Caveat: My information could be a little out of date. We're still running on a pre-release version of RTEMS 5.0. But hopefully this points you in the right direction. In particular, I know that some work has been done to support 4kB pages, but I don't know if the entry point arm_cp15_start_setup_translation_table_and_enable_mmu_and_cache currently uses that support or not.
the 4KiB pages MMU configuration was added with this commit: commit f9648baf65ecec2cd01c96557a677ad6ecc06b11 Author: Sebastian Huber <sebastian.hu...@embedded-brains.de> Date: Mon Oct 28 10:15:28 2019 +0100 bsps/arm: Add support for small pages MMU The small page MMU support reduces the granularity for memory settings through the MMU from 1MiB sections to 4KiB small pages. Enable it by default on the realview_pbx_a9_qemu BSP. A BSP needs some minor changes to support it. -- embedded brains GmbH Sebastian HUBER Dornierstr. 4 82178 Puchheim Germany email: sebastian.hu...@embedded-brains.de Phone: +49-89-18 94 741 - 16 Fax: +49-89-18 94 741 - 08 PGP: Public key available on request. embedded brains GmbH Registergericht: Amtsgericht München Registernummer: HRB 157899 Vertretungsberechtigte Geschäftsführer: Peter Rasmussen, Thomas Dörfler Unsere Datenschutzerklärung finden Sie hier: https://embedded-brains.de/datenschutzerklaerung/ _______________________________________________ users mailing list users@rtems.org http://lists.rtems.org/mailman/listinfo/users
