You can restrict it to run on a specific core by running taskset -c 4= ./tests/checkasm/checkasm ...where 4 is the number of the core you want to= run it on. It might require some testing to figure out which cores are the= big ones (A720) and which ones are the small ones (A520). The numbers on A= 520 should be bigger, as it's a slower core. We're mostly interested in the= before/after numbers on A520, but if you can time on A720 as well, that'd = be appreciated! > >=20 >=20 > Can we purchase a ARM V9 board for testing, e.g., radxa o6, orange pi 6 ?
