Re: [U-Boot] initramfs support through the initrd mechanism of u-boot

Hi Thomas, Le 15/07/2011 09:53, Cao, Da-Shi (EB-Presales-ZTE/HW-GZ) a écrit : > Hi Albert， > I did not know how to make a uImage of initrd. I guess u-boot does not support the gzipped cpio as an initrd. As I'm new to u-boot, so I would be glad if I can make the gzipped cpio to be acceptable by u-boot as a valid initrd. This is something that you can probably find answers to in Denx' ELDK -- see the Denx website. > As for the physical address, it is in the file arch/arm/mm/init.c of Linux kernel. It works when I pass a physical address of initrd to it. It seems that if the old format of initrd is passed to Linux kernel, it expects a virtual address! > > I can either change the init.c of Linux kernel to expect a virtual address, or change the u-boot to give a physical address. It is more dependable to make u-boot send out a physical address, as the virtual address of u-boot may not be the virtual address of the Linux kernel, although it is now identical for current moment. I am surprised that U-Boot provides a virtual address. If you are sure that it does -- i.e. if you have traced the current (git u-boot/master) U-Boot code and made sure that the address passed is not correct as a physical address and is correct as a virtual one, then please open a new discussion thread here with an adequate subject and mention the exact SW and HW setup you're using, along with your observations. > Thanks a lot. > Thomas Amicalement, -- Albert.

[U-Boot] at91rm9200 undef runtime error with eldk 5.0
by zzs 16 Jul '11

16 Jul '11

Hi, everybody: I'am using a board similar to at91rm9200ek, u-boot version is v2011.03. Early I use eldk4.2 to build u-boot, all things ok, but eldk 4.2 can't compile busybox whith ubiattach enabled. So I change my toolchain to eldk5.0 (eldk-eglibc-i686-arm-toolchain-gmae-5.0.tar.bz2, poky-image-sato-sdk-armv5te.tar.gz). Now the make process all ok. But when download u-boot.bin to the board. the code say: -F- Undef detected eldk5.0-armv5te CAN'T used for arm920t ??? Is this true? anybody help me! -- Best Regards, zzs

[U-Boot] Hello
by Nadia Omwony 16 Jul '11

16 Jul '11

Hello It is with profound respect and humble submission, I beg to state the following few lines for your kind consideration. I hope you will spare some of your valuable minutes to read the following appeal with sympathetic mind. I must confess that it is with great hope, joy and enthusiasm to write you this mail and I believe by the faith that it must surely find you in good condition of health. My names are Miss. Nadia Omwony Ojok, Ugandan Citizen, female, age 23 years old. I`m the daughter of Late Mr. Omwony Ojok, former minister for state in charge economic monitoring. My father died in the Intensive Care Unit of Mulago Hospital due to suspected heart failure. I lost my mother longtime ago when I was just 6yrs old, and since then my father took me so special.Before the death of my father, he told me that he made a fixed deposit of the sum of Four Million, two Hundred thousand United States Dollars( 4.2Million USD ) in one of the Banks in Burkina Faso with my name as his next of kin. I have travelled to Burkina Faso to clear the money but the bank manager whom I met in person told me that my refugee status is not authorised by the laws of Burkina Faso to clear the money. He advised me to appoint a trustee. Now, I am Soliciting your help for transfer of the money into your bank account and investment assistance in your Country. I have suffered lots of set back as a result of my parents death. I left Uganda because of incessant family feuds. Presently, I am living in Ouagadougou,Burkina Faso. Hence, I want to settle abroad to continue my studies and spend the rest of my life. Please consider my request as my life is being hugely affected . I will send you the telephone number of the Church Mission where I am presently staying should you want to talk to me on phone. Thanks in anticipation of your prompt response. Yours sincerely, Nadia Omwony Ojok.
