[U-Boot] Can't start Linux if U-Boot built with CONFIG_WATCHDOG
by Matthew Lear 26 Aug '15

Hello all, I've added watchdog support based on U-Boot (git) for the m68k coldfire mcf54455evb platform. I've fed the patch to the maintainer to help in development. However, I am unable to start my m68k w/MMU coldfire Linux kernel from U-Boot if U-Boot is built with CONFIG_WATCHDOG regardless if the watchdog_enable(), watchdog_reset() and watchdog_disable() functions touch hardware or not. I initially thought this was a problem with enabling the watchdog somehow (ie when Linux started, some hw configuration in the device was getting upset or corrupted etc resulting in the failure), but when I commented out the code from the above functions that actually accesses the hw (ie to enable, kick and disable the watchdog timer hw block), Linux is still unable to start. In fact, I don't think Linux actually gets started! That's the problem. If I rebuild the same U-Boot code base with CONFIG_WATCHDOG undefined, Linux can start just fine. As far as I can tell, there are no functional differences in building U-Boot with or without CONFIG_WATCHDOG enabled when the functions above are stubs and do absolutely nothing at all. If I build U-Boot with debug, what I see is as follows: ## Transferring control to Linux (at address 40020000) ... BIV ...and then the board is dead. I occasionally see something like the following from U-Boot: *** Unexpected exception *** Vector Number: 4 Format: 04 Fault Status: 0 PC: 4fdbfdc8 SR: 00002700 SP: 4fd72a64 D0: 00000004 D1: 000003f9 D2: 4fdb4202 D3: 004fa3da D4: 00000000 D5: 4fdc7c8c D6: 122c0034 D7: 4fd82f76 A0: 4033cb98 A1: 4025aa39 A2: 40020000 A3: 4fdbfdc8 A4: 00000000 A5: 4fdc5800 A6: 4fd72afb *** Please Reset Board! *** The 'BIV' is relevant because in my 2.6.29 kernel src arch/m68k/include/asm/bootinfo_mm.h, BOOTINFOV_MAGIC is defined to be 0x4249561A which is BIV^Z.

I suspect that the failure of starting Linux is caused by some mismatch in data structures (or versions there of) shared/copied between Linux and U-Boot and that this data has somehow changed when U-Boot is built with CONFIG_WATCHDOG #defined. However, I can't find any evidence of this in the U-Boot code base. The bras instruction above must be key and I suspect that this is the area causing the problem. Can anybody offer any advice / explanation of what exactly could be going on and why? I wouldn't have expected that defining CONFIG_WATCHDOG would change anything as fundamental as this. Apologies for the cross-post (U-Boot and m68k kernel dev) but I hope to get opinions/feedback/help from both communities. Any assistance very much appreciated indeed. Many thanks, -- Matt

[U-Boot] newbie questions regarding some config options.
by Christopher Harvey 22 Aug '14

22 Aug '14

As per the README file: Subscribe to u-boot mailing list; if (clueless) email("Hi, I am new to U-Boot, how do I get started?"); I'm messing around with uboot and QEMU (qemu-system-arm -M realview-pbx-a9 -kernel u-boot.bin), things are going pretty well in the sense that I'm not having too much trouble reading most of the code and creating a new board. I have some questions that I can't figure out by reading the code. What is the CONFIG_SYS_TEXT_BASE variable and how can I figure out what it should be? I randomly set it to 0x0...then tried to debug u-boot under qemu, but when stepping in the start.S file it was instantly clear that it wasn't really working because gdb said the code ran right though the _start: b reset instruction and qemu eventually crashed with the following output: qemu: fatal: Trying to execute code outside RAM or ROM at 0xfeb70cdc R00=00000000 R01=ffff0000 R02=00000000 R03=000108ac R04=ffff0000 R05=ffbedf70 R06=ffff0000 R07=00000010 R08=00001000 R09=ffff0000 R10=000108ac R11=00000000 R12=00001078 R13=ffbedf60 R14=00000960 R15=feb70cdc PSR=600001d3 -ZC- A svc32 Aborted Apart from that everything is pretty clear to me, but I want to make sure I'm getting this points right: Is the environment the set of variables that can be modified with setenv? How can I determine the "size of the environment"? Is it the number of characters including variable names? Also, is there anything special I need to do with gdb to get it to follow relocating code? thanks, -Chris

