[U-Boot] What mkimage arguments for standalone AVR32 app?
Hi list
I'm trying to create a standalone application for the ICnova ap7000 Base
and have compiled this little application:
#include avr32/io.h
int main( void )
{
__asm__(nop\n\tnop\n\tnop\n\tnop\n\t);
while(1)
{
;
}
return 0;
}
To create the header file for it I use this mkimage command:
mkimage -A avr32 -O u-boot -T standalone -C none -a 0x1100 -e
0x1100 -n myapp -d test.bin test_uboot.bin
but when i try to execute it i get this error:
ICnova tftp 1100 test_uboot.bin

Currently it seems that all in-tree boards can be accomodated with the construct that I suggested. I am not at all sure that we want code which is only used by out-of-tree ports. Post the port and we can rediscuss new code. Full ACK here. It makes no sense to spend time and resources on sup- porting out-of-tree ports on broken hardware. Ok, that's fine by me. That's by the way not much different to the state before my change. You always had local changes as there was never support for 16-byte strides.

the entry/load addresses need to match reality. you cant pick them out of

air without properly setting them everywhere.
you also didnt say how you compiled/linked the standalone code ... you must
be
sure to not use any files/libraries/toolchain that expect an operating system

Here's how i compiled it:
avr32-gcc -O2 -Wall -c -fmessage-length=0 -mpart=ap7000
-ffunction-sections -o test.o test.c
avr32-ld test.o -e 0x -T simple.lds -o test.out
avr32-objcopy -O binary test.out test.bin
And the simple.lds:
SECTIONS
{
. = 0x1100;
/*. = 0x; */
.text : { *(.text) }
/* . = 0x800; */
.data : { *(.data) }
.bss : { *(.bss) }
}
and a objectdump:
avr32-objdump -d test.out
test.out: file format elf32-avr32
Disassembly of section .text.main:
1100 main:
1100:d7 03 nop

ICnova tftp 1100 test_uboot.bin
ICnova bootm 1100
Load Address: 1100
Entry Point: 1100
you shoulud not load (tftp) the bootable image to the same address that it
will be uncompressing to (load address).
really you should read doc/README.standalone and the simple examples in
examples/ instead of trying random commands.
-mike
According to the Makefile in the example directory i should load the
binary to 0x
ifeq ($(ARCH),avr32)
LOAD_ADDR = 0x
endif
but looking at the uboot startup it says that the flash is placed at
that address and that the SDRAM is placed at 0x1000.
Flash: 8 MB at address 0x
SDRAM: 64 MB at address 0x1000
Which of the addresses should i use?
I couldn't find any documentation about what entry address i should use
for the avr32 but according to the README.standalone it is only the
power pc which needs a entry address different from the load address so
i guess load address=entry address.

On Tue, May 05, 2009 at 12:58:57AM +0200, Wolfgang Denk wrote: the usb driver use the same file for supporting all the PXA and as it's store in a generic header. We must define the register only the specific pxa version and when the same register could mean differents things depending the pxa version That's the theory. Praxis is that we have a bug, and we need a fix. And we seem to have one. Correct. It does not build anymore. Another possibility is to revert the commit which caused the trouble and make Markus Klotzbuecher fix it in a way Jean-Christophe PLAGNIOL-VILLARD likes. - how many PXA platforms with USB support do we have? That's not the point. I for myself won't bring my board support into U-Boot's mainline (at least not now) because that would help nobody as nobody except for me has the hardware the code was written for. And I guess I'm not the only one. IMO hings should compile, even when the config for this is not in your repository; hope you agree. In other words - is your concern a real problem, or just a theoretical one? Code using that macro is guarded by MONAHANS #ifdefs anyway, his point is solely not to have it in the register headers.

[U-Boot] [PATCH] ARM: unbreak PXA build by defining UP2OCR
U-Boot does not currently build for PXA platforms with USB support enabled. This is due to commit 24e37645e7378b20fa8f20e2996c8fb8e9 which introduced the usage of UP2OCR without defining it.

[U-Boot] U-BOOT kgdb support for ARM920T (s3c2440)
I've just written and tested this kgdb patch for ARM920T cpus.
The development was aimed at providing a low-cost cross-debugging
environment for a Samsung ARM board produced from SERP (www.serp.it)
used in an Computer Architecture course taught at the university of
Padova (IT) (www.dei.unipd.it).
It works with gdb software breakpoint (on the host computer). Also
with an arm-linux- toolchain.

[U-Boot] [PATCH 0/3] OMAP3: Minor code clean up, no functional change
This patch series is an attempt (*) to help with [1] and the first part of [2]. It contains only minor code clean up, no functional changes. Complete patch series boot tested on OMAP3 BeagleBoard and compile tested with ./MAKEALL ARM_CORTEX_A8. I'm unsure about two topics: * The initial ideas and patches for these changes are all from Jean-Christophe (*). So I added Jean-Christophe's From: and Signed-off-by:. If this is wrong, please correct. * Patch 2/3 renames interrupts.c to timer.c. In git this can be done easier by just rename. But for testing and sending it as patch to be applied I had to do it this way. Maybe the rename could be done easier while applying the patch to git?

[U-Boot] powerpc: why call unlock_ram_in_cache() only for e500 cores and linux?
For the powerpc architecture there are 2 locations that I see caches being unlocked for those boards which lock a cache for use as early memory: - lib_ppc/board.c, line 757 in board_init_r() #if defined(CONFIG_SYS_INIT_RAM_LOCK) defined(CONFIG_E500) unlock_ram_in_cache(); /* it's time to unlock D-cache in e500 */ #endif - lib_ppc/bootm.c, line 74 in boot_jump_linux() #if defined(CONFIG_SYS_INIT_RAM_LOCK) !defined(CONFIG_E500) unlock_ram_in_cache(); #endif I had a few questions about this and was hoping someone had some insight: 1. Why is the cache only unlocked for e500 cores in board.c? It seems like the cache should be unlocked for all processor types in board.c. I was under the impression any data which was initially stored/referenced in the cache as RAM early in the boot process was not needed after relocating to SDRAM. I've tried unlocking an mpc8640's cache in board.c and the board appears to function normally to (somewhat) support this. 2. Why is the cache only unlocked when booting Linux for non-e500 processors? Shouldn't the cache be unlocked before booting all OSes? For example, from what I can tell, the reference VxWorks BSP for the mpc8641 expects the caches to be unlocked/enabled when booting and has issues when booting with the L1 cache locked. It seems like unlocking the cache for all CPUs in lib_ppc/board.c would provide a slight performance boost as well as a bit of consistency, while I'm not aware of any downsides. Based on the git changelogs, it looks like the 86xx and 83xx architectures used to have some bugs related to unlock_ram_in_cache() (d685b74c64a38849f1a129b3ab846fbf67dd937e use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache). Perhaps these bugs were the reason that caches were only unlocked for e500 cores?

[U-Boot] [PATCH] u-boot-v2 initrd support for ARM
Hi,
here's a small patch to make initrd working on ARM in u-boot-v2.
I use it to boot over the network like this:
tftp /tftpboot/kernel.uImage kernel
tftp /tftpboot/rootfs.uImage rootfs
bootm -r rootfs kernel
I create the rootfs image like this:
mkimage -A arm -O linux -T ramdisk -C none -a 0xA080 -n rootfs \
-d rootfs.cpio.gz rootfs.uImage
(this is for imx27)
regards,
Eric
