SPI images MMC images

download miZy images from https://github.com/hyphop/miZy/releases

we have SPI and MMC image types

SPI

write to SPI flash only

*.8M.bin - spi image *.16M.bin - spi image

example

wget https://github.com/hyphop/miZy/releases/download/mpd/orange-pi-h2-miZy-musicbox-mpd.SPI.16M.bin.gz
gzip -d *.bin.gz

MMC image begin from extra 8192 bytes header - we can use this space for MBR or partition table

convert MMC to SPI image

skip header example

dd bs=8192 skip=1 count=1 < *.MMC.*bin | hd | head
1+0 records in
1+0 records out
8192 bytes (8.2 kB, 8.0 KiB) copied, 8.6447e-05 s, 94.8 MB/s
