My old 256M Raspberry Pi shows odd headless boot behaviour it will not boot headless (SD green access briefly, but no ethernet lights). Official Raspian SD from ele14 that has been updated.
- Cold boot, no monitor, no boot, no ethernet lights.
- If I add a monitor thru hdmi2vga converter, cold boot OK, ethernet OK.
- If I remove the monitor and 'sudo reboot' (without disconnecting power) it boots OK, ethernet OK.
- If I power off and on with no monitor it does not boot (SD access blinks a few times) & no ethernet lights. Even if I wait.
/var/log/syslog seems not to have anything useful - like nothing being logged during failed boots.
