[U-Boot] Boot uboot from another position in flash
by ich 10 Aug '11

10 Aug '11

Hello guys I use u-boot U-Boot 1.3.1 - stm24_0054 for sh (Board mb411) (STLinux 2.4) It is no problem to boot with u-boot from flash at 0x000000. But I have to install u-boot in another position in flash than 0x000000. I can also load the uboot from a u-boot loaded in RAM with jtag (with go 0xa0650000). In the Bootvector is a jump written in Assembly language like: ##################################### .text .org 0 mov.l start_addr, r0 mov.l p2_mask, r1 mov.l @r0, r0 or r1, r0 jmp @r0 nop .align 2 start_addr: .long 0xa0650000 p2_mask: .long 0xa0000000 .end ##################################### (I have no idea about assembly language; I just modified an existing code!) Here is hangs. No start at all. I used the CFG_MONITOR_BASE=0xa0650000 without success. Is the problem my U-boot or the assembly code? Thank you contumax

[U-Boot] OpenRD Ultimate SATA & SD
by Philip Hands 10 Aug '11

10 Aug '11

Hi, I've been trying to get a version of u-boot for OpenRD Ultimate that is willing to boot from all of NAND, USB, SD and SATA, and find that SD & SATA is still not possible with -rc1 as packaged for Debian (and it seems that nothing in the subsequent work in the master git would help, but if people tell me that it does, I'll give that a try). SATA throws an error in ide_preinit in drivers/block/mvsata_ide.c, and having looked into it, the second call to mvsata_ide_initialize_port is what fails. This is with a SATA drive plugged into the on-board SATA port, and with nothing plugged into the eSATA port. If I #undef CONFIG_SYS_ATA_IDE1_OFFSET in include/configs/openrd.h then the second mvsata_ide_initialize_port call is disabled, and I can then boot from SATA, but I've not got an eSATA drive to test whether it would have worked if I had one plugged in. I note that there is still something a little odd going on, since the drive seems to get detected twice: Marvell>> ide reset Reset IDE: Bus 0: OK Bus 1: OK Device 0: Model: HITACHI HTS723216L9SA60 Firm: FC2ZC50B Ser#: 091005FC1220NCHXGPLG Type: Hard Disk Supports 48-bit addressing Capacity: 152627.8 MB = 149.0 GB (312581808 x 512) Device 1: Model: HITACHI HTS723216L9SA60 Firm: FC2ZC50B Ser#: 091005FC1220NCHXGPLG Type: Hard Disk Supports 48-bit addressing Capacity: 152627.8 MB = 149.0 GB (312581808 x 512) but it seems to work OK anyway. As for the SD -- it detects OK, but seems to be unable to read more than a small amount of data from the SD card, as seen here: Marvell>> mmc init SDHC found. Card desciption is: Manufacturer: 0x1e, OEM "AB" Product name: "USD ", revision 1.0 Serial number: 93331321 Manufacturing date: 8/2010 CRC: 0x00, b0 = 0 mmc1 is available Marvell>> ext2ls mmc 0 <DIR> 1024 . <DIR> 1024 .. <DIR> 12288 lost+found 1433576 vmlinuz-2.6.32-5-kir at which point it hangs. If I take the same SD card, put it in an SD-to-USB adaptor and then access it via the USB, I can boot the kernel, whereas it just locks up when accessed as an SD, which also seems to point at it not being able to do more than a small read via SD. Any suggestions on how to diagnose what's going on here would be most welcome. I've tried pointing gdb at it, but it seems not to be doing breakpoints as I'd expect, so hints on how to get gdb working as well would be helpful (yes, I am rather new to this :-) Cheers, Phil. -- |)| Philip Hands [+44 (0)20 8530 9560] http://www.hands.com/ |-| HANDS.COM Ltd. http://www.uk.debian.org/ |(| 10 Onslow Gardens, South Woodford, London E18 1NE ENGLAND

Do i need to add history in each patch or first patch of a series patch? I mean if I am submitting 2 patches in series I define history in patch 1/2. Am I right? Thanks & Regards, Ajay Bhargav

From: Manjunath Hadli <manjunath.hadli(a)ti.com> These are some of the patches which add features like NOR support and a couple of fixes. Fixes from last version from Denk and Withers's comments: 1. fixed commit message for cache usage patch 2. removed unnecessary undefs 3. used hwconfig for DSP wake patch instead of a new env variable. 4. used clearbits macro instead of read and write. Also dropped 4 patches for submission later.

[U-Boot] Custodians, please remove tag NIOS2-5_0_0 from your repos
by Albert ARIBAUD 10 Aug '11

10 Aug '11

Hello all, This tag NIOS2-5_0_0 keeps lingering in ARM repositories and should not be there. I regularly have to remove it from u-boot-arm because I keep catching it occasionally when recreating my u-boot-arm local copy and then fetching another ARM repo such as u-boot-atmel, u-boot-marvell, u-boot-pxa, u-boot-samsung, and u-boot-ti, which all contain this tag. Custodians should remove this tag from their respective repos, except Scott McNutt of course, who owns The Vote as far as keeping NIOS2-5_0_0 in u-boot-nios is concerned. :) This should be done in your remote (so that others don't catch it from you) and in your local working repo (so that you don't risk pushing it again on your remote), by executing respectively: git push ssh://gu-xxx@git.denx.de/u-boot-xxx :NIOS2-5_0_0 and git tag -d NIOS2-5_0_0 Thanks in advance! Note that this tag may exist in non-ARM repos -- I don't fetch any except u-boot itself (where this tag is not), so I can't tell, and won't be able to notice, if they are removed or not in those non-ARM repos. Amicalement, -- Albert.
