Thank you, John. Using the config file you provided, I recompile the entire project. And then Linux can run well. At 2017-06-16 21:32:09, "John Backes" wrote: Okay. I have made that same mistake and had similar symptoms as what you are describing. Just to be clear you should use the Image found in: buildroot/output/build/linux-custom/arch/arm/boot/Image Are you sure that you are compiling the kernel to boot from a ramdisk? I think when I did this I may have had to do a make menuconfig in the linux source directory to set this configuration. I was only ever able to get this to work by setting the option to boot from a ramdisk appended to the binary. I've attached my defconfigs from when I last did this. - John On Fri, Jun 16, 2017 at 8:19 AM, li94575 wrote: I'm sure I use the decompressed binary.
