try a different power supply. No boot
As far as I know, there was no static discharge nearby (but of course there does not need to be a visible spark).
I think it might be similar to http://forum.lemaker.org/2392-1-2-dram_error_please_reset_the_board__.html
But I don't know how to do the "serial console with Uboot procedure" (I think it needs a Linux computer and special cables to J11 via a TTL console, or??).
Any ideas? Or is it defective and I need to send it back to the supplier (in China!!!)??
Serial number is A202014061106834. Can someone at LeMaker check with the factory if there are any problems for other B-Pi's near this number?