[U-Boot] [PATCH 2/2] ARM: OMAP4/5: Remove dead code against CONFIG_SYS_ENABLE_PADS_ALL
by Jassi Brar 24 Jan '14

24 Jan '14

The commit f3f98bb0 : "ARM: OMAP4/5: Do not configure non essential pads, clocks, dplls" removed the config option aimed towards moving that stuff into kernel, which renders some code unreachable. Remove that code.

[U-Boot] [PATCH 1/2] ARM: OMAP4/5: Remove dead code against CONFIG_SYS_CLOCKS_ENABLE_ALL
by Jassi Brar 24 Jan '14

24 Jan '14

The commit f3f98bb0 : "ARM: OMAP4/5: Do not configure non essential pads, clocks, dplls" removed the config option aimed towards moving that stuff into kernel, which renders some code unreachable. Remove that code. Signed-off-by: Jassi Brar <jaswinder.singh(a)linaro.org> --- Hi, The commit f3f98bb0 seems to suggest we want to move these settings into the kernel, but perhaps we should also evaluate the option of making these inits fully board specific but in u-boot?

[U-Boot] [PATCH 0/9] TS-7800 port for U-Boot
by Michael Spang 29 Jul '13

29 Jul '13

The TS-7800 is an Orion5x implementation by Technologic Systems. Albert, Wolfgang - Thanks for reviewing my patch series and sorry for the delay in updating it. Changelog: - Fixed all checkpatch errors. - Updated copyright year. - Renamed CONFIG_SKIP_LOWLEVEL_INIT to CONFIG_SKIP_CPU_INIT_CRIT and introduced new CONFIG_SKIP_LOWLEVEL_INIT that skips only lowlevel_init. - Documented machine type ID workaround in the README. - Removed "ddr" from name of orion5x_ddr_addr_decode_registers. - Allow the environment to override the MAC even if CONFIG_PRESERVE_LOCAL_MAC is set. Michael Spang (9): arm926ej-s: Invalidate instruction cache in flush_cache mvgbe: Support preserving the existing MAC address orion5x: Increase maximum bank size to 128M orion5x: Fix wrong address in orion5x_sdram_bar ARM: Rename CONFIG_SKIP_LOWLEVEL_INIT to CONFIG_SKIP_CPU_INIT_CRIT ARM: Implement CONFIG_SKIP_LOWLEVEL_INIT for arm926ej-s Add board support for TS-7800 Add NAND support for TS-7800 Add README for TS-7800 MAKEALL | 1 + Makefile | 2 +- README | 8 +- arch/arm/cpu/arm1136/start.S | 6 +- arch/arm/cpu/arm720t/start.S | 2 +- arch/arm/cpu/arm920t/at91/lowlevel_init.S | 4 +- arch/arm/cpu/arm920t/at91rm9200/lowlevel_init.S | 4 +- arch/arm/cpu/arm920t/ks8695/lowlevel_init.S | 4 +- arch/arm/cpu/arm920t/start.S | 6 +- arch/arm/cpu/arm925t/start.S | 2 +- arch/arm/cpu/arm926ejs/at91/Makefile | 2 + arch/arm/cpu/arm926ejs/davinci/Makefile | 2 + arch/arm/cpu/arm926ejs/orion5x/Makefile | 2 + arch/arm/cpu/arm926ejs/orion5x/dram.c | 6 +- arch/arm/cpu/arm926ejs/start.S | 9 +- arch/arm/cpu/arm946es/start.S | 4 +- arch/arm/cpu/arm_intcm/start.S | 4 +- arch/arm/cpu/armv7/start.S | 2 +- arch/arm/cpu/lh7a40x/start.S | 2 +- arch/arm/cpu/s3c44b0/start.S | 2 +- arch/arm/cpu/sa1100/start.S | 2 +- arch/arm/include/asm/arch-orion5x/cpu.h | 2 +- arch/arm/include/asm/arch-orion5x/orion5x.h | 3 +- arch/arm/lib/cache.c | 2 + board/ns9750dev/lowlevel_init.S | 6 +- board/technologic/ts7800/Makefile | 46 ++++++ board/technologic/ts7800/ts7800.c | 36 +++++ boards.cfg | 1 + doc/README.ts7800 | 84 ++++++++++ drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/ts7800_nand.c | 68 ++++++++ drivers/net/mvgbe.c | 20 +++ include/common.h | 2 +- include/configs/SMN42.h | 2 +- include/configs/a320evb.h | 2 +- include/configs/afeb9260.h | 2 +- include/configs/armadillo.h | 2 +- include/configs/aspenite.h | 2 +- include/configs/at91cap9adk.h | 2 +- include/configs/at91rm9200dk.h | 12 +- include/configs/at91rm9200ek.h | 6 +- include/configs/at91sam9260ek.h | 2 +- include/configs/at91sam9261ek.h | 2 +- include/configs/at91sam9263ek.h | 4 +- include/configs/at91sam9m10g45ek.h | 2 +- include/configs/at91sam9rlek.h | 2 +- include/configs/cmc_pu2.h | 4 +- include/configs/colibri_pxa270.h | 2 +- include/configs/cpuat91.h | 6 +- include/configs/csb637.h | 4 +- include/configs/da830evm.h | 2 +- include/configs/da850evm.h | 2 +- include/configs/davinci_dm355evm.h | 2 +- include/configs/davinci_dm355leopard.h | 2 +- include/configs/davinci_dm365evm.h | 2 +- include/configs/davinci_dm6467evm.h | 2 +- include/configs/davinci_dvevm.h | 6 +- include/configs/davinci_schmoogie.h | 2 +- include/configs/davinci_sffsdr.h | 2 +- include/configs/davinci_sonata.h | 6 +- include/configs/dkb.h | 2 +- include/configs/dnp1110.h | 2 +- include/configs/dockstar.h | 2 +- include/configs/ea20.h | 2 +- include/configs/evb4510.h | 2 +- include/configs/gcplus.h | 4 +- include/configs/guruplug.h | 2 +- include/configs/hawkboard.h | 2 +- include/configs/integratorap.h | 2 +- include/configs/integratorcp.h | 6 +- include/configs/kb9202.h | 2 +- include/configs/km_arm.h | 2 +- include/configs/lpc2292sodimm.h | 2 +- include/configs/meesc.h | 2 +- include/configs/mp2usb.h | 4 +- include/configs/mv88f6281gtw_ge.h | 2 +- include/configs/mx31pdk.h | 2 +- include/configs/nhk8815.h | 2 +- include/configs/openrd_base.h | 2 +- include/configs/otc570.h | 2 +- include/configs/pm9261.h | 2 +- include/configs/pm9263.h | 2 +- include/configs/pm9g45.h | 2 +- include/configs/pxa255_idp.h | 2 +- include/configs/rd6281a.h | 2 +- include/configs/sbc2410x.h | 2 +- include/configs/sbc35_a9g20.h | 2 +- include/configs/shannon.h | 2 +- include/configs/sheevaplug.h | 2 +- include/configs/tegra2-common.h | 2 +- include/configs/tny_a9260.h | 2 +- include/configs/top9000.h | 2 +- include/configs/ts7800.h | 193 +++++++++++++++++++++++ include/configs/tx25.h | 2 +- include/configs/zipitz2.h | 2 +- 95 files changed, 585 insertions(+), 117 deletions(-) create mode 100644 board/technologic/ts7800/Makefile create mode 100644 board/technologic/ts7800/ts7800.c create mode 100644 doc/README.ts7800 create mode 100644 drivers/mtd/nand/ts7800_nand.c create mode 100644 include/configs/ts7800.h -- 1.7.2.3

