From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0) Description of problem: 'serial.c' calls the serial device driver's 'set_config' with key 'CYG_IO_SET_CONFIG_SERIAL_HW_RX_FLOW_THROTTLE', 'buf' points to a 'cyg_uint32' buffer. At least two serial device drivers, 'ser_16x5x.c' and 'sh_scif_serial.c', assume 'buf' points to a 'cyg_uint8'. A big-endian target will fail. I suspect most serial device drivers will have this problem because they all seem be derived from the same source. This problem is not limited to the 2.0 beta. It also appears in the CVS sources. I suggest better comments in 'serial.h' could have prevented this. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Examine the code. 2. 3. Additional info:
