Solved Problem
Although MatekH743-Slim doesn't have mountable onboard FLASH/EEPROM, PX4 startup script tries to mount "/fs/mtd_params", which fails and so the parameter system doesn't work at all.
Solution
Add
+CONFIG_BOARD_PARAM_FILE="/fs/microsd/params"to boardconfig file: https://github.com/PX4/PX4-Autopilot/blob/main/boards/matek/h743-slim/default.px4boardChangelog Entry
For release notes:
Test coverage
After change, flashing the new firmware allows saving modified parameters correctly.