I've been working with Xiangfu past six months to polish v6 patches. We have addressed all comments from Wolfgang and Scott so far, drop nand_spl and USB_boot functions to make the initial bring-up minimum and simple. I think the patchset is now in good shape, so will merge and make a pull-request during this merge window. Please give it a final review and if something to fix, please let us know. Scott and Wolfgang, I know NAND land changes should go through Scott's tree, but the NAND driver is part of the initial support. May I take it through MIPS tree? Hope it's Ok with you. Changes since v6 patchset are described in each patch. Shinya --- 8< --- Boilerplate from Xiangfu Liu: those patches are for add xburst jz4740 base file and Ben NanoNote (codename qi_lb60) to U-Boot some info about xburst jz4740: the xburst jz4740 is recently added to linux 2.6.36 and it's support the device Ben NanoNote out of box, this xburst jz4740 cpu have one feature is Boot From USB, there is a small rom in jz4740, but LOW some PIN, the cpu will boot to this small rom, then init cpu and USB module, then we can send 8KB bin file to the cpu by USB(by using 'xbboot' or 'usbboot'[1]). which means if your bootloader is borken,(the first few KBs in NAND) you can always boot the device from usb, then reflash the nand. in OpenMoko FreeRunner, there are NOR and NAND. when people broken the nand bootloader, it's must boot from NOR, reflash the bootloader back when people broken the NAND and NOR, he(she) must reflash by using JTAG but in Ben NanoNote, we just need boot from usb. flash the nand again :) BTW:there are a lot of PMP, Audio device in China use the Xburst cpu, but I think they are all base on u-boot 1.1.6. by working on Ben NanoNote (http://en.qi-hardware.com) one year, we try to update the u-boot to last version and send it to upstream. :) for more info about Ingenic Xburst JZ4740 http://www.ingenic.cn/eng/default.aspx http://www.linux-mips.org/wiki/Ingenic Xiangfu Liu (3): MIPS: Ingenic XBurst Jz4740 processor support MIPS: Jz4740: Add NAND driver MIPS: Jz4740: Add qi_lb60 board support MAINTAINERS | 4 + MAKEALL | 4 +- README | 1 + arch/mips/cpu/xburst/Makefile | 49 ++ arch/mips/cpu/xburst/config.mk | 24 + arch/mips/cpu/xburst/cpu.c | 152 +++++ arch/mips/cpu/xburst/jz4740.c | 248 ++++++++ arch/mips/cpu/xburst/jz_serial.c | 114 ++++ arch/mips/cpu/xburst/start.S | 171 ++++++ arch/mips/cpu/xburst/timer.c | 162 +++++ arch/mips/include/asm/global_data.h | 11 + arch/mips/include/asm/jz4740.h | 1150 +++++++++++++++++++++++++++++++++++ board/qi/qi_lb60/Makefile | 45 ++ board/qi/qi_lb60/config.mk | 31 + board/qi/qi_lb60/qi_lb60.c | 104 ++++ board/qi/qi_lb60/u-boot.lds | 61 ++ boards.cfg | 1 + drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/jz4740_nand.c | 261 ++++++++ include/configs/qi_lb60.h | 211 +++++++ 20 files changed, 2804 insertions(+), 1 deletions(-) create mode 100644 arch/mips/cpu/xburst/Makefile create mode 100644 arch/mips/cpu/xburst/config.mk create mode 100644 arch/mips/cpu/xburst/cpu.c create mode 100644 arch/mips/cpu/xburst/jz4740.c create mode 100644 arch/mips/cpu/xburst/jz_serial.c create mode 100644 arch/mips/cpu/xburst/start.S create mode 100644 arch/mips/cpu/xburst/timer.c create mode 100644 arch/mips/include/asm/jz4740.h create mode 100644 board/qi/qi_lb60/Makefile create mode 100644 board/qi/qi_lb60/config.mk create mode 100644 board/qi/qi_lb60/qi_lb60.c create mode 100644 board/qi/qi_lb60/u-boot.lds create mode 100644 drivers/mtd/nand/jz4740_nand.c create mode 100644 include/configs/qi_lb60.h
