Hi, I've updated barebox for our custom platform from v2015.06.0 to v2019.12.0. With the new version I have noticed a much worse write performance onto the onboard eMMC.
With v2015.06.0 the indicated progress of the copy command is very smooth. Calling "cp -v /dev/zero /dev/mmc3.root" takes about 80 seconds for 256MB. But with v2019.12.0 the progress is very bumpy and the copy takes about 280 seconds. I've tracked this down to this commit which destroys the performance: "block: Adjust cache sizes" (b6fef20c1215c6ef0004f6af4a9c4b77af51dc43) Regards Hubert _______________________________________________ barebox mailing list [email protected] http://lists.infradead.org/mailman/listinfo/barebox
