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/common/tusb_compiler.h | 4 ++++ src/common/tusb_types.h | 17 +++++++++++++++++ src/device/dcd.h | 5 +++++ 3 files changed, 26 insertions(+) diff --git a/src/common/tusb_compiler.h b/src/common/tusb_compiler.h index f20834cea..e66bcc5ea 100644 --- a/src/common/tusb_compiler.h +++ b/src/common/tusb_compiler.h @@ -167,8 +167,10 @@ // For TI ARM compiler, __BYTE_ORDER__ is not defined for MSP430 but still LE #if __BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__ || defined(__MSP430__) #define TU_BYTE_ORDER TU_LITTLE_ENDIAN + #define TU_LITTLE_ENDIAN_BITFIELD #else #define TU_BYTE_ORDER TU_BIG_ENDIAN + #define TU_BIG_ENDIAN_BITFIELD #endif // Unfortunately XC16 doesn't provide builtins for 32bit endian conversion @@ -212,8 +214,10 @@ // Endian conversion use well-known host to network (big endian) naming #if __BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__ #define TU_BYTE_ORDER TU_LITTLE_ENDIAN + #define TU_LITTLE_ENDIAN_BITFIELD #else #define TU_BYTE_ORDER TU_BIG_ENDIAN + #define TU_BIG_ENDIAN_BITFIELD #endif #define TU_BSWAP16(u16) (__iar_builtin_REV16(u16)) diff --git a/src/common/tusb_types.h b/src/common/tusb_types.h index a18f9feb7..b02e90eae 100644 --- a/src/common/tusb_types.h +++ b/src/common/tusb_types.h @@ -409,10 +409,19 @@ typedef struct TU_ATTR_PACKED { uint8_t bEndpointAddress ; // The address of the endpoint struct TU_ATTR_PACKED { +#if defined(TU_LITTLE_ENDIAN_BITFIELD) uint8_t xfer : 2; // Control, ISO, Bulk, Interrupt uint8_t sync : 2; // None, Asynchronous, Adaptive, Synchronous uint8_t usage : 2; // Data, Feedback, Implicit feedback uint8_t : 2; +#elif defined(TU_BIG_ENDIAN_BITFIELD) + uint8_t : 2; + uint8_t usage : 2; + uint8_t sync : 2; + uint8_t xfer : 2; +#else + #error "Please define TU_LITTLE_ENDIAN_BITFIELD or TU_BIG_ENDIAN_BITFIELD" +#endif } bmAttributes; uint16_t wMaxPacketSize ; // Bit 10..0 : max packet size, bit 12..11 additional transaction per highspeed micro-frame @@ -522,9 +531,17 @@ typedef struct TU_ATTR_PACKED { typedef struct TU_ATTR_PACKED { union { struct TU_ATTR_PACKED { +#if defined(TU_LITTLE_ENDIAN_BITFIELD) uint8_t recipient : 5; ///< Recipient type tusb_request_recipient_t. uint8_t type : 2; ///< Request type tusb_request_type_t. uint8_t direction : 1; ///< Direction type. tusb_dir_t +#elif defined(TU_BIG_ENDIAN_BITFIELD) + uint8_t direction : 1; ///< Direction type. tusb_dir_t + uint8_t type : 2; ///< Request type tusb_request_type_t. + uint8_t recipient : 5; ///< Recipient type tusb_request_recipient_t. +#else + #error "Please define TU_LITTLE_ENDIAN_BITFIELD or TU_BIG_ENDIAN_BITFIELD" +#endif } bmRequestType_bit; uint8_t bmRequestType; 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.
