Branch: refs/heads/main Home: https://github.com/OpenAMP/open-amp Commit: 79b795e954e15d0d7c37d49fd32ac9cc0315bc3c https://github.com/OpenAMP/open-amp/commit/79b795e954e15d0d7c37d49fd32ac9cc… Author: Umair Khan <umair_khan(a)mentor.com> Date: 2024-02-29 (Thu, 29 Feb 2024) Changed paths: M lib/remoteproc/elf_loader.c Log Message: ----------- remoteproc: Fix management of non loadable program segments The elf loader assumes that the last ELF program segment will always be a LOAD type segment. I deduce this from the fact that the elf_load() function, when loading the remote ELF sections during the RPROC_LOADER_READY_TO_LOAD stage, compares the last load segment num to the total ELF sections to determine if the loading is complete and it can move to the next stage RPROC_LOADER_POST_DATA_LOAD. If the last program segment in the ELF is not of type LOAD, the last loaded LOAD segment never equals total ELF sections. This creates an error condition and the firmware loading fails. This patch fixes this issue by comparing the last loaded LOAD segment number with the max LOAD segment number in the ELF.

by Muhammad Umair Khan

Branch: refs/heads/main Home: https://github.com/OpenAMP/open-amp Commit: f94dde55e0f06809c331513641e0482bafe3d390 https://github.com/OpenAMP/open-amp/commit/f94dde55e0f06809c331513641e0482b… Author: Umair Khan <umair_khan(a)mentor.com> Date: 2024-02-22 (Thu, 22 Feb 2024) Changed paths: M apps/examples/load_fw/load_fw.c Log Message: ----------- load_fw: The firmware loading loop terminates prematurely The remoteproc_load_noblock() is a non-blocking API designed to load the remote firmware in streaming mode. The application has to continue supplying the firmware data blocks until the complete firmware is loaded. The load_fw example does this and checks the `nlen` variable (returned by the remoteproc_load_noblock() API) for zero to determine if the firmware loading is complete. However, `nlen` (contains the filesize of the next program header) alone can't be taken as the sufficient condition to mark the completion of firmware loading as 0 is a valid value for filesize for sections that don't require loading to the target memory such as the .bss section. This patch proposes checking filesize as well as memsize as a better metric to mark completion of the firmware loading loop.
