Hi,
I am testing our board using DM6437, and got a strange problem on UART example that comes with BIOS_5_33_03: dvsdk_1_00_00_19\PSP_0_05_03\pspdrivers\drivers\uart\sample.
When build in Debug setting, everything works fine. Following is the response through UART0 port:
UART Demo Starts
Enter 32 characters for read write test :
I am good.Thanks. how about you?
UART Demo End
However, when build in Release setting, only "UART Demo Starts" was received at PC side, not even the following "\r\n".
Note: If I changed the PSP_OPMODE_INTERRUPT to PSP_OPMODE_POLLED, both Debug and Release builds works well.
Can anyone give me hint what may be wrong in PSP_OPMODE_INTERRUPT mode?
Thanks.
Alan
