Extracting a copy of SPI NOR flash contents using micro SD card and u-boot - hmuller - 09-21-2020 This is a bonus. Using the previous post: https://forum.pine64.org/showthread.php?tid=11567 A 32M sized micro SD card image should be sufficient to extract a full copy of SPI NOR flash contents. I performed the following successfully using a 64M sized image to extract a full copy of SPI NOR flash from u-boot prompt with micro SD card inserted: Code: => sf probe 1:0 This will save the contents of your flash to the micro SD card, the file will be named 'spi_full.img'. You can then view the image using your favorite tool. As an example: Code: $ xxd /path/to/spi_full.img | less |
