Re: [U-Boot] [PATCH v5] palmtreo680: add utility that writes u-boot to flash
Dear Mike Dunn, 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. I fixed the calloc() semantics and applied, thanks. Please repost whatever is still missing in u-boot-pxa/master and I'll then roll pullRQ for mainline. Best regards, Marek Vasut ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Only arm: bootm: call udc_disable() before booting linux is not in your tree; I think you were worried about testing on musb boards. I'll repost, but no reason to take a risk; I hope to get a patch for the Linux udc driver upstream soon.

Check that first please, I'm not sure now ;-) Yes, we went back-and-forth about it, and the latest version was v4. But I need to rework it because the spl build now fails due to a recent change to arch/arm/cpu/pxa/start.S in commit 7086e91b0e9930139e703c8f9f857b52baf2bef4 arm: relocate_code(): Use __image_copy_end for end of relocation I was using my own linker script for the spl, which does not define the __image_copy_end symbol that is now referenced in start.S. I don't exactly remember why I felt the need to avoid using the script in arch/arm/cpu/u-boot-spl.lds, except that I didn't like all the sections created by the --ffunction-sections and --fdata-sections compiler flags and wanted them combined with a '*' wildcard. But I removed my linker script and the CONFIG_SPL_LDSCRIPT line from my config file and it is testing fine. So I will have to post a v5 of the patch. Thanks again Marek, Mike ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
[U-Boot] [PATCH v5] palmtreo680: add utility that writes u-boot to flash
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.

Changelog:
v5: on error, return sensible code from errno.h
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
