Hi all, I have questions regarding ramdisk built based on the core-image-minimal (poky sumo tag sumo-19.0.1 and meta-freescale sumo branch is used):
1. How can I configure the available memory size to use for rootfs (either a larger fixed size or growing dynamically)? The rootfs available size of the default Yocto build seems to be capped at around 24MB. See df and mount outputs below: # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 23795 21071 1496 93% / devtmpfs 480492 0 480492 0% /dev tmpfs 516520 32 516488 0% /run tmpfs 516520 24 516496 0% /var/volatile # mount /dev/root on / type ext4 (rw,relatime,block_validity,delalloc,barrier,user_xattr) ... 1. This may not be relevant to the problem, but good to know: My understanding is that the Yocto built ramdisk based on core-image-minimal uses initrd, not initramfs. Is this correct? How can I tell if a system uses initrd or initramfs? Any help is greatly appreciated. Thank you in advance.
