Even if this partition is bad and CRC32 passes, only the xo_correction is used and itself will fail gracefully if wrong values provided. The U-Boot environment sections are protected with a CRC32, so if something has become corrupt, it will be skipped. Therefore, the flash must be unlocked if you want to overwrite this partition. Note that this section of flash is protected. If you need to clear it, just make a file that starts with 0xFF, and write it. Here we can see this is blank (all 0xFF), meaning that no custom calibration data is currently used on this device. uboot-extra-env.dfuĠ0000000 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |.|
This will upload things from the device to your PC. uboot-extra-env.dfuĭetermining device status: state = dfuIDLE, status = 0 A good idea is just to check it: sudo dfu-util -a uboot-extra-env.dfu -U. This is where things like factory calibration and ppm offset are stored. When the system boots, it follows this basic process: dfu-utils is known to work better the 2nd time. Just don't type in the sudo that is necessary on Linux. For example:Ĭ:\> cd “c:\Program Files\Analog Devices\PlutoSDR-M2K”Ĭ:\Program Files\Analog Devices\PlutoSDR-M2K> dfu-util.exe -lĬopyright 2005-2009 Weston Schmidt, Harald Welte and OpenMoko Inc.Ĭopyright 2010-2016 Tormod Volden and Stefan Schmidt It's easy to go to this directory, and run things from there.

When you installed the Pluto or M2k Windows Drivers, it put the dfu-utils on your hard drive (that's why you accepted the GPL when you installed the Windows license). Although these examples are on a Linux machine, on Windows, it is similar.
