All,
I need additional U-boot features than the ones provided in the freescale version of U-boot. I have got the latest U-boot source and compiled it for the iMX28evk. The new U-boot seems to work fine. However, when it goes to start the kernel I just get:
Uncompressing kernel... done, booting the kernel.
And nothing else. I'm using the same kernel with both the original Uboot from freescale and the one I just built. The original U-boot boots it just fine.
Thanks,
Bills
We've been using mx28evk with Yocto, with mainline u-boot, for quite sometime ... so it really seem to be the console. Check the whole env as you might be using the wrong bootargs.
You need to use ttyAM for default FSL kernel and ttyAMA for mainline. You seem to use FSL kernel so change console variable.
Thanks. Yes I tried that previously (using ttyAMA0 - found it in another post) and it did not make a difference. I'm not sure about using the mainline Linux kernel. I was referring to the mainline U-boot with the existing kernel. However, I may try it with a mainline Kernel (just hope this does not "ripple" through and end up needed to upgrade a bunch of packages)
Thanks,
Bills
Hi Bills,
you need to change the console for Linux from console=ttyAM0,115200 to console=ttyAMA0,115200
Also note the wiki page at: http://imxdev.org/wiki/index.php?title=Running_a_mainline_kernel_on_a_MX28EVK_board
(easily found with google)
Kind regards,
