Warning Unable To Open An Initial Console. Busybox

The kernel still persists that it cannot open console. This will also make all init's messages to not be visible.

To me it seems as the partition/filesystem you provide within your bootloader either does not have the required modules inside the initram or is just plain wrong.

Can you get some additional printk's in there to report progress? All necesary binaries and utilities are compiled and placed in rootfs image. I am working on getting some printk's in there but was hoping someone could point out something obviously wrong with my approach before I went crazy with that. –dag May 3

It is on the wiki, but i think not at the right place ( chronological order).

busybox# 139 busybox# env - busybox# echo $? At this time, the only progress I had is that I managed to remove the "unable to open an initial console." warning.

After testing and rebooting my target several times (it may happen after hours of testing) I suddenly receive a message:â Warning: Unable to open an initial console.â, which means what /dev/console Then use objdump and readelf to compare executables and find out what is wrong. -- vda Previous message: Busybox init problem Next message: Busybox init problem Messages sorted by: [ date Recent Msgs:fedora-users/2016-12/msg00573.htmlubuntu-bugs/2016-12/msg11908.htmlserver-dev.james.apache.org/2016-12/msg00080.htmlscm-fedora-commits/2016-12/msg12112.htmlubuntu-bugs/2016-12/msg11938.htmlflightgear-sim/2016-12/msg00425.htmldev-felix-apache/2016-12/msg00184.htmlgeneral/2016-12/msg30402.htmlgeneral/2016-12/msg30408.htmlcommits.gnome/2016-12/msg04857.html Latest News Stories: Linux 4.0 Kernel Released Google Lets SMTP Certificate Expire Open Crypto Audit Passes TrueCrypt CIA 'tried to crack security of Apple devices' Xen Security Bug: Amazon, this contact form RedBoot partition parsing not available Using physmap partition information Creating 3 MTD partitions on "physmap-flash.0": 0x00000000-0x00020000 : "u-boot" 0x00020000-0x007f0000 : "root" 0x007f0000-0x00800000 : "env" i8042.c: i8042 controller self test timeout.

Do you still get "Warning: unable to open an initial console" just above this line?

After adding printk's so that I better understood the startup sequence, I realized that console device is opened prior to running the init script.

I still can telnet to the target and what I stated is that /dev/console changed major/minor numbers from official (and initial) 5,1 to 0,5. I expect that uImage does not know how to proceed on. I will post the answer in case anyone else has this issue. All works now.

If yes, this is definitely a problem with /dev/console not being found.
