how do i solve this problem relocation 28 out of range

[igorpadykov]

Hi jesse

this may be related with branch instructions in modules having a limited

range. You could  rearrange the placement of some sections within the kernel

image to eliminate the problem.

Best regards

thanks... but how to rearrange~~~?

my compat section in the /hardware not in the kernel_imx

modify vmlinux.lds.S ???

or

modify the directory build to another place like kernel_imx/drivers?
