2026-08-18dcd(ip3511): fix DEVCMDSTAT write-1-to-clear handling and EP0 setup raceshathach
DEVCMDSTAT mixes read/write fields with write-1-to-clear latches, so a blind read-modify-write writes a pending latch back as a one and silently clears it - a setup consumed that way strands EP0. Mask the latches on every update. The setup path follows the manual's order: acknowledge the latch, then read the payload. The EP0 IN interrupt is cleared along with EP0 OUT, as the control endpoint flowchart requires - a control IN completion latched before the setup must not reach usbd after it, where it would be applied to the request the setup just started and arm its status stage early. The payload is copied a byte at a time out of a buffer now declared volatile: the controller DMAs a new setup packet into it as soon as the latch is cleared, and C orders volatile accesses only against each other, so gcc sinks a plain memcpy below the guard read that follows at -O2 and -O3 - leaving only -Os, the level CI builds, correct.
2026-07-12dcd(ip3511): clear Active directly on stall/iso-activate, keep EPSKIP for reopenhathach
EPSKIP raises a transfer completion, so using it on the stall path let the class re-arm the endpoint and Active+Stall never actually stalled (usbtest case 13); write bare Active=0 instead, and retire skipped transfers on endpoint reopen where the completion is wanted. Verified: usbtest 30/30 on lpcxpresso11u37. Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg
2026-07-09dcd(ip3511): iso alloc/activate; retire armed buffers via EPSKIPhathach
Clear Active before Stall so a queued endpoint actually halts (UM11126 41.8.1); use the sanctioned EPSKIP+wait sequence for stall/reopen/activate. Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg
