[U-Boot-Users] [Patch] U-Boot-V2: Kconfig Cleanup patch
by Menon, Nishanth 12 May '08

12 May '08

This is Kconfig cleanup patch (not all configurations will use CFI, SPI, RAMFS and DEVFS). * Enable CFI and SPI drivers menuconfig option to be able to disable them in menuconfig. * Introduce capability to disable ramfs and devfs.

[U-Boot-Users] [Patch] U-Boot-V2: Replace CONFIG_SKIP_LOWLEVEL_INIT with CONFIG_MACH_HAS_INIT_LOWLEVEL
by Menon, Nishanth 12 May '08

12 May '08

Hi Sascha, Based on http://sourceforge.net/mailarchive/forum.php?thread_name=20080508151609.GB9… This is the second separate patch which introducing Machine dependent init lowlevel config. Regards, Nishanth Menon This introduces CONFIG_MACH_HAS_INIT_LOWLEVEL which is the opposite of the current CONFIG_SKIP_LOWLEVEL_INIT. CONFIG_SKIP_LOWLEVEL_INIT which was used by ARM platform configurations previously, is made platform independent configuration. CONFIG_MACH_HAS_INIT_LOWLEVEL can be enabled to do board level initialization and disabled to allow U-Boot to function as the second level boot loader in certain scenarios by skipping SDRAM initialization.

"I tried a more complex code that uses a periodic interval timer to do a delay on flash LED code however this code does not work, It comes back to U-Boot shell with return value of 1. What can I be doing wrong?" -- to answer my own questions, the page http://www.denx.de/wiki/view/DULG/MyStandaloneProgramDoesNotWork did help because I was not going to the right entry point :-) Thank you all :-) :-)

[U-Boot-Users] help in understand the address of standalone applications, ARM MCU
by J.P. Casainho 12 May '08

12 May '08

Hello :-) I would like to create a standalone application and I already read manual and also asked help here and got one good example however I can't get It working and I think the problem is in the address. I am using an Olimex dev. board with a ARM9, AT91SAM9260 MCU. On my makefile I am linking with address 0xc100000, "LDFLAGS=-Bstatic -Ttext 0xc100000" -- is this address correct? How can I have sure of that? -- I got this value from makefile of "hello world" example. When I do "tftp 0xc100000 flash_led.bin" the system hangs.. while If I try to do for example "tftp 0x1000 flash_led.bin" the code loads ok but after "go 0x1000", the code does not work... It evens return while shouldn't because of an infinite loop on the code. In the manual of the dev. board I have a memory map that says the 64MB RAM starts at 0x20000000 and ends on 0x23FFFFFF - If I do "tftp 0x20000000 flash_LED.bin" system also hangs... Can someone help me? My flash_LED code is here: http://code.google.com/p/rockboxplayer/source/browse/trunk/flash_LED And the help, example, I got before here in the mailing list: http://code.google.com/p/rockboxplayer/wiki/Flash_LED I must say that with my dev. board comes an "hello world" example which is an empty function :-( -- but even I don't know to what address I should load it. I did turn ON and OFF the LED on the dev. board using U-Boot shell, using the memory write and memory display commands ;-) -- I did write configure values to the PIO controller, enabling the PA6 pin as output and set and clear that pin to turn OFF and ON the green LED. I am working on a Free/Open hardware digital audio player and recorder: http://www.rockbox.org/twiki/bin/view/Main/RockboxPlayer Thanks in advance, JPCasainho - http://www.Casainho.net

[U-Boot-Users] [PATCH] Fix offset calculation for multi-type legacy images.
by Nick Spence 12 May '08

12 May '08

Calculation of tail was incorrect when size % 4 == 0. New code removes the conditional and does the same thing but with arithmetic Signed-off-by: Nick Spence <nick.spence(a)freescale.com> --- The minimum change is to re-insert the original check: if ((uimage_to_cpu (size[i]) % 4) != 0) tail += (4 - uimage_to_cpu (size[i]) % 4); or a variation on this.
