From ca402a0e781eb4d5580030f713377552b72eddda Mon Sep 17 00:00:00 2001 From: hathach Date: Tue, 14 Jul 2026 15:23:07 +0700 Subject: dcd(ci_hs): stale overlay fix; run usbtest on lpcxpresso43s67 - dcd_edpt_stall flushes the primed buffer (ENDPTFLUSH), but the aborted transfer's dQH overlay can be left ACTIVE with mid-transfer state; the next prime after clear-halt then resumes the stale overlay instead of loading the fresh qtd, so post-halt IN reads return mid-buffer data (usbtest case 13 'buf[32] = 56 (not 0)', with case 18 failing downstream of the same corruption in the full battery). qhd_start_xfer now clears overlay.active alongside overlay.halted before linking the new qtd. - test/hil(hfp): drop lpcxpresso43s67's device/usbtest skip - the historical first-case wedge no longer reproduces on this branch, and with the overlay fix the board runs 30/30 on its Fresco xHCI host (previously 28/30 with deterministic case 13/18 failures). mimxrt1064_evk (imxrt dcache path) 30/30 regression-clean. - docs(hil skill): document the external hifiphile rig - pool test/hil/hfp.json, SSH-reachable from htpc/ci with no outbound SSH, exercised by the CI hil-tinyusb (hfp.json) job; never run HIL against it during development unless the user explicitly asks.
