[U-Boot] [PATCH v4] palmtreo680: add utility that writes u-boot to flash
by Mike Dunn 18 Apr '13

18 Apr '13

This adds a userspace linux utility that writes the u-boot image to an mtd partition on the docg4 nand flash. A special utility is required to do this because u-boot is partially loaded by an initial program loader (IPL) that is permanently programmed to the boot region of the flash. This IPL expects the image to be written in a unique format. The characteristics of this format can be summarized as follows: - Flash blocks to be loaded must have a magic number in the oob bytes of the first page of the block. - Each page must be written redundantly in the subsequent page. - The integrated flash controller's "reliable mode" is used, requiring that alternate 2k regions (4 pages) are skipped when writing. For these reasons, a u-boot image can not be written using nandwrite from mtd-utils. Signed-off-by: Mike Dunn <mikedunn(a)newsguy.com> --- Changelog: v4: - use return instead of exit - use calloc() instead of malloc() - remove call to read() from within while loop test v3: new patch; split off from patch 7 in v2 of patchset I was wrong, Marek... the read() will return EOF while writing the last block, unless the size of the image is such that it fills the last block. Otherwise, the last block is only partially written, and stops at EOF. This is fine. tools/palmtreo680/flash_u-boot.c | 168 ++++++++++++++++++++++++++++++++++++++ 1 files changed, 168 insertions(+), 0 deletions(-) create mode 100644 tools/palmtreo680/flash_u-boot.c diff --git a/tools/palmtreo680/flash_u-boot.c b/tools/palmtreo680/flash_u-boot.c new file mode 100644 index 0000000..8f8dadf --- /dev/null +++ b/tools/palmtreo680/flash_u-boot.c @@ -0,0 +1,168 @@ +/* + * Copyright (C) 2013 Mike Dunn <mikedunn(a)newsguy.com> + * + * This file is released under the terms of GPL v2 and any later version. + * See the file COPYING in the root directory of the source tree for details. + * + * + * This is a userspace Linux utility that, when run on the Treo 680, will + * program u-boot to flash.

[U-Boot] phy ic isn't reset

Hi: I work on one board based on at9g25evk board now. I find one issue that phy IC isn't reset, so network can't work. Only the different crystal with evk board is connected to PHY IC. I copy the phy-reset part of at9260 to at9g25. It can work now. Please the maintainer of at9gx5 check this. The modification I do is as below: + +#ifdef CONFIG_MACB +int at91sam9x5ek_macb_hw_init(void) +{ + struct at91_pmc *pmc = (struct at91_pmc *)ATMEL_BASE_PMC; + struct at91_port *pioa = (struct at91_port *)ATMEL_BASE_PIOA; + struct at91_rstc *rstc = (struct at91_rstc *)ATMEL_BASE_RSTC; + unsigned long erstl; + + /* Enable EMAC clock */ + writel(1 << ATMEL_ID_EMAC0, &pmc->pcer); + + erstl = readl(&rstc->mr) & AT91_RSTC_MR_ERSTL_MASK; + + /* Need to reset PHY -> 500ms reset */ + writel(AT91_RSTC_KEY | AT91_RSTC_MR_ERSTL(13) | + AT91_RSTC_MR_URSTEN, &rstc->mr); + + writel(AT91_RSTC_KEY | AT91_RSTC_CR_EXTRST, &rstc->cr); + + /* Wait for end hardware reset */ + while (!(readl(&rstc->sr) & AT91_RSTC_SR_NRSTL)) + ; + + /* Restore NRST value */ + writel(AT91_RSTC_KEY | erstl | AT91_RSTC_MR_URSTEN, + &rstc->mr); + + at91_macb_hw_init(); +} +#endif Best Regards, Alex

[U-Boot] USB Device Identification -- non-removable USB NAND flash
by Curt Brune 18 Apr '13

18 Apr '13

Hi - Looking for suggestions on how to identify a particular USB mass storage device on my platform. My platform has a P2020 SoC. The SoC USB controller is connected to an on board USB hub. The hub has 3 connections as follows: +---------+ | |--->[USB flash controller, fronting a 2GB NAND flash] | USB Hub |--->[front panel USB connector] | |--->[front panel USB connector] +---------+ My uImage is stored on the NAND in a raw partition. I have been using the usbboot command just fine. Something like this: uboot> usbboot $loadaddr 0:0 && bootm $loadaddr That boots from storage device 0, partition 0. That works great. The problem is when I *also* have a USB memory stick plugged into one of the front panel ports. In that case my boot device no longer shows up as device "0", but rather "1". I'm guessing this problem is not unique. Is there a way to "fix" the device number for the non-removable flash to always be 0? Alternatively is there a way to figure out at run time (in a script) what device corresponds to my internal flash? I started hacking on common/usb.c and I see how I can make it work, but that solution seemed wrong. There's got to be a better way. Any suggestions are much appreciated. Cheers, Curt
