All,
I have had problems getting the dm9000 mac/phy working properly with the DM355 EVM. I have seen a number of posts indicating problems with the dm9000 and the DM355. When using the dm9000 on a local network with little traffic then things seem to work properly. If I put the unit on a network with a lot of traffic then I couldn't ping or telnet to the unit. I compared the 2.6.18 kernel and the 2.6.28 kernels and found an interesting difference. The 2.6.18 kernel requests the individual interrupt for GPIO1 (IRQ 45) where the 2.6.28 kernel uses the gpio controller interrupt (IRQ 65) which is chained to the bank interrupt. By changing the 2.6.28 kernel to reflect what I saw in the 2.6.18 kernel this seemed to solve the problems I was seeing. Are there known issues with the DM355 gpio controller interrupt handling where it chains the individual interrupts to the bank interrupt? --tmw Tom Wheeler | Sr. Software Engineer ____________________________ Control4 11734 South Election Road Salt Lake City, Utah 84020-6432 United States p. 801.523.3175 f. 801.523.3199 e.
