Flashing and Erasing the SPITraditionally, booting Linux on the ROCK64 required an eMMC or microSD card, however it is now possible to boot without those, assuming the SPI memory has been flashed. The ROCK64 contains an onboard 128Mbit SPI flash memory, which can be flashed with U-Boot in order to provide additional boot options:USB2 / USB3 drivePXEmicroSDeMMC1. Write the U-Boot imageDownload the latest u-boot-flash-spi.img.xz imageWrite it to a microSD card using dd or Etcher bs=1M"># From Linux or macOSxz -k -d -c -v -T 3 u-boot-flash-spi.img.xz | dd of=/dev/sdcard> bs=1MMake sure you write to the correction location, it will destroy all data.2.

Fix for SPI Flashing failuresIf, for any reason, your SPI flashing gets interrupted during its process, you may experience a "frozen" device.To solve this, on the Rock64 follow these instructions:Go to this guide to create a new ayufan bootable Linux SD cardOr, in short, download the latest ayufan Linux distribution from here, and use etcher to flash you SD cardInsert the SD card to the Rock64.Connect other peripherals such as network to later control your device, such as via ssh.ayufan’s Linux distro will connect to the network and you will be able to ssh to the device.Ground the SPI Clock (SPI_CLK_M2) on the Pi-2 Bus GPIO pins on the rock64Pin 23 is SPI_CLK_M2Pin 25 is GNDPin layout of the rock64 can be found hereOther Rock64 documents can be found hereTurn on the device and release the grounding of the SPI Clock 2-3 seconds after the device was turned on.NOTE: This is a critical stepIf not done correctly you will not be able to flash the deviceIf unsuccessful turn of the device and try again.login and go to the folder with the flashing scriptscd /usr/local/sbinsudo ./rock64_erase_spi_flash.sh or sudo ./rock64_write_spi_flash.shType "YES" to flash the deviceIf the flashing failes with an error loader partition on MTD is not found repeat step 5.Your device should now be able to boot without holding the SPI Clock.

Advertised and is surprisingly breathable in testing up to about 65 degrees Fahrenheit.It has also kept feet warm throughout winter. On one particular winter hike, we pushed these boots to the limits in terms of distance, elements, and trail: a 10-mile winter hike over a frozen trail, packed snow, iced-over stream crossings, and more. We even tested the boots with microspikes to see how they fit and feel together.These were great for mid-length to longer day hikes or overnight summer backpacking trips if you don’t mind the weight. They should handle rough trails with aplomb. They’ll find their limit at heavy off-trail use; these aren’t cut out for multiday winter camping, heavy off-trail bushwhacking, or mountaineering.My favorite aspect of this boot would have to be the traction. The 5mm lugs and grippy outsole definitely reinforces this boot’s sturdy feel and make it a great choice for looser or more technical trails.REI’s two hiking boot models have vastly different designs and purposes, but if I had to pick, the Traverse boot took the cake for me. They are comfortable, really waterproof, budget-friendly, and a damn good pair of boots overall.Pros:Great waterproofingFirm fit and great tractionStrong ankle supportI received lots of compliments on the colorCons:A little stiff, could have more flexThe Traverse (and Flash) boots come in the following sizes: men’s 8-14 and women’s 6-11.Shop Women’sShop Men’sREI Flash Hiking Boot Review" data-src=" data-srcset=" 2400w, 300w, 700w, 768w, 1536w, 2048w, 1200w, 600w, 1240w, 620w, 588w, 294w, 382w, 191w, 120w, 240w, 217w, 446w, 223w, 1220w, 610w, 1676w, 838w, 900w, 450w, 1940w, 1880w, 133w, 267w">Testing the REI Flash hiking boot; photo by Adam RuggieroFor extra breathability on summer hikes and a softer, more shoe-like feel, REI has its Flash Hiking Boot ($130) model. Not unlike the Co-op’s Flash line of packs, which offer airier, less cumbersome options compared to Traverse packs, these boots maintain some key features but strip away the excess.REI Flash Boot SpecsMaterials: Recycled knit upper, 75% recycled poly waterproof HydroWall membrane, 10% Bloom algae midsole, lightweight shank, recycled grip outsoleLugs: 4 mmWeight: 30 oz.

The upper uses REI’s FirmaKnit construction (the same upper material as in the Traverse). As expected, the knit construction feels more air-permeable and offers greater fore and lateral flex than the mostly waterproof upper on the

Measures in the latest macOS.11) To rebuild Time Machine disks in macOS 10.14 Mojave and later, DiskWarrior must be given “Full Disk Access” from within System Preferences. Using DiskWarrior Recovery Maker 1.4.What you need to know1) DiskWarrior Recovery Maker 1.4 is compatible with macOS 10.14 Mojave and macOS 10.15 Catalina. You will need DiskWarrior 5.3 to run DiskWarrior from a recovery flash drive created while running macOS 10.14 Mojave or macOS 10.15 Catalina. Creating a 10.14 or 10.15 recovery flash drive will not allow DiskWarrior to rebuild APFS (Apple File System) disks.2) An extra step is needed to create a DiskWarrior startup recovery flash drive on the latest Mac that are equipped with Secure Boot via Apple’s T2 Security Chip. By default, Secure Boot does not allow starting up from an external disk such as a DiskWarrior recovery flash drive. Also by default, Secure Boot prevents the creation of a macOS startup disk except for those created using Apple's Installer.To create and use a DiskWarrior Recovery disk for Macs with Secure Boot, it will be necessary to change the default Secure Boot and External Boot settings using the Startup Security Utility. The Secure Boot setting will need to be changed to Medium Security or No Security. Alsoft recommends Medium Security. Additionally, the External Boot setting will need to be changed to Allow booting from external media. 1) DiskWarrior 5.3 is compatible with macOS 10.13 High Sierra or later when rebuilding external Mac OS Extended disks.2) Your external drives (including Time

This is because running in this mode, Ubuntu uses available RAM in place of Swap and Hard Disk space. This option also contains the install files needed to install Ubuntu directly to your desktop if you should so desire.Option 2: Boot Ubuntu as a Live CD with Persistence from a USB Flash Drive This option will install Ubuntu Linux onto your flash drive with an area for persistent storage. You will be able to restart the computer, boot back into the Linux environment and all settings or changes made previously will persist.NOTE: This option is particularly hard on Flash Memory, as there can be quite a bit of reading and writing to the Flash Memory.What you will need:Running Windows XP/Vista/7Fat32 Formatted USB 2.0 Flash Drive, at least 2GBPC with a Bios that can boot from USBNow with all of the necessary components in place, we can begin to setup our Ubuntu Live USB Drive.1.
