The provided ecos_stm3220g_eval_plf_adc1 executes on the
STM3220G-EVAL hardware platform using DMA driven ADC, where the DMA is
triggered by a configured timer (TRGO).
Due to the interconnected nature of the H/W controller configuration more than one model needs to be updated to correctly simulate the required functionality.
This fork will eventually provide updated models as required to successully execute the test. The initial commit is against an unmodified Renode environment to exhibit the missing features.
NOTE: The, pending, locally "fixed" models have already
successfully run 1000s of eCos testfarm cases under Renode 1.14.0 and
1.15.0 as well as on the real H/W platform. The specific test
application ecos_stm3220g_eval_plf_adc1 is provided as an ELF image
due to the large number of source files involved and the normal eCos
config+build world using "custom" tools that would just add workload
onto providing a failing example for Renode.
Since the automated test world we use internally does not make use of the "robot" mechanism, the "test.robot" will be updated as needed as more of the application execution succeeds using this issue framework.
The following table provides a basic overview of the changes required to support timer driver DMA based ADC sampling as exercised by the test ELF. The "Pending" state just indicates that the relevant changesets have not yet been applied to this repo.
