| Interactor session | Review, as a fresh reader: why does no firmware flashed onto the BeagleConnect Zepto (TI MSPM0L1117) appear to run? Find a basic requirement that the build or the flashing misses. Report findings; don't redesign anything. Read badge-demo/firmware/zepto: - platformio.ini, boards/zeptomspm0l1117.json, the builder under platforms/zepto-mspm0/ - linker/zeptomspm0l1117.ld, src/startup_mspm0l1117.c, src/zepto_board.c, include/zepto_board.h - examples/baremetal/blink/src/main.c - scripts/build_zepto.cr Also read badge-demo/docs/ZeptoFlashing.md, badge-demo/docs/ZeptoControlWiring.md, badge-demo/docs/MSPM0L111xDataSheet.md, and the flasher: badge-demo/bridge/src/hardware.cr and bsl.cr, plus scripts/flash_zepto_bsl_direct_i2c.py, which the bridge follows. Check: - clocks and the SYSCTL state after reset - peripheral power enable (PWREN) for GPIOA - the IOMUX PINCM addresses and values for PA13 - the vector table, the initial stack pointer and Reset_Handler - the BSL entry and exit sequence: BSL on badge gpiochip1 line 27, RESET on line 28, both still left driven as outputs after the flasher ends - whether START_APPLICATION or a reset with BSL low should start the application - NONMAIN or BCR settings: whether a mass erase or the factory configuration blocks the application from booting, or needs a CRC or "app valid" check - anything else basic What is known (Nov 4-5): - Every flash reports connect, device_info (build 0x0100, plugin 0x1001, max_buffer 7668), unlock, mass_erase, program_data and start_application ok. - The maintainer believes the June 23 PlatformIO blink once blinked PA13 (the board's "USR: PA13" LED). That image (364 bytes, sha256 …, built from check-in “zepto: move blink led to pa13”) was flashed at 12:40 AM Nov 5 Eastern with every step ok. PA13 stays dark. - So do current builds, including check-in “zepto_board_init: power up GPIOA (reset, PWREN) before driving pins; without it every pin write was ignored, so no app could light PA13, the backlight or the panel lines”, which adds a GPIOA reset and PWREN to zepto_board_init (my unconfirmed guess). So does an IPS-display build whose backlight stays off. - After `zepto-bridge reset` (RESET pulsed low for 0.1 s with BSL low, then RESET held high for 0.12 s, then the lines are released, still outputs), the BSL connection packet sent to 0x48 three times got NACK (run “Interactor session”, 1:05 AM). So the Zepto is not sitting in the bootloader. Whether it runs the application, or is held in reset, is unknown. - Pressing the Zepto's own RESET button did not start a blink. Rules: no Python, pip or PlatformIO. Building with `crystal run firmware/zepto/scripts/build_zepto.cr` is fine if arm-none-eabi-gcc is on PATH; otherwise review by reading. Times in US Eastern, never UTC. Remove lib/, bin/, .shards/ and any caches or build/ output before your last message. Your last message: the findings ranked by likelihood. For each, give the file and line, the TI document or section it rests on, and the smallest test that would confirm it on hardware. | x86-1-interactor | codex-task | ended: exited, exit 0 | 6 days ago |
