I fear they will incur additional issues of setting LD_LIBRARY_PATH, due to absolute paths in the binaries.

Sure. I updated the log in the ticket [4]. Sadly, it seems to make the issue only worse, as the boot is now stuck even earlier. Best regards, V.

Hi Peter, Thanks for your concern! I have updated the bugzilla Bug 103461 with more details, to spare the list. Do not hesitate to let me know if you need any additional details. Hi Vincent, Since I can't find the app running at linux pc at bugzilla, I use Freescale's Mfgtool to have a try, but can't reproduce it. Would you supply below: 1. The u-boot.bin which you use to reproduce it 2. The application used to load u-boot.bin from pc, and related script 3. Instruction how to use the tool to reproduce the failure Meanwhile, Would you please enable chipidea debug at kernel configuration, and add 'debug' at your u-boot command line to run it again, I would like to see the log if possible?

Vincent, would you supply related u-boot and pc tools for me? Then, I can reproduce it. This issue should be due to access register without clock, normal kernel boot can't reproduce it. -- Best Regards, Peter Chen -- To unsubscribe from this list: send the line unsubscribe linux-usb in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
