A10 lime and A20 lime Problems

[mrcotcot]

Hello,
i have bought 3 cards
one A20 lime, one A10 Lime and one A20 Lime2

one the A20 Lime2 all work perfectly (network, HDMI ....)
on the A20 Lime the network card seem be Down  , i thinks a ahev tested all methods for seeing my card on my network (DHCP by nm-connection manager, modify /etc/network/interface, using the standard command (dhclient eth0 ...) place a static IP on card) i dont see the A20 Lime on my network ...

on the A10 Lime.. the probleme is different, the HDMI seem HS . i don't have serial debug  cable for test the Boot Up. like the HDMI is off, i cant start the Network service, and i do'nt acces to my card with SSH

i have write to the support@olimex but i do'nt have response
i have two question
have you an image with a networking DHCP service already up for my A10-Lime
and an image with a valide configuration for finish to test my A20 lime

Thanks...

You need a debugging cable or you're just working blind.  They're almost free on ebay.

The hard way is to figure out - without it - what is going on.

ok i go to buy this "f.ck..g" cable today.
i thinks is a good way for my A10...

but for my A20, i can configure it whith a normal screen and keyboard...and ... the  network is already down.

more thanks john

have you just one good image (HDMI + network DHCP) for my A20_lime, i want test it ...

The images are good, you can read many people use them OK, so it's something about your set up.
