[U-Boot] [PATCH v5] MPC8360EMDS: 512MB DDR and 33.33MHz oscillator support
by Chang-Ming.Huang＠freescale.com 03 Nov '11

03 Nov '11

From: Jerry Huang <Chang-Ming.Huang(a)freescale.com> The new MPC8360EMDS board changes the oscillator to 33.33MHz in order to support QE 500MHZ and this new board supports 512MB DDR since 2008, but the u-boot only supports 256MB DDR and 66.6MHz oscillator on top tree, For 512MB DDR: BAT0 is used for the first 256MB memory, BAT4 is used for the second 256MB memory and the address space of SDRAM follows the DDR, so if the size of DDR is 256MB, the BAT4 will be used for SDRAM and if the size of DDR is 512MB, the BAT4 will be used for the second 256MB memory and there is no BAT for SDRAM. Therefore, if the size of DDR is 512MB, this patch will use BAT6 for SDRAM and BAT5 will be used for PCI MEM to replace the BAT6 after the codes relocates to the DDR.

[U-Boot] malloc issue while migrating from 2010.03 to 2011.06 U-boot
by Vinay Hegde 03 Nov '11

03 Nov '11

Hi All, I am trying to port one existing platform (which uses 2010.03 U-Boot) to 2011.06 U-Boot. I have an issue while env_relocate. The malloc fails in himport_r function. I tried multiple things and quite not sure whats going on. From the boot log (till env_relocate) things seem to be fine. I have also tried changing the CONFIG_SYS_MALLOC_LEN to (1024 * 1024), that did not make any difference to the issue. Here is the log: >>>> U-Boot 2011.06 (Nov 02 2011 - 13:42:27) CPU: 8548, Version: 2.1, (0x80310021) Core: E500, Version: 2.2, (0x80210022) Clock Configuration: CPU0:1500 MHz, CCB:500 MHz, DDR:250 MHz (500 MT/s data rate), LBC:31.250 MHz L1: D-cache 32 kB enabled I-cache 32 kB enabled Board: E45-40F 10.12 I2C: ready DRAM: Initializing Configuring DDR for 500 MT/s data rate DDR: 1 GiB Top of RAM usable for U-Boot at: 40000000 Reserving 584k for U-Boot at: 3ff60000 Reserving 1032k for malloc() at: 3fe5e000 Reserving 80 Bytes for Board Info at: 3fe5dfb0 Reserving 124 Bytes for Global Data at: 3fe5df34 Stack Pointer at: 3fe5df18 New Stack Pointer is: 3fe5df18 Now running in RAM - U-Boot at: 3ff60000 Flash: 8 MiB L2: 512 KB enabled himport_r: can't malloc 8188 bytes ERROR: Cannot import environment: errno = 12 at env_common.c:238/env_import() *** Warning - import failed, using default environment himport_r: can't malloc 223 bytes ERROR: Environment import failed: errno = 12 at env_common.c:196/set_default_env() Bad trap at PC: 3ff62584, SR: 21200, vector=d00 -----> this trap is when trying to access bd->bi_enetaddr.

[U-Boot] u-boot master on a pandaboard won't boot
by Lalancette, Christopher 03 Nov '11

03 Nov '11

Hello, I've recently been playing around with u-boot on a pandaboard Rev A1. The rest of my environment is an MLO built from x-loader git hash c4289f1bee035dea41536c5ba5e1bc36c7d493c4, and booting an ubuntu 11.04 kernel 2.6.38-1208-omap4. Up until tag v2011.06, u-boot works flawlessly (as far as I've tested) on this combination. However, if I take any u-boot release after that, including v2011.09 and u-boot git head, u-boot hangs very early on: Texas Instruments X-Loader 1.5.1 (Nov 2 2011 - 08:55:25) Reading boot sector Loading u-boot.bin from mmc And the status LEDs blink rapidly. I bisected the problem down to commit bcae72116257201d7288cb8c525a29aea4875b95; prior to that commit, I can successfully[1] boot u-boot on the pandaboard, but after that I cannot. I'm going to poke at it a bit more, but does anyone have any ideas of what is going on here? --- Chris Lalancette [1] Well, I can at least get beyond "Loading u-boot.bin from mmc" and boot the kernel and userland. For some reason with this setup I can't get ethernet to work, but one problem at a time.

[U-Boot] [PATCH 0/5] mmc: Tegra2: DMA related fixes
by Anton Staaf 03 Nov '11

03 Nov '11

The first two patches in this set are basic bug fixes for the Tegra2 MMC driver. The third patch is cleanup. The fourth patch adds some cache management utility functions to the generic MMC code. And the final patch adds bounce buffer management, cache flusing, and cache invalidation to the Tegra2 MMC driver. This bounce buffer allows the driver to function correctly even when faced with incorrectly aligned buffers. My other patch sets attempt to fix as many unaligned buffers as I could find. But there are likely more to deal with and it is preferable that the MMC driver continue to function in the face of unaligned buffers, even if it slows down due to memcpy overhead. An alternative to the fifth patch would be to attempt to add this bounce buffer management to the generic MMC layer itself. This would benefit all architectures, but would require more testing and work. It seems better to enable it here first and then move it to the generic code. Once a generic solution is in place this code can be reverted. It might even make sense to put the bounce buffer code all the way up in the block interface layer. But my hope is that we can hash that all out independently of this patch. :) Anton Staaf (5): mmc: Tegra2: Support DMA restarts at buffer boundaries mmc: Tegra2: Add data transfer completion timeout mmc: Tegra2: Factor out mmc_wait_inhibit functionality mmc: Create dcache flush and invalidate convenience methods mmc: Tegra2: Enable dcache support by bouncing unaligned requests. drivers/mmc/mmc.c | 23 +++++ drivers/mmc/tegra2_mmc.c | 202 +++++++++++++++++++++++++++++++++++++++++----- drivers/mmc/tegra2_mmc.h | 14 +++ include/mmc.h | 10 +++ 4 files changed, 227 insertions(+), 22 deletions(-) -- 1.7.3.1
