/**
* @brief Hardware CRC-32 update function
*
* Configuration that works (Test 2):
* - Polynomial: 0x04C11DB7 (direct form)
* - Write data swap: BYTE_BIT (byte + bit reflection on input)
* - Read data swap: BYTE_BIT (byte + bit reflection on output)
* - Read data FXOR: FXOR (final XOR with 0xFFFFFFFF)
*
* This matches the software implementation that uses reflected polynomial 0xEDB88320.
*
* @param crc Initial CRC value (0xFFFFFFFF for new calculation)
* @param data Pointer to data buffer
* @param len Length of data in bytes
* @param update_func Callback for timeout (can be NULL)
* @param update_func_env Environment for callback
* @param timeout Timeout in milliseconds
* @return uint32_t Updated CRC value
