Hi there is some problems on ethernet controller. My board use lan8720a and it do not support dynamic control ethernent clock well. So i let it normal on. And it solve the problem on kernel support by freescale.But it failed on uc 16. The ethernet port seem well but kernel freeze at here:
[ 3.412416] PPP Deflate Compression module registered [ 3.417746] PPP MPPE Compression module registered [ 3.422851] NET: Registered protocol family 24 [ 3.427632] ehci_hcd: USB 2.0 ‘Enhanced’ Host Controller (EHCI) Driver [ 3.434389] ehci-pci: EHCI PCI platform driver [ 3.439222] ehci-mxc: Freescale On-Chip EHCI Host driver [ 3.446244] usbcore: registered new interface driver usb-storage [ 3.453052] usbcore: registered new interface driver usbserial_generic [ 3.460276] usbserial: USB Serial support registered for generic [ 3.466906] usbcore: registered new interface driver option [ 3.472931] usbserial: USB Serial support registered for GSM modem (1-port) [ 3.480172] usbcore: registered new interface driver quatech2 [ 3.486346] usbserial: USB Serial support registered for Quatech 2nd gen USB to Serial Driver
if i use only one ethernet port it’s run well. the kernel is here. the drivers seem no different from freescale’s kernel. and i change the driver at /drivers/net/ethernet/freescale/fec_main.c
Do someone have some idea about this problem?Thanks.
