Hi, First of all i'm not sure if it is the correct list for posting this mail, if it's not, please tell me wich list is the correct one. I'm working on an embedded device (a Ronetix pm9261 board with an AT91SAM9261 cpu), i could build the linux kernel version 2.6.19.7 with framebuffer support and it works fine. The problem is when i run any command that uses net services, i.e. when i run sftp the sreen moves and it kept like this, the offset (0,0) is in position (100,0) (it's just an example, i don't know thw correct values) and i'm not able to correct it. It occurs every time i run a net comand. The display i'm usin is a LCD and the driver is sidsab.c.
Strange behavior is not it ;-) I have seen this before and it was due to a bad timing setup of the dm9000 chip select. - at91_sys_write(AT91_SMC_CYCLE(2), AT91_SMC_NWECYCLE_(0) | AT91_SMC_NRDCYCLE_(16)); + at91_sys_write(AT91_SMC_CYCLE(2), AT91_SMC_NWECYCLE_(16) | AT91_SMC_NRDCYCLE_(16)); Is you have the first configuration, try with the second and it should fix your problem. Hope that it helps. Tell us if it works.
