Took me a while to figure out why my board took 90 seconds to boot suddenly.
The issue turned out to be the ext4 partition created by wic. On a "wic" created ext4 disk, this is what u-boot does: ZynqMP> load mmc 0:2 0x100000 /lib/firmware/fpga.bin 19311092 bytes read in 85529 ms (219.7 KiB/s) Now if I boot the board rename and copy that file onto itself, then it's suddenly normal again when I reboot the board: ZynqMP> load mmc 0:2 0x100000 /lib/firmware/fpga.bin 19311092 bytes read in 1426 ms (12.9 MiB/s) I checked with other files, and it turns out that ANY big file written by wic will read very slow (at 200k/s) but if I make a copy from a running system, it suddenly reads fast. I'm not knowledgeable on ext4, so any ideas what's being passed onto the image creation tool that causes this? -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
