[U-Boot-Users] Software upgrade using U-boot
by hemant kumar 13 Aug '07

13 Aug '07

Hi All, I have a linux 2.6 kernel running on ARM9 based target. i have a U-Boot as boot loader. I need to do a software upgrade.I am explaining my approach :- My system is having a well defined GUI with touch screen on it.So when running linux application with GUI and touchscreen user can send a command that he wants to upgrade the software ( include kernel + root file system + application) via touchscreen GUI. As far as my understanding goes i think application need to write something on flash( let us say change flag=1) so that next time when system reboots it U-boot read the variable status from same flash location so that it should not boot from flash and use tftfp downlaod and when download gets completed it changes the status of variable in order to make u-boot loading image from flash for next time onwards. Is it possible to do the software upgrade like the way i have explained , if not pls suggest a better way of doing it using U-boot.But my only requirement is, i dont want to go to U-boot command prompt and do the upgrades manually. I need some kind of automatic approach which basically start when my application is running. Thanks KVM ----- Forwarded Message ---- From: "u-boot-users-request(a)lists.sourceforge.net" <u-boot-users-request(a)lists.sourceforge.net> To: goforhemant(a)yahoo.com Sent: Monday, August 13, 2007 11:37:48 AM Subject: confirm 4543b731a50e1ede9a5a508a8182f823f5cdb6ca Mailing list subscription confirmation notice for mailing list U-Boot-Users We have received a request from 10.3.1.94 for subscription of your email address, "goforhemant(a)yahoo.com", to the u-boot-users(a)lists.sourceforge.net mailing list.

[U-Boot-Users] A question about _armboot_start
by Yang, Zhi 13 Aug '07

13 Aug '07

I am now studying uboot, and have some confusion about the Arm related boot code. In the specific board code file Start.S: _armboot_start is the address of the beginning of the start.o, and TEXT_BASE is the beginning address of boot code relocated in RAM, but when in the file lib_arm\board.c, there is a statement in the function start_armboot : gd = (gd_t*)(_armboot_start - CFG_MALLOC_LEN - sizeof(gd_t)); it seems that here _armboot_start is equal to TEXT_BASE???? but _armboot_start and TEXT_BASE both are constant, does it mean _armboot_start can be channged during relocating? how it happened?

Dear Wolfgang, Sorry for the delay, I was floating down Stony Creek with my family and thus was, of necessity, unplugged. ;-) <http://maps.google.com/maps?f=q&hl=en&geocode=&ll=43.558874,-86.496735&spn=…> If you look closely, you will see me waving as the satellite went over. Please do a git pull of the fdt branch: git pull git://www.denx.de/git/u-boot-fdt fdt The following changes since commit 29eaae953476f2bba4d5c7ac097b96cd827c1dff: Gerald Van Baren (1): Merge git://www.denx.de/git/u-boot are found in the git repository at: http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot/u-boot-fdt.git Gerald Van Baren (17): libfdt: Conditionally compile based on CONFIG_OF_LIBFDT Improve error messages, more informative. Minor code clean up. Improve fdt move length handling. Fix bugs in the CONFIG_OF_LIBFDT Reorganize and fix problems (returns) in the bootm command. FDT command improvements. Fix cmd_fdt line lengths, refactor code. Replace fdt_node_offset() with fdt_find_node_by_path(). Add fdt_find_node_by_type() and fdt_find_compatible_node() to LIBFDT For fdt_find_node_by_path(), handle the root path properly. Fix fdt_chosen() to call ft_board_setup(), clean up long lines. Asthetic improvements: error messages and line lengths. Tighten up the error messages. Create new fdt boardsetup command, fix bug parsing [] form of set values. Call ft_board_setup() from the bootm command. Improve error print messages.
