From d9dc891ee2aaedb733da4c0f2fee5a68be001ee7 Mon Sep 17 00:00:00 2001 From: hathach Date: Thu, 18 Jun 2026 18:08:25 +0700 Subject: test/hil: fix esp32 audio_test_freertos (FreeRTOS tick), skip metro_m4 Enabling the audio test fleet-wide surfaced failures on esp32-p4/s3 and metro_m4_express: the UAC mic enumerates but arecord fails the iso IN read with EIO, while 18 other boards pass strict=1.000. esp32: root cause is the FreeRTOS tick rate. ESP-IDF defaults CONFIG_FREERTOS_HZ to 100, so the audio task wakes only every 10 ms and can't service the 1 ms UAC iso frames -> underrun -> arecord EIO. (The same dwc2 driver passes on STM32, whose FreeRTOSConfig is 1000 Hz.) Set CONFIG_FREERTOS_HZ=1000 in the example sdkconfig.defaults; the example defaults are honored in the generated sdkconfig alongside the BSP's, so this takes effect. metro_m4_express (samd51): not tick-rate -- its FreeRTOSConfig is already 1000 Hz like the passing boards -- so it's a separate iso-IN issue, skipped for now.
