Strange USB Kernel Build Problem OMAP-L137

Kevin Halloran
Expert 1345 points

Other Parts Discussed in Thread: DA8XX

This one doesn't make much sense but see if anyone has any ideas.  Am running Ubuntu under VmWare Windows.  Have an environment which was working fine for buiding kernels, then integrated DSPLink and GDB 6.8.  Things were fine until I went back and decided to build the kernel again and now can't mount root from USB pen drive anymore.  Even if use default TI configuration with USB/SCSI enabled.  To confirm I went to a backup Ubuntu VMWare image, and built, tested, fine, thus took that .config file to the problem installation figuring I was just missing something in xconfig.  Did a distclean, copied good .config file in, built, USB booting still won't work, see's the pen drive information and partition size.

Thought possibly USB pen drive roached so used the uImage from backup Ubuntu (prior to gdb and DSPLink) and same .config, boots fine.  Thus pen drive is fine.

Get's worse, figure something in kernel code is roached so extracted baseline linux-2.6.18_pro500 and used working .config, rebuilt...  USB same problem...  Saved off /opt/montavista and re-installed (removed any extra exports in .bashrc), rebuilt...  USB still not mounting root.  I can go back to backup Ubuntu and do the gdb and DSPLink again but may end up where am at now so would rather understand...  enabled debug messages for USB as well and didn't see anything.  Below is booting information if someone can see anything that knows area better than I.  Tried both low latency and PREEMPT builds (which is what I was using), but same issue.

What is weird is it can see the 16G pen drive enough to get below info and partition size?  Was wondering if with the additions of gdb/DSPLink caused a timing problem but I backed them out and still issue, almost like something is being picked up in the build that shouldn't be:

    Bit more info...  I changed things to boot NFS and I can mount the USB pen drive with no problem manually and no errors seen on device during boot, just when want to mount as root get timeout (option is selected in kernel build also remember .config is same as good uImage):

    Same uImage with USB booting problem now with uboot parameters for NFS root mount:

    Can you provide "bootdelay=10" as part of bootargs?  Probably this might make a difference.

    Thanks for the input.  Tried it and did not help.  Was set to 3 before and there is probably another 3 during TFTP load.  Same problem.  For the moment I'm booting with NFS but will eventually have to resolve it.  My guess is some sort of timing issue with loading drivers or something given exact same .config as a working uImage (without gdb 6.8 and DSPLink).  Even tried disabling most of the non-used USB options as well as NFS client but no difference.  Can mount manually with no problem once boot on NFS.

    I believe the correct argument is "rootdelay=10" and not "bootdelay=10". It worked for me.

    Also sdcard's write lock causes the same problem...  :)
