[U-Boot] [PATCH V2 0/3] Fix hang when loading U-Boot from SPI or NAND
by Tom Warren 20 Apr '11

20 Apr '11

This series of patches fixes a hang seen when loading U-Boot from SPI or NAND on Seaboard and Harmony due to a missing PLLX init. It also corrects a UARTD bit error in clk_rst.h, and adds rudimentary GPIO support so that the UART on Seaboard can be used by U-Boot (UARTD & SPIFLASH are muxed, and the default POR setting is for SPI access, so GPIO_PI3 has to be driven low to enable serial console I/O over UARTD). Harmony has no SPIFLASH, so the issue doesn't exist there. With these changes, I can write U-Boot to SPI on Seaboard and boot with it to the U-Boot cmd prompt. This should also apply to loading from NAND on Seaboard and Harmony - testing to follow. Changes in V2: - Change 2nd patch's description to 'Add basic GPIO definitions' - Add more descriptive comment for CPCON use in init_pllx Tom Warren (3): arm: Tegra2: Add missing PLLX init arm: Tegra2: GPIO: Add basic GPIO definitions arm: Tegra2: Move clk/mux init to board_early_init_f, add GPIO init arch/arm/cpu/armv7/tegra2/ap20.c | 29 ++++++++++++++ arch/arm/include/asm/arch-tegra2/clk_rst.h | 6 ++- arch/arm/include/asm/arch-tegra2/gpio.h | 59 ++++++++++++++++++++++++++++ arch/arm/include/asm/arch-tegra2/tegra2.h | 1 + board/nvidia/common/board.c | 32 ++++++++++----- board/nvidia/common/board.h | 4 ++ board/nvidia/harmony/Makefile | 1 + board/nvidia/harmony/harmony.c | 34 ++++++++++++++++ board/nvidia/seaboard/Makefile | 1 + board/nvidia/seaboard/seaboard.c | 52 ++++++++++++++++++++++++ 10 files changed, 206 insertions(+), 13 deletions(-) create mode 100644 arch/arm/include/asm/arch-tegra2/gpio.h create mode 100644 board/nvidia/harmony/harmony.c create mode 100644 board/nvidia/seaboard/seaboard.c -- 1.7.4.3

[U-Boot] [PATCH] QorIQ corenet_ds.h: Wrong PCIe 3 virtual address
by Trübenbach, Ralf 20 Apr '11

20 Apr '11

This patch fixes a wrong address define in corenet_ds.h (used by P4080DS.h, P3041DS.h, P5020DS.h). Since board/Freescale/corenet_ds/tlb.c does not use the CONFIG_SYS_PCIE3_MEM_VIRT define (uses CONFIG_SYS_PCIE1_MEM_VIRT with a fix offset instead) this has no effect to the functionality. But it may be important for changes in the future?

[U-Boot] TFTP - check for len == 0 before storing
by David Andrey 20 Apr '11

20 Apr '11

Hello, I had a problem with an old TFTP Server which is sending a second "last" data block with "len == 0" at end. It's clearly not RFC conform, but I still made a additional check in u-boot/tftp to avoid a wrong "filesize" value. This wrong filesize value caused some trouble by NAND operations.

[U-Boot] UEC phy not working on first try

Hi all- I am using u-boot.2010.09 on a MPC8568-based board. When trying to boot over one of the UEC network interfaces, it is not working instantly. The cable is connected from the beginning, but I have to issue a manual 'boot' command, sometimes even multiple times before the link is correct. This is the output: [----------------------------- snip -----------------------------] Net: UEC0, UEC1, UEC3 [PRIME], eTSEC0, eTSEC1 Hit any key to stop autoboot: 0 UEC: PHY is Generic MII (70431) UEC3: Full Duplex switching to rgmii 100 UEC3: Speed 100BT UEC3: Link is up UEC3: Link is down WARNING: adjusting available memory to 30000000 Wrong Image Format for bootm command ERROR: can't get kernel image! => boot UEC3: Full Duplex switching to rgmii 100 UEC3: Speed 100BT UEC3: Link is up Using UEC3 device TFTP from server 10.169.15.10; our IP address is 10.169.15.9 Filename 'uImage'.
