Package: u-boot-tools Version: 2016.01+dfsg1-1 Severity: wishlist I believe the following to be true based on experiments with my two sheevaplugs:
If your Sheevaplug has a u-boot version prior to 2014.10+dfsg1-5, including any of the original "Marvell" versions, the environment is located at 0x60000 and this should be reflected in the "Device offset" field in the /etc/fw_env.config file. If your Sheevaplug has a u-boot version of 2014.10+dfsg1-5, e.g. if you upgraded u-boot while running Debian Jessie, or 2016.01+dfsg1-1 or later from Debian Stretch or later, the environment is located at 0x80000 and this should, in turn, be reflected in the "Device offset" field in the /etc/fw_env.config file. I theorize that the reason for this is that versions of the u-boot.kwb binary prior to 2014.10 were shorter than 0x60000 (three erase pages in the MTD flash), so it made sense to locate the environment at the beginning of the fourth erase page, 0x60000. But with the 2014.10 version and later, the u-boot.kwb binary had grown and now encroached upon part of the fourth erase page. This meant that the environment had to move up one erase page to 0x80000. If this is correct, it needs to be reflected in /usr/share/doc/u-boot-tools/examples/sheevaplug.config so that users can configure /etc/fw_env.config correctly for their particular machines. If a similar analysis applies to other arm devices that use u-boot (I don't know whether it does), then it might be appropriate to put it in a README file in the /usr/share/doc/u-boot-tools/examples directory. A pointer to that README should go in /usr/share/doc/u-boot-tools/examples/*.config, as appropriate for affected devices.
