[U-Boot] Hanging in kmalloc of nand_scan_tail() function
by J.Hwan.Kim 15 Nov '10

15 Nov '10

Hi, everyone I'm using U-boot 2009-03. U-boot hangs in nand_init() function. I found the routine kmalloc in nand_scan_tail() cause U-boot reset. int nand_scan_tail(struct mtd_info *mtd) { int i; struct nand_chip *chip = mtd->priv; if (!(chip->options & NAND_OWN_BUFFERS)) { chip->buffers = kmalloc(sizeof(*chip->buffers), GFP_KERNEL); } if (!chip->buffers) return -ENOMEM; ........ U-boot displays message as follows : NAND: data abort pc : [<31f902b4>]\0x09 lr : [<31fa084c>] sp : 31f5bee0 ip : 00000076\0x09 fp : 00000000 r10: 00001188 r9 : 00020000\0x09 r8 : 31f5bfdc r7 : 00000001 r6 : 00000000\0x09 r5 : 31fa42b8 r4 : 31fa4364 r3 : 31fa052c r2 : 00000064\0x09 r1 : 00000063 r0 : ffffffff Flags: NzCv IRQs off FIQs off Mode SVC_32 Resetting CPU ... Where the malloc function is defined? Why the kmalloc() hangs the u-boot? Is there any configuation definition needed? Thanks in advance. Regards, J.Hwan Kim

[U-Boot] Is the Numonyx's M29W128 fully supported in U-Boot?
by txema lopez 28 Oct '10

28 Oct '10

Hi all, We have a MPC5200B custom board and we are evaluating the Numonyx M29W128 Flash as a second source for the Spansion's S29GL128. I've checked the top of the tree version of the U-Boot (u-boot.git) CFI driver and the Numonyx Flash is not detected. This is the U-Boot debug output: FLASH: flash detect cfi fwc addr fe000000 cmd f0 f0 8bit x 8 bit fwc addr fe000055 cmd 98 98 8bit x 8 bit is= cmd 51(Q) addr fe000010 is= 0 51 fwc addr fe000000 cmd f0 f0f0 16bit x 8 bit fwc addr fe0000aa cmd 98 9898 16bit x 8 bit is= cmd 51(Q) addr fe000020 is= 5100 5151 fwc addr fe000000 cmd f0 00f0 16bit x 16 bit fwc addr fe0000aa cmd 98 0098 16bit x 16 bit is= cmd 51(Q) addr fe000020 is= 6d69 0051 fwc addr fe000000 cmd f0 f0f0f0f0 32bit x 8 bit fwc addr fe000154 cmd 98 98989898 32bit x 8 bit is= cmd 51(Q) addr fe000040 is= 4e6f7620 51515151 fwc addr fe000000 cmd f0 00f000f0 32bit x 16 bit fwc addr fe000154 cmd 98 00980098 32bit x 16 bit is= cmd 51(Q) addr fe000040 is= 4e6f7620 00510051 fwc addr fe000000 cmd f0 000000f0 32bit x 32 bit fwc addr fe000154 cmd 98 00000098 32bit x 32 bit is= cmd 51(Q) addr fe000040 is= 4e6f7620 00000051 fwrite addr fe000000 cmd f0 f0f0f0f0f0f0f0f0 64 bit x 8 bit fwrite addr fe0002a8 cmd 98 9898989898989898 64 bit x 8 bit is= cmd 51(Q) addr fe000080 is= 0000000000000000 5151515151515151 fwrite addr fe000000 cmd f0 00f000f000f000f0 64 bit x 16 bit fwrite addr fe0002a8 cmd 98 0098009800980098 64 bit x 16 bit is= cmd 51(Q) addr fe000080 is= 0000000000000000 0051005100510051 fwrite addr fe000000 cmd f0 000000f0000000f0 64 bit x 32 bit fwrite addr fe0002a8 cmd 98 0000009800000098 64 bit x 32 bit is= cmd 51(Q) addr fe000080 is= 0000000000000000 0000005100000051 fwrite addr fe000000 cmd f0 00000000000000f0 64 bit x 64 bit fwrite addr fe0002a8 cmd 98 0000000000000098 64 bit x 64 bit is= cmd 51(Q) addr fe000080 is= 0000000000000000 0000000000000051 not found ## Unknown FLASH on Bank 0 - Size = 0x00000000 = 0 MB This is the debug output for the Spansion Flash that works fine.

