JC 01:37 PM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

Are you applying your patch on top of these checkouts? Jonathan Cormier

DM 01:21 PM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

the usb port is stable on tag cl_v3.2_AM335XPSP_04.06.00.07
but Ethernet will not work. usb is unstable on tip AM335XPSP_04.06.00.02 branch, but Ethernet will work.
Any ideas? dan mcgee

DM 10:27 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

still a problem with usb on this branch. dan mcgee

AB 10:23 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

Could you post an updated patch to show what was changed to resolve the issue?
Thank you. Alexander Block

DM 10:04 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

thank you for the support dan mcgee

DM 10:01 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

commented out some of the pin mux structs and now Ethernet is working. dan mcgee

we are not using flash dan mcgee

JC 01:15 PM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

Also do you plan on using the nand? You have a module that has the larger 512MB nand which requires the latest u-boot and kernel image to work (See the CONFIG_NAND_MITYARM_LARGE_PAGE_SUPPORT option for the kernel and the mityarm335x_4kp... Jonathan Cormier

new patch file using format-patch --ignore-space-change dan mcgee

JC 01:08 PM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

I'm having a hard time finding the actual change in the patch. If you could recreate your patch ignoring white space change that would be much appreciated. Jonathan Cormier

JC 01:03 PM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

FYI, the kernel has very strict rules about formatting. In this case the use of tabs instead of spaces. Most of your patch is converting tabs to spaces which is a big no no for kernel code.
