Dear Mr.Wolfgang Denk, Your reply had helped me a lot in figuring out the solution, but I run into another issue. I had identified the kernel file where load address is defined: kexec-bzimage64.c:#define MIN_KERNEL_LOAD_ADDR0x10 I am using the following command to create uImage. Here in

[U-Boot] uImage load address and entry point with Minnowboard

2016-06-22 Thread vinoth eswaran
Hello, I am working on an embedded project to optimize the boot time on minnowboard. Currently I am working with the u-boot. With compressed kernel (bzImage) everything works fine, I want to check the performance with uncompressed kernel (vmlinux). I have found that u-boot cannot support the raw