So I think the Numonyx Flash has been tested in some boards but I don't knwon if there is full support in U-Boot for it. If not, is there a patch available or in process? Any clue will be welcomed. TIA,

[U-Boot] [PATCH v6 0/10] PPC LBC/TLB cleanups; reginfo command for 85xx
by Becky Bruce 26 Oct '10

26 Oct '10

This somewhat random patch series got its start when I was asked to create a reginfo command for 85xx by one of the internal teams here at FSL to dump the BR/ORs, LAWs, and the TLBCAM entries. As I started doing that, I began to notice that there was a lot of duplicated and inconsistent code for manipulating the TLBs and LBC registers, which, in some cases, would have caused me to have to write extra code to make reginfo useful on multiple platforms. So I decided to clean this up. The bulk of these patches are just merges of duplicated code and renames of things to get to a consistent naming scheme. These really need to be picked up by a single maintainer, as there's a definite dependency chain here; I'll let Kumar and Wolfgang decide who wants it. Changes from last rev: Fix whitespace, missing signoff, added Kim's Acks. Diffstat below.

[U-Boot] usb EHCI failing with 'EHCI fail timeout STD_ASS reset'
by Dan Lykowski 21 Oct '10

21 Oct '10

Hi everyone, I've seen this question posted a few times in the past with no answer. Since I was having the same problem, I thought I would share the solution I came up with. I'll try to provide a patch if I can get my mess cleaned up. After some digging, I was able to see the EHCI HC getting a Master Abort over the PCI bus. It turns out that some.. all??.. PCI EHCI controllers have 64-bits for the buffer registers in the qTD structure. See Appendix B in the EHCI specification. This is what I changed the qTD structure to. /* Queue Element Transfer Descriptor (qTD). */ struct qTD { uint32_t qt_next; uint32_t qt_altnext; uint32_t qt_token; uint32_t qt_buffer[5]; uint32_t qt_buffer_hi[5]; uint32_t unused[3]; }; Adding the qt_buffer_hi array, realigning the buffers on 32-byte boundries, and filling qt_buffer_hi with zeros when qt_buffer is being filled fixes the problem. Thanks, Dan Lykowski

[U-Boot] [PATCH] always relocate fdt into an lmb-allocated memory block
by Timur Tabi 20 Oct '10

20 Oct '10

The device tree (fdt) must always exist in within the bootmap (usually the first 16MB of RAM). If it doesn't, then boot_relocate_fdt() will allocate an LMB region in the bootmap and copy the fdt into that region. It will also increase the size of the fdt. If the fdt is already in the bootmap, then previously the memory was just reserved. There was no contingency if the reservation failed, however. By always allocating an lmb region and copying/resizing the fdt into that region, the code is simplified and the memory region is always allocated properly. Also change the types of some variables to avoid some typecasts.

[U-Boot] [PATCH 2/2] Remove AmigaOneG3SE board
by Wolfgang Denk 14 Oct '10

14 Oct '10

The AmigaOneG3SE board has been orphaned or a very long time, and broken for more than 12 releases resp. more than 3 years. As nobody seems to be interested any more in this stuff we may as well ged rid of it, especially as it clutters many areas of the code so it is a continuous pain for all kinds of ongoing work.

[U-Boot] [PATCH] examples/standalone: Remove relocation compile flags for PowerPC
by Peter Tyser 12 Oct '10

12 Oct '10

Previously, standalone applications were compiled with gcc flags that produced relocatable executables on the PowerPC architecture (eg with the -mrelocatable and -fPIC flags). There's no reason for these applications to be fully relocatable at this time since no relocation fixups are performed on standalone applications. Additionally, removing the gcc relocation flags results in the entry point of applications residing at the base of the image. When a standalone application was relocatable, the entry point was generally located at an offset into the image which was confusing and prone to errors. This change moves the entry point of PowerPC standalone applications from 0x40004 (usually) to 0x40000. Signed-off-by: Peter Tyser <ptyser(a)xes-inc.com> --- I tested this on an 8548-based board and it worked as described above. It wouldn't hurt if a few others tried it out to validate that the new entry point is always 0x40000. examples/standalone/Makefile | 8 ++++++++ 1 files changed, 8 insertions(+), 0 deletions(-) diff --git a/examples/standalone/Makefile b/examples/standalone/Makefile index 6ea3b93..0c8dbe7 100644 --- a/examples/standalone/Makefile +++ b/examples/standalone/Makefile @@ -72,6 +72,14 @@ gcclibdir := $(shell dirname `$(CC) -print-libgcc-file-name`) CPPFLAGS += -I.. +# For PowerPC there's no need to compile standalone applications as a +# relocatable executable.
