I can now confirm that my PCB supplier has now successfully fitted connectors P8, P8 and I have taken delivery of my first-off sample. Gerald, are you able to point me to some instructions on how I get my "virgin" beagleboardblack up and running? I have tried using an SD card with a known good android image but this does not work, the error I get from hyperterminal is:
U-Boot SPL 2011.09 (Nov 27 2013 - 10:43:10) Chipsee AM335x EVM Board Incorrect magic number in EEPROM read_eeprom() failure. continuing with ddr3 OMAP SD/MMC: 0 mmc_send_cmd: timedout waiting for cmddis! ** Can't read from device 0 ** spl: fat register err - -1 ### ERROR ### Please RESET the board ### I'm not surprised that it doesn't yet work because there must be some programming/setup to be done on the board itself before it will operate and this hasn't yet been done. I think I may have to program the E2..? Could you help me with that procedure please? On Tuesday, 18 February 2014 16:10:00 UTC, lee....@bibby-scientific.com wrote: > > Thank you Gerald.
