I've opened a PR with coremark component and example: https://github.com/espressif/idf-extra- ... s/pull/216.bananymous wrote: Hi. We are trying to measure coremark on esp32-c3. We have got score of 386 with -O3 which significantly less than the one marked in the datasheet (407.22). Does anyone know which parameters are selected in menuconfig in the datasheet benchmark? Is there a github repo with the settings of the datasheet's measurement?
