HI,
UART0 receive problem:I program a 9G45 software communication with PC using UART0.find software only receive data when PC send large than 2K byte data. for exemple, PC send 500 byte data to 9G45,the software cann't receive the data.when PC send 2K byte data ,software receive the entire data PC send.In serial driver,the receive buffer is 10K,I change it to 1K.but cann't affect this problem.
How to resolve this problem? Thanks for you help!

Find the 9G45 cann't generate Receive Timeout,how to resolve?already set the Control Register(US_CR) with RTTTO bit at 1,and TO field of US_RTOR as 0xC0.but 9G45 cann't generate TIMEOUT intterupt, when receive interval time large than the TIMEOUT period.
