[PATCH] bsps/aarch64/zynqmp/nand: Erase using offset
Prefer use of XNandPsu_Erase instead of XNandPsu_EraseBlock since the
XNandPsu driver does not expose the primitives necessary to ensure
device readiness after the operation is complete.

For example I have not looked into TLS and there is the failure of the tests in the testsuite (dl06). RAP is an intermediate format where a lot of the required linking can be done on the host and the file set you need for the target can be collected. This lets you have a golden base image and a single loadable application. > Can I load also archives? It seems this can be done through configuration > files. > Are there API calls to do this? Currently there is no API call available. One could be added if you feel it is required. I decided you need a valid file system for loading to work so a configuration file was the simplest method. Loading from archives is done via the /etc/libdl.conf file: https://git.rtems.org/rtems/tree/testsuites/libtests/dl10/etc/libdl.conf The file can be updated at runtime and it is checked on each load for changes. Note, I did some initial analysis for this at the time the change was made and if you use runlib on the archives before loading the symbol table for libraries like libc is manageable.

Re: [PATCH v1] bsps/aarch64: translation table walk disable for translations using ttbr1
This change looks good. TTBR1 isn't used at all under the current RTEMS configuration and isn't expected to be used in the future.

libdl documentation?
Hello, I tried to get a bit more familiar with the libdl. Is there some documentation available? I tried the user manual, but I see only a work in progress page: https://docs.rtems.org/branches/master/user/tools/linker.html For example, I can use dlopen() to load an object file (ELF). For what do I need RAP files? Can I load also archives? It seems this can be done through configuration files. Are there API calls to do this? -- embedded brains GmbH Herr 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 Registergericht: Amtsgericht München Registernummer: HRB 157899 Vertretungsberechtigte Geschäftsführer: Peter Rasmussen, Thomas Dörfler Unsere Datenschutzerklärung finden Sie hier: https://embedded-brains.de/datenschutzerklaerung/ ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
