Thanks. I extracted it to include an init file at / (see other mail on
the thread for why) and fed the directory as initramfs source on the
kernel config.
I'm currently studying how I would write a squashfs filesystem to SPI
flash. I know how to write a file to SPI flash but the remaining is
currently a mystery to me.
By the way, I'm also doing some tests with lzma decompression on U-Boot.
I'll reply on your thread when I have some results.
