Deployment Final Checks

• The code should be audited for the following aspects, as a final check before the final flash.

Automated Check Ideas (GitHub Actions)

1. ✅ Telecommand Execution (TCMDEXEC_) function names match their registrations in the table.
   • Implemented in check_tcmd_function_names_match_registration_names().
2. No malloc usage.
3. ✅ Are all TEST_EXEC_ functions registered in the test table?
   • Implemented in validate_test_exec_registration().
4. ✅ Are all TCMDEXEC_ functions registered in the telecommand table?
   • Implemented in validate_tcmdexec_registration().

✅ = Automated test now exists.

Manual Execution Checks

The following checks involve executing code and/or telecommands.

• Units tests pass.
• Python-based system tests/checks pass.

Logging Checks

1. Are all logs to LOG_message()? Limited use of UART logging.
2. Are LOG_message() calls using the correct exclusions and levels?
3. Are the log levels appropriate? Logs right before non-zero returns should generally be a warning/error level.
4. Are the log format strings consistent with the actual arguments? TODO: Find a build option to enable this.

Other Checks

1. Check the changelog of libraries (LittleFS, CSP maybe) for bug fixes.
2. Are there any large VLA allocations? Can/should any be replaced with static allocations?
   • Maybe enable -Wvla or -Wstack-usage? Not sure what they are yet.
3. Maybe enable compiler optimizations?
4. Ensure that the Golden Copy is mapped in STM32L4R5ZITx_FLASH.ld file as such:

   GOLDEN_COPY (xrw) : ORIGIN = 0x8100000, LENGTH = 1024K

   This is the linker script. The length can change.
5. Ensure that we have flashed the golden copy of the OS to the GOLDEN_COPY address defined in the linker script STM32L4R5ZITx_FLASH.ld
6. Ensure all tasks are registered in the FREERTOS_task_info_struct_t FREERTOS_task_handles_array [] array. Consider a unit test for this check, maybe.
7. Ensure the BOOT0 pin configuration is applied using STM32CubeProgrammer.
   • nSWBOOT0 = Unchecked (use software config)
   • nBOOT0 = Checked (boot from system memory)
8. Check that the sum of the stack sizes of all the tasks (in main.c) sums to less than the configTOTAL_HEAP_SIZE in FreeRTOSConfig.h (plus a margin).

Management Checks

1. Are all the requirements met?
2. Are all GitHub Issues implemented and/or closed as not implemented.
3. Are all PRs merged?
4. Are all branches merged?
5. Ctrl+Shift+F for TODO and FIXME in the codebase.
