Can you access the SD card in a PC ?. On a Windows box you can see one small partition with a few files in it :
Code: Select all
bootcode.bin fixup_cd.dat kernel_cutdown.img start_cd.elf
cmdline.txt fixup.dat kernel_emergency.img start.elf
config.txt issue.txt kernel.img
On a Linux box, you can see both partitions.
No green light at all generally means its falling at the first hurdle - it can't find it's firmware on the small boot partition - the one you can see in Windows.
TP1 is quite near the the power connector. TP2 is between the GPIO pins and the composite video socket (Yellow on mine, ) They are both marked. I can't remember which is which (+/-) but it won't do any harm if all you're connecting is a voltmeter. Most digital meters will read a minus voltage if connected the wrong way round.
Don't judge Linux by the Pi.......
I must not tread on too many sacred cows......
