From 34aded88edd5b1403bb35b531985953502a0faab Mon Sep 17 00:00:00 2001 From: Fan DANG Date: Mon, 13 Apr 2026 08:56:36 +0800 Subject: fix(device): big-endian host support for SETUP packet handling 1. Add TU_LITTLE_ENDIAN_BITFIELD / TU_BIG_ENDIAN_BITFIELD macros in tusb_compiler.h (GCC and IAR), following Linux kernel style. 2. Update bmAttributes (tusb_desc_endpoint_t) and bmRequestType_bit (tusb_control_request_t) in tusb_types.h to use these macros with explicit #error fallback if undefined. 3. Add tu_le16toh() conversion in dcd_event_setup_received() for wValue/wIndex/wLength. Tested on CIU98320B (big-endian ARM Cortex-M, full-speed HID keyboard). --- src/device/dcd.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'src/device') diff --git a/src/device/dcd.h b/src/device/dcd.h index 850c37bc2..f861eb258 100644 --- a/src/device/dcd.h +++ b/src/device/dcd.h @@ -219,6 +219,11 @@ TU_ATTR_ALWAYS_INLINE static inline void dcd_event_setup_received(uint8_t rhport event.rhport = rhport; event.event_id = DCD_EVENT_SETUP_RECEIVED; (void) memcpy(&event.setup_received, setup, sizeof(tusb_control_request_t)); + // USB wire format is little-endian.
