lucif | Bonjour,
Je dois installer une carte ep8555 (powerquicc) avec un noyau Linux dessus.
Tout se passe bien jusqu'au moment où je dois utiliser NFS pour mettre des repertoires dessus.
Je me connecte avec Uboot sur Linux à la carte et je tape ces commandes pour obtenir le noyau linux avec NFS:
> tftpboot 0x300000 zImage.gz
> bootm 0x300000
voici ce qu'il me dit :
Code :
- ep=> bootm 0x300000
