In upgrading from 3.7 to 3.8 I found that printf was broken. I was using a series of "%c%c" format to generate a Modbus packet to a sensor. Printf in 3.7 did the right thing with a '\0' character (sent a null character) but in 3.8, it ignores it and does not output anything. I was able to work around it by using a series of "fputc()" calls instead. I did submit a bug report to Freescale but I have not heard back.
It may be that in user_config.h that the BSP_DEFAULT_IO_OPEN_MODE is set to this
#define BSP_DEFAULT_IO_OPEN_MODE (pointer) (IO_SERIAL_XON_XOFF | IO_SERIAL_TRANSLATION)
Try this
#define BSP_DEFAULT_IO_OPEN_MODE (pointer) (IO_SERIAL_XON_XOFF | IO_SERIAL_RAW_IO)
Hello PhilH,
I took a quick look what you have described. It's been reported and I will let you know here when this is fixed.
The defines (BSP_DEFAULT_IO_OPEN_MODE) do not have any affect to this problem.
Thank you for your finding!
Regards,
