sysview: fix cycle-2 review findings

2026-09-03T22:11:02Z

- sysview_ci.py: wait() after kill() on the OpenOCD/nc grace-period timeout, so a still-exiting process can't hold the probe when the recovery flash starts - SKILL.md: point the OpenOCD and post-mortem recipes at examples/device/cdc_msc_freertos, where build-sv actually lands - stm32f401blackpill: override SYSVIEW_BUFFER_SIZE_DEFAULT to 4096; the 64 KiB part overflows RAM by 12952 bytes at the family's 65536 default under SYSVIEW=4 - get_deps.py: align the SystemView entry's continuation lines

sysview: per-family RTT buffer defaults, 65536 on RAM-rich parts

2026-09-03T21:21:57Z

The dual-role dogfood measured the 4096 fallback losing 96.7% of ISR exit contexts on mimxrt1064_evk and 99.1% on metro_m4_express; a local-board run measured stm32u575nucleo losing ~19% of the whole stream under a 12 s cdc_msc workload. The default was too small for any real capture on fast parts and every user had to rediscover that per board. Families now declare SYSVIEW_BUFFER_SIZE_DEFAULT in family.cmake (the SYSVIEW_RAM_BASE_DEFAULT pattern): imxrt, nrf, rp2040, samd5x_e5x, stm32f4, stm32f7, stm32h7 and stm32u5 set 65536, the measured-safe value. -DSYSVIEW_BUFFER_SIZE still beats everything; small-RAM parts keep the 4096 fallback and their per-board overrides (stm32f072disco's 2048 verified still honoured). lpc55 measured 34 lost events on the same route, an order of magnitude lighter, so it keeps the fallback rather than inheriting a default on thin evidence.

sysview: FreeRTOS trace hooks, stack high-water and heap tracking

2026-09-03T21:21:57Z

hw/bsp/sysview_freertos_hooks.h maps the FreeRTOS trace macros onto SystemView task records (task names, switches, ready/blocked) and adds heap tracking; the FreeRTOSConfig.h of the families used on the rig include it when SYSVIEW is on. The FreeRTOS examples grow their USB task stacks when CFG_TU*_SYSVIEW is enabled, the same way they already do for CFG_TUSB_DEBUG -- the instrumentation's stack cost is real (measured overflows on lpc55 before the bump).

remove IAR toolchain support from make build system

2026-04-06T04:17:34Z

IAR is only supported with CMake. Remove all IAR-specific references from the Make build system including toolchain files, SRC_S_IAR, LD_FILE_IAR variables, and IAR toolchain detection. Also fix GET_SECTOR_COUNT truncation in msc_file_explorer and broken formatting in stm32f7 board_uart_write. Co-Authored-By: Claude Opus 4.6 (1M context)
