[U-Boot] [PATCH] ubifs: Correct dereferencing of files-after-symlinks
by Simon Kagstrom 28 Sep '09

28 Sep '09

Files in directories which are symlinked to were not dereferenced correctly in last commit. E.g., with a symlink /boot/lnk -> /boot/real_dir loading /boot/lnk/uImage will fail. This patch fixes that by simply seeing to it that the target base directory has a slash after it.

[U-Boot] EHCI driver problem
by Jussi Eronen 28 Sep '09

28 Sep '09

Hi, I am working on a propietary board, which has MPC8270 cpu (big endian mode) and NEC uPD720101 USB controller, with devices connected to ports 1-4. OHCI and EHCI work fine with Linux kernel and OHCI works also in u-boot. I recall from some discussion that u-boot can only use one OHCI controller at a time and EHCI could be used to overcome this limitation. I tried to config u-boot for OHCI#1 and #2 and the both work as expected using ports 1&3 or 2&4. To get simulateous access to all ports, I wanted to get EHCI to work with u-boot. Problem is, that driver doesn't recognice any devices. My config for EHCI is #define CONFIG_LEGACY_USB_INIT_SEQ 1 #define CONFIG_SYS_USB_HOST #define CONFIG_PCI_EHCI_DEVICE 0 #define CONFIG_USB_EHCI #define CONFIG_USB_EHCI_PCI 1 #define CONFIG_EHCI_MMIO_BIG_ENDIAN 1 #define CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS 10 #define CONFIG_PCI_EHCI_DEVNO 0 #define CONFIG_EHCI_HCD_INIT_AFTER_RESET 1 When I run 'usb start', this is what I get (added some extra debugging messages): usb start (Re)start USB... USB: Register 2395 NbrPorts 5 USB EHCI 1.00 scanning bus for devices... New Device 0 .... So init founds the chip and tries to use it. However, resetting of each port fails (or that was at least how I interpreted later messages). Later for each port reset is tried 5 times usb_control_msg: request: 0x3, requesttype: 0x23, value 0x4 index 0x1 length 0x0 ehci_submit_root, rootdev=1, req=3 (0x3), type=35 (0x23), value=4, index=1 Len is 0 (00000000 0) usb_control_msg: request: 0x0, requesttype: 0xA3, value 0x0 index 0x1 length 0x4 ehci_submit_root, rootdev=1, req=0 (0x0), type=163 (0xa3), value=0, index=1 portstatus 511, change 10, 480 Mb/s STAT_C_CONNECTION = 0 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 0 Cannot enable port 1 after 5 retries, disabling port. Maybe the USB cable is bad? cannot reset port 1!? --Jussi

[U-Boot] [PATCH] [RFC]mpc83xx: Remove need for -ffixed-r14
by Joakim Tjernlund 28 Sep '09

28 Sep '09

Seems to me that the only need for -ffixed-r14 is to find transfer_to_handler from whithin an IRQ. Add transfer_to_handler to the trap relocation so the need for a GOT access in IRQ context goes away. NOTE: This will break other PPC archs until their start.S is updated accordingly.

[U-Boot] [PATCH] ppc4xx: Convert PPC4xx SDRAM defines from lower case to upper case
by Stefan Roese 28 Sep '09

28 Sep '09

The latest PPC4xx register cleanup patch missed some SDRAM defines. This patch now changes lower case UIC defines to upper case. Also some names are changed to match the naming in the IBM/AMCC users manuals (e.g. mem_mcopt1 -> SDRAM0_CFG).

[U-Boot] Adding new U-Boot Command.
by Tuma 28 Sep '09

28 Sep '09

Hi, All! Help me please in writting new U-Boot commands. What should I do? I should write new file in "/common", something like cmd_****, am I right? So where can I read about cmd_-file structure and how should new commands be added? And how can I add my new file to U-Boot binary? -- Software Developer General Satellite Corp.

[U-Boot] ref: pxa lcd color problem...
by Paul Wang 28 Sep '09

28 Sep '09

Hi, All, I have a problem when using the U-Boot 1.3.3 on a Pxa270 dev board (Phycore_pxa270). The board has a SHARP_LQ084V1DG21 LCD that is set as a 16 bpp panel. After some modifications, I can display a 16 bpp bitmap on the screen. The problem is that the color is not correct. The problem is verified by just drawing 16 bpp RGB color stripes on the screen. The LCD hardware interface is 5:6:5 RGB. Sp, the data for the color stripes are RED: 0xF800; GREEN: 0x07E0; BLUE: 0x001F etc. I checked all LCD GPIO settings, LCD register settings several times. They seem correct. I wonder did anyone have the same problem on pxa270 before, on which version of U-Boot? Thanks for any help or information. Paul Wang.

[U-Boot] [PATCH v3] OMAP3 MMC: Fix warning dereferencing type-punned pointer
by Dirk Behme 28 Sep '09

28 Sep '09

Fix warning dereferencing type-punned pointer will break strict-aliasing rules Signed-off-by: Dirk Behme <dirk.behme(a)googlemail.com> CC: Steve Sakoman <sakoman(a)gmail.com> CC: Tom Rix <Tom.Rix(a)windriver.com> --- Changes in v3: Move union type definition to architecture mmc.h as proposed by Tom. Changes in v2: Union elements mmc_resp_r3 and mmc_resp_r6 are no pointers. v1 of this patch breaks MMC handling. Please revert v1 in u-boot-ti http://git.denx.de/?p=u-boot/u-boot-ti.git;a=commit;h=eb19df366587c887a406d… and use this one. Thanks to Steve Sakoman for reporting this!
