ahoj,

davam dohromady jeden taky hardware colibri..

"embedded" modul linuxovym kernelom priamo nieje podporovany (aj ked vsetky jeho sucasti podporovane su), takze bolo potrebne doplnit mikroarchitekturu pre kernel .. z nejakych existujucich patchov pre starsie kernely aj nejakych novsich neuplnych patchov sa mi podarilo dat dohromady funkcny kernel, busybox a nejak dat dohromady root filesystem.

funkcne bolo hadam vsetko zakladne co som potreboval (flash, ram, siet, usb, grafika, ...) okrem jednej hadam najdolezitejsej veci, ale tazko budem tvrdit ze nefunkcna, pretoze ono to nejak funguje.

konkretne funguju len pingy a NFS spojenie naviazane pocas bootovania kernelu root-nfs, kedy som ziskal aj IP adresu cez dhcp.

s konzoly modulu colibri to vyzera nasledovne:

vsetko vyzera uplne normalne a aj normalne funguje. dokonca aj web server je funkcny z lokalnej strany..

ine je to z druhej strany z PC...

Note: Host seems down. If it is really up, but blocking our ping probes, try -PN
Nmap done: 1 IP address (0 hosts up) scanned in 2.127 seconds

nmap nenasiel nic ani s parametrom -PN ... len ze vsetky porty su filtrovane, podobne to skoncilo aj pri teste UDP

skusal som rozne finty, ale stale to bolo podobne, aj som kernel funkcny a rootfs napalil do internej flash, potom sa cez program udhcpc snazil ziskat IP adresu, alebo nastavit IP rucne... hadam vsetko ... a stale to neslo.

... vyzera to asi na chybu hardwaru, ale potom preco funguju pingy a spominane NFS ? .. takze skor to bude asi chyba ovladacov v kerneli.. (v povodnom windows CE som to nestihol vyskusat)

nema stym (aj niecim podobnym) nahodou niekto skusenosti ??

dik za kazdu radu.

palo.
